How is gold found and extracted from mines?

The process behind gold extraction and refinement. The gravel is then placed in rotating drums that have steel balls inside which grind the gravel into a powder. Water is then added to the powder to produce a pulp, which is run through a series of leaching tanks.

Gold extraction

When the gold contains platinum and related metals, it is submitted to further refining. Part of the platinum is dissolved out by the treatment with nitric acid. Iridium was formerly slagged off by fusion with potassium nitrate, but all the platinum is simultaneously slagged, and can be recovered only by a cumbrous process.
