Gold mining describes the process of extracting ore – metalrich rock – from the earth's crust. And, as with other minerals, there are a number of geological processes that are involved in forming these ore deposits. Modern gold mining predominantly takes place in areas where there is a significant concentration of goldbearing ore (ore body).
Increase Your Yield Through Chemical Extraction of Black Sands. If you feel that your black sand mining operation is losing micron gold after free gold has been removed, that your magnetics have precious metal bearing material that you cannot capture, or that your sands contain sulfide material that may contain precious metals,...
Apr 24, 2017· Gold Refining Techniques. Gold refining, or parting, is used to separate gold from impurities and other metals, such as silver. Gold and silver, which are often extracted from the same ores, are chemically similar, making them difficult to separate. Before the advent of processes to separate silver and gold, a goldand silver alloy called electrum...

May 08, 2007· A great deal of the silver from the goldsilver siliceous ores is obtained with the gold by cyanidation, the silver being recovered by refining the mill bullion. The remainder is obtained by smelting rich ores and refining copper or lead bullion produced.
The business of gold and silver refining, as it relates to doré treatment, is described and the processing routes for high and lowgold doré are provided. The processing methods for gold and silver refining comprise two main flowsheet configurations: prerefining followed by electrorefining and dissolution followed by precipitation.
Unlike alluvial gold, which is found as very small flakes on river banks, goldbearing rocks have to be dug out of the ground. We want pure gold, but goldbearing rocks include lots of other materials such as quartz, calcite and the sulfides of other metals.

This is a concern because Arsenic is actually very common in many gold ores. Selenium, mercury and other toxic elements are also found in many high sulfide gold and silver ores as well. To roast sulfide ores, it takes a good red heat and a good amount of air, but not too hot as you don't want to melt them.
Goldbearing ore of sedimentary origin containing organic carbonaceous material and goldbearing sulfides is treated to increase the recovery of the gold content thereof by standard cyanidation practice.
