2017-5-1  To further investigate the effect of cyanide concentration on gold, silver and copper dissolutions, three levels of cyanide were added at a fixed initial glycine concentration of 10 g/L and pH 11.0. Gold, silver and copper extraction from these tests are shown in Fig. 13, Fig. 14, Fig. 15 respectively. Download : Download high-res image (137KB)

Escondida Mine, Chile NASA

2000-4-23  Primary concentrate of the ore is done on-site; the concentrate is then sent to the coast for further processing through a 170 km long, 9-inch pipe. Escondida is related geologically to three porphyry bodies intruded along the Chilean West Fissure Fault System. A high grade supergene cap overlies primary sulfide ore.

How to Process Copper Lead Zinc Ore with Gold and Silver

2016-4-27  The thickened concentrates (thickener underflows) are metered from the thickeners using Adjustable Stroke Diaphragm Pumps which feed the two Disc Filters. The lead-copper concentrate also contains the major part of the gold and silver values present in the ore. The high gold recovery possible by a flowsheet of this type is augmented by the Mineral Jig which recovers the coarse free gold.

How & Where to Sell Ore, Concentrates, and Bullion

2017-4-12  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 percent. Where the precious metals are shipped in the form of semi- refined bullion the return is often even higher. It is, therefore, decidedly to the advantage of the shipper to reduce gold and silver to bullion if his ore

Recovery of Gold as By-Product from the Base-Metals

2016-1-1  Gold is often associated with chalcopyrite in ore deposits, and efforts are therefore made at the mine to maximize the recovery of both gold and copper, either using a combination of gravity and flotation techniques or flotation alone. Using available techniques, some of the gold can be recovered directly as a gold concentrate, with, for example, gravity techniques in the grinding circuit, but usually significant quantities remain within the copper concentrate. Gold can be present in the copper concentrate as free gold
