Although the quantities of gold and silver in the Earths crust are small, their existence has been known since ancient times. This is due to their precious character, their purity and the fact that they can be extracted from ore at a relatively low temperature. Since antiquity these metals have been used to produce jewelry and coins.
Apr 12, 2017 It is noted that for gold and silver ores shipped in the crude state or in the form of concentrate (first six mines listed), the net return to the shipper varies from about 54 to 84 percent of gross value at full quoted prices whereas at the Vulture mine, where the gold and silver are shipped as high-grade precipitate, the net return is 92.7 ...

Gold ores are classified free-milling and refractory based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an
Jan 01, 2016 The chemistry of leaching gold and silver from their ores is essentially the same for both metals, and many ores contain a mixture of the two. A dilute alkaline solution of sodium cyanide dissolves these metals without dissolving many other ore components (copper, zinc, mercury, and iron are the most common soluble impurities).
