· The carboninpulp process is used to treat low grade gold and/or silver ores. The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device. This is done to produce a feed suitably sized so that subsequent leaching is rapid.

Concentration of Ores. An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores ...

· First, use an ammonium thiosulfate solution which is recycled at a temperature of 1525°C to process silvergold ore. Second, the filtrate produced after dissolution is electrolytically extracted with a high alloy electrode at a current density of 200...250 A/m 2 until the electrolyte reaches a concentration of 515 ppm Au, 1100 ppm Ag and g/1 Cu.

The ore is transported 40 kilometers to the Pirquitas processing facilities, which produce a silverlead concentrate and a zinc concentrate that are shipped to international smelters. The Pirquitas processing facilities have been in commercial production since 2009, processing ore from the San Miguel open pit, which concluded mining activities in January 2017 and currently hosts the tailings ...

Silver is a soft, white metal that usually occurs in nature in one of four forms: 1) as a native element; 2) as a primary constituent in silver minerals; 3) as a natural alloy with other metals; and, 4) as a trace to minor constituent in the ores of other metals. Most of the silver produced today is a product of the fourth type of occurrence.

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.

The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing: processing by fire. (Courtesy of Xstrata.) The smelter for sulfide ores produces sulfur dioxide gas.

Processing. At the surface, the ore is subjected to additional crushing and fine grinding. A flotation process is used to separate the silverbearing galena and tetrahedrite from other ore minerals and waste rock particles (tailings) to form mineral concentrates. Development of the flotation process occurred in the early days of mining at ...
