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.

Extracting copper from its ores. the method used to extract copper from its ores depends on the nature of the ore. sulfide ores such as chalcopyrite (\(cufes_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores. chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of.
Most of the sulphur in chalcopyrite turns into sulphur dioxide (so 2). the reaction of these processes can be written as: 2cufes 2 2sio 2 4o 2 → cu 2 s2fesio 3 3so 2. the copper extracted from this process is mixed with the slag and is called matte copper due to its texture and appearance.

Removing the goldbearing 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.
