When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
Crush and mill the gold ore to dust like particles. Ore is put into the crusher, which breaks it up. Water is added during the process which, when mixed to the ore particles, creates a pulp. Zinc dust is added to separate the gold from the solution. The gold is then put through a filter press, which separates it from the solution. Step.

Refining gold from ore or concentrates is done during the smelting process. During this process, flux is used to dissolve contaminates such as metal oxides from the gold. The flux is added to a crucible with the gold that is then melted in a furnace. You can make flux for gold refining
In most instances if you are just handling a few gold Quartz specimens that you find here and there, the use of mercury will not be worth your time. In some cases the gold in the ore is extremely fine sized, and using mercury to capture it makes sense.
In many countries, elemental mercury is used in artisanal and smallscale gold mining. Mercury is mixed with goldcontaining materials, forming a mercurygold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury

The recovery of gold from Charters Towers type ore requires a relatively simple metallurgical process using wellestablished methods and equipment. Citigold''s main gold recovery tool, the Black Jack gold plant, is an industry standard carboninleach (CIL) plant.
Recovering fine gold from black sands is one of the most challenging aspects of gold mining. While we are all hoping to find that onceinalifetime gold nugget, the vast majority of gold that we find as prospectors is very small in size, ranging from gold flakes down to dust so small that it is nearly invisible. Extremely fine particles of gold like this can be very difficult to separate from
