Modern gold extraction methods

Have used many methods to extract gold throughout history, at the moment there are several ways followed for gold extraction, Festal as follows: extracting the gold found in the silt and riverbeds gold resides crude form in some of the stones in streams rivers and estuaries, used this method and is still used to the present, and that by doing a manual search in stone deposits in the bottoms of waterways, where it is likely that the gold is present in large quantities, are getting these sediments, and then extract the gold of them by washing and screening, out of date, this process is done by hand sieves, workers where to search for gold in view, but currently is used giant machines to withdraw large amounts of sediment in the river bottoms, and a process of gold including extraction, taking advantage of the fact that gold is more dense metals, so you can find stones containing gold in the bottom of the screening devices. Gold extraction by drilling in the mines there are large amounts of gold found in certain rock formations, the so-called gold mines, the stone crushing in these mines by cracking machines giant, has been the use of explosives in the process, it is then crushed into pieces small, and carry out the gold ones extracted by carrying out a number of purification operations, which include smelting stones, and get gold of them in liquid form, is subject to work in these quarries are many considerations, the most important is the price of gold in the market, and the percentage of gold in the stones, as when the ratio is less than a certain extent become the gold extraction processes is useless.Extract gold from the ground in some places exist underground gold soles in large quantities to allow commercial exploitation of it, are dug pits horizontal to the ground, and the introduction of tubes or mechanical devices are bringing in rocks containing the gold out of the ground, and is performed my usual treatment processes. Find the golden sunken treasures and buried because of the value of the high gold, make a lot of attempts to find a golden sunken treasures, where a group of hobbyists or professionals to track information about the whereabouts of the sunken ship, which was carrying a golden treasures, and carry out diving around, and get what out of the golden treasures, and also there is some information that appears from time to time about the existence of the golden treasures buried in the ground, and these treasures have been associated in popular culture pirate maps with stories that guide the place of buried treasures, trying some people keep track of information about these treasures,and the pursuit behind them, but in the majority of cases do not have access to the results he, also there are efforts occur in countries that contain gold effects, where a lot of people trying to access these effects for quick riches.

Damages gold mining on the environment

Cause operations of gold extraction unfair a lot of damage on the 
surrounding environment, as the extractions lead to changing the features of geologic place that has been mining it, also affect the materials used in gold purify the processes of nature, not to mention the mines that occur from time to time accidents, and cause injury or death of a lot of workers each year. We talked about the gold, we've included some of the properties and uses, and we talked about the historical development of the operations of gold extraction, and then we talked about the ways of the modern gold extraction, including the extraction of gold from riverbeds, and extract gold from gold mines, extracting gold from the ground, as well as talked about searches for gold effects sunken and buried, and finally we talked about the damage to the environment gold unfair extraction operations.

How is the extraction of gold from the dirt?

Extraction method differ on the following basis: -

1-Gold ratio in the sample

2-size gold particles ..mriah..mkroskubih..k ..

3-type metal interlaced with gold

As for Trqastkhalas gold are:

One-way Alsianid..okvotrq

2-way water royalist ... you need to Draahbouktorh gases and also gold deposition process of the dissolved minerals him be Makdhgheir chemists Experience

3-way Alrsasouy Totybnsph 100% of the gold found fit microscopic samples ..lkn flawed

Cost a-

b- gravity gold recovery process, which is called a Cupellation Zbboboukrh lead to a very large

4-way mercury ..kavaih this method does not exceed 40% in addition to that they are not suitable for microscopic samples ..ohnaonoh that gold recovery method is a way of distellation.

There are ways to rely on Trdantrzy .. but these roads not fit but with samples that contain visible pieces Manalzhboo at least not overlapping with the silica particles.

Before talking about the extraction methods I would like to recall information ..alzhb does not have a composite body never, but no independent in the form of either a very small pieces or large pieces visible and sometimes blocks up to several ounces but most gold presence in the form of microscopic overlapping with existing him silica particles .

Here is the first method

One-way cyanide ..: - This method is also mentioned is the best way in terms of

1-the total cost.

2. The amount of environmentally harmful pollutants.

3. extraction efficiency ..hat its efficiency up to 96%.

4. The ability to make recycling of materials used again.

Steps way: -

1. Milling: It is very necessary in the extraction of gold in all ways, but in the way the cyanide is particularly important because it has to be that it does not exceed the size of granules Ackoran 100 microns and thus this method efficiency depends on the efficiency of the grinding .... and this image of a mill used in milling.

2. Focus: It is a method that relies on higher gold mineral density (density quality 19) and which are flipping crushed rocks in a large metal cylinder even down to the bottom of the gold particles and thus increase the concentration of gold at the bottom and thus be the result of a good recovery.

How to extract gold

It symbolizes gold among the items by the periodic table of the elements of the symbol (Au), and is one of the metals, expensive, exists in nature where it is mined and extracted from the ground, and called and is in its natural state any and is in the ground Baltbr, used gold jewelry that adorned by women and men in various parts of the world industry, due to the aesthetics and Aonth, which facilitates the formation process and the design of various shapes using it, as it was used in ancient times as a currency in cash for the states in the centuries-old along with silver, where the coins were Tsk them, but today and after the establishment of the currency paper gold place, to facilitate trade transactions and facilitate the movement and carry out, the Alzha used as a reserve established by the state to give a monetary value of paper currency. All this and more important for this precious element uses. A country that gold resides in its territory, becoming very rich in this case that the rest of the countries left in the same, as has happened with African countries, which assailed the colonial powers and plundered their wealth. Given the scarcity of this important nature element, the scientists and specifically Muslim scholars in the old worked to make the rest of the different metals to gold, but failed to do so, to be the gold needs special conditions difficult availability, including high temperatures, but scientists in the modern era they were able to turn the other elements of gold by neutron collisions, or through the use of nuclear reactors, but these methods are expensive methods of price and costs. Known gold mining gold mining process, and are extracting gold from the ground through the roads were formed primitive and may be new ways of using machines and new equipment, either phases of mining is up by digging holes in the ground to give the whereabouts of crude in the ground, after studying geological wherever they are located, are then extracted from the ground, Afikz strong water until the wash and remove suspended him from clay and impurities. It also is gold recovery by accident when the extraction of silver and copper, as it is the use of chemical methods Kaltdhuab in sulfuric acid. The places that are called them to extract gold mines, and is deployed in the areas which is famous for the presence of gold and employs a large number of people.

Production line for gold CIP

About Line

The use of activated carbon to absorb gold from the clay cyanide. The process includes seven parts: clay cyanide preparation, nominated cyanide, carbon absorption, reverse absorption, electrolysis for gold clay, re-cycling of carbon, and treatment of mud

Applied areas

Is applicable to the two types of minerals, Aloolanha apply to two types of minerals, the first is a metal went through the exact flotation process or final metals by sorting Althagla, the second is Aloksidih metals are sandy

Detailing Line

Removing Impurity

Before absorption must remove impurity, for example, sawdust in the mud cyanide, to avoid gold-enter the sawdust

Leaching and absorption

Adding activated carbon to the leaching tanks, making the carbon absorbed by the gold in the mud, after absorption, carbon sequestration and carbon mud Braf

Unlike absorption and electrolysis

In the high-pressure environment, heat, carbon pregnant gold turns to mud gold and carbon cheap

Smelting

After a simple process to remove impurities, it can melt mud into gold blocks

Electrolysis system of high-speed high-efficiency and energy-saving

This system has self-control high pressure and temperature analysis and sucking, at the same time, characterized by high efficiency and high-speed energy saving

High Efficiency: When the degree of gold in the carbon of up to 3000 grams per tonne, reversing absorption rate can be up to 96%

Automatic control: put the system to the point of controlling flood and temperature and the system controlling automatic especially

Super speed: due to the high temperature and Aldaht, time analysis, it fell to 12 hours, which is 70% of the normal time

Energy saving: due to the same temperature for the analysis of electric and not need to change the temperature also subject to act quickly have gross volume of electrical energy Alsthlak is a half or a quarter of the regular setups 02/01 to 04/01

Free from cyanide: not Alanaaj to enter low-free Atawait Vtkfattha

High degree of clay gold: there needs to electric counter-analysis, making it easier extraction

Automatic control: put the system to the point of controlling flood and temperature and the system controlling automatic especially

How do you know places (gold) and extraction

Gold precious metal resides across the land in two ways only to change

1. raw gold

2. Gold is buried

-------------------------------------------------- -------------------------------------------------

1-Gold and Crude

We know that the land where the treasures of gold ore every square meter of the earth's surface

But how to know and how Amaknyh benefit from it

There are two things to detect the presence of gold

1_ detection devices used to detect metal gold

((((And should be cautious in buying devices because there is fraud and falsifying purchase through experience

Personal buyer))))

2_ or through natural appearances by the naked eye

First gold in rocks and mountains, you know, through the veins in the rocks

Mountains or Kckheot decree and slightly bent (for yellow or red)

But what is important in this case

Are there gains through extraction and the quantity ubiquitous

QUANTITY know through our exploration experts estimated the quantity of through hardware

But if a person wanted to Astkhrjh himself he must carry the load like Maicoloa

You and Houdk

Be drilling and fracturing of rocks and then is crushed. They have to machines for grinding even if small

To grind rocks and then put lotion on the ground to filter the rocks

And extraction of gold granules

In this way but you must have learned that it is not as easy as hard needs a total of sharing

Including work

You must know that all governments known deposits of gold in their own home, but does not try to think or

Extracted in a simple reason:

Because the cost will be greater than the extraction: therefore it never Aevkron

2. The second type of gold buried

No to him and tens of thousands of years Maiat and was buried Living situation to what 0

By rulers, traders and thieves to take advantage of it and Astkhrjoh

This is his story tale and must use the jinn and prepare them to be extracted safely

And easily and conveniently

Calculate the cost of gold extraction

Points are very important too overlooked when everyone solves gold without calculating the actual cost prices for the extraction of gold, although it tipping point in determining the calories !!
Now what Aalaspab which control the cost of gold extraction There are administrative expenses and salaries for workers' wages and exploration equipment. Finally, and most importantly energy prices used for exploration amid rocks and purification of gold from Alhaaib suspended amid tons of rock
And therefore the oil and gas price affects directly the price of extraction of gold per ounce and the more energy and oil prices rose whenever it grew cost of extracting Dahab rose calories and vice versa whenever oil prices collapsed whenever pressure negatively on the cost of gold extraction and led to lower calories and example of this when he was oil in the past two years touches the $ 100 per barrel prices, the price of gold extraction above the $ 1,200 per ounce !!! When collapsed oil prices and arrived at what the case has now broken the $ 80 per barrel, the cost of gold extraction does not exceed 800 to $ 950 depending on location, location, the mine extracted gold and here starts a serious dialogue ... because if gold fell below 1,100 dollars will be closed immediately mines where the price of extracting excess ounce from 1,100 dollars and lasts only mines that produce gold at a price of $ 900 until you stop all the mines when the collapse of gold and break the barrier of US $ 900_800 Hence, supply is less definitive and saturated sales and the start of the emergence of large orders for speculators and then begins to climb trip another wave of large boarding flights
The second factor inverse association of gold at a price of USD INDEX link and it grew as the dollar collapsed gold which is what happened in the past ... and also a rise in stock prices and high interest rates on bonds makes the appetite of investors to rush to a few gold and therefore less demand for gold ...... .... and of course there are the oil price factor has been described previously
The third factor .... economic decisions producing countries Dahab has happened in nearly three years almost that Russia announced a dramatic financial crisis and the decision was Russian experts to sell a very large part of the tons of gold stocks have to achieve financial liquidity was the same decision was made Mahmoah European countries when the crisis Poddar bankrupt Greece, Cyprus and Bulgaria, which ultimately led to a very large Bebaah pressure on the gold out of the grinding financial crisis hit in Europe
Fourth Technical Analysis for gold chart is showing that gold live inside the triangle very tight between the 1280 dollars to to $ 1150 and a candidate to break the triangle down to $ 1930 area to touch the lower limit of the bearish channel and advised to purchase from the 1980 area to $ 1930 for Astosmaralamn in batches, a region very safe for purchase and can start buying adventure than $ 1010 an ounce area
