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.
