Silver mining is the resource extraction of silver by mining.. Silver is found in a native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite Ag 2 S , chlorargyrite "horn silver," AgCl , and galena a lead ore often containing significant amounts of silver .
Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made.
Silver processing, preparation of the ore for use in various products. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen. The lustre of the pure metal is due to its electron configuration,
Silver Mining Process . Silver is mined using a number of processes. One of the most common processes of extracting silver metal for the ore is the heap leach or cyanide process. The process is most popular with many miners because it is low cost, especially when processing low-grade ores.
Relation to Mining. Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite Ag2S, silver sulfide . Silver is commonly extracted from ore by smelting or chemical leaching. Uses. Silver has been used for thousands of years for jewelry and decorative items of all types.
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.
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& 39;s atomic structure; or, 2 occurring as an inclusion of native silver or a silver mineral within the ore mineral.
The two types of silver, silver 1 and silver 2 cannot be distinguished, visually, from "normal" silver unless the latter occurs as wires. The Cobalt-Gowganda camp produced some 600,000,000 ounces of silver and huge masses of the mineral were encountered and recorded during mining.
