In both methods, gold and silver is accumulated in the cyanide leach solution. The gold and silver bearing liquid, called pregnant solution, is separated from the ore by various drainage and filtration processes. The most common methods to remove the gold and silver involve activated carbon, or zinc precipitation.
Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores.
How is iron obtained from its ore? Iron ore consists of the element iron combined with other elements, mostly oxygen. During smelting, the iron ore is heated with carbon. The carbon combines with the oxygen and carries it away, leaving iron. Carbon was originally obtained from charcoal derived from wood, but in the early 1700s furnaces began to ...
Sep 19, 2014· Extracting Platinum from these ores is arguably one of the most capital and labour intensive operations in the world. On average, it takes up to six months and up to 12 tonnes of ore to produce an industry standard troy ounce, which is grams of pure metal.
used on a commercial scale for the extraction of titanium. Metals below Carbon in the Reactivity Series. A metal below carbon in the reactivity series (zinc to silver) may be extracted by heating the metal ore with carbon. During the reaction, the metal in the ore is displaced from its nonmetal anion because carbon is more reactive than the metal.
Most of the silver produced today is a byproduct of mining copper, lead, and zinc. The silver occurs within the ores of these metals in one of two ways: 1) substituting for one of the metal ions within the ore mineral's atomic structure; or, 2) occurring as an inclusion of native silver or a silver mineral within the ore .
