Silver element extraction methods GREAT MINING

Silver element extraction methods GREAT MINING

SILVER ORES : Even though certain silver bearing ores contain silver, none of them contain silver as their major constituent. A distinct ore might contain 0.085 percent silver, 0.5 percent lead, 0.5 percent copper, and 0.3 percent antimony and after flotation separation, the concentrate would contain 1.7 percent silver, 10 to 15 percent lead, 10 to 15 percent copper, and 6 percent antimony.

Silver Chemical Element reaction water uses elements

Silver Chemical Element reaction water uses elements

Chemical properties Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. It does react slowly with sulfur compounds in the air, however. The product of this reaction is silver sulfide (Ag 2 S), a black compound. The tarnish that develops over time on silverware and other silver-plated objects is silver sulfide.

Oscillating Chemical Reactions Inside Mines

Oscillating Chemical Reactions Inside Mines

Oscillating reactions are among the most fascinating of chemical reactions. In one type of reaction, a mixture of chemicals goes through a sequence of color changes, and this sequence repeats periodically. In another, the mixture periodically emits a burst of gas, foaming up. To many, oscillating reactions are engaging examples of chemical magic.

Silver A native element mineral alloy and byproduct

Silver A native element mineral alloy and byproduct

Native silver is sometimes found in the oxidized zones above the ores of other metals. It persists there because silver does not readily react with oxygen or water. It does react with hydrogen sulfide to produce a tarnished surface that is composed of the silver sulfide mineral known as acanthite.

Silver processing Britannica

Silver processing Britannica

Silver is removed by the Parkes process, which consists of adding zinc to the molten lead bullion. Zinc reacts rapidly and completely with gold and silver, forming very insoluble compoundsthat float to the top of the bullion. These are skimmed off and their zinc content recovered by vacuum retorting.
