Gold processing - Mining and concentrating | Britannica

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

Extraction of gold using cyanide - Home » NZQA

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

Bodie, California | The cyanide leaching process

Once the fine rock went through this method, the gold and silver was usually so small, it wasn't cost effective to try to extract it. The remainder was dumped into large piles (these piles were called 'tailings') and left as a by-product of mining. Then the "cyanide leaching process" was developed.

Extracting Gold | HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Which process uses cyanide to extract gold? - Brainly.com

Dec 14, 2017· Answer: The answer is Leaching.. Explanation: The cyanidation of gold is a metallurgical technique for the extraction of gold from low quality ore, which seeks to convert gold (insoluble in water) into complex metal anions of aurocyanide (soluble in water) through a process called leaching, which is a process in which a liquid solvent passes through a pulverized solid so that the dissolution
