Silver mining is the extraction of the precious metal silver from the Earth through excavation (i.e., mining ). Silver is found in a native form very rarely as nuggets in placer deposits and veins. It is more commonly combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S ), chlorargyrite ("horn

Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer.

available due to insufficient technology. The silver yield from ore currently ranges from 40 % to 65 %. In a projection of the current increasing rate of mining, all silver would be harvested in about 17 years. After this, there will be only one source of silver, and that is from recycling processes (Dias, 2016).

Toxic chemicals are used in the Flotation Process to separate the copper and molybdenum out of the milled powder. This Flotation process is the major extraction method at Duval/Sierrita mine because of the poor quality of the copper at this site. Some chemicals produce bubbles that that the copper adheres to and the "bad stuff" falls to the bottom.

Chemicals used in mining and processing minerals contaminate the land, water, and air, causing health problems for workers and people living near mines. Toxic chemicals used in mining include: cyanide, sulfuric acid, and solvents for separating minerals from ore. nitric acid. ammonium nitrate and fuel oil (“ANFO”) used in blasting tunnels.

Processing From Brine Much of the lithium produced today is extracted from brine reservoirs called salars that are located in high-elevation areas of Bolivia, Argentina, and Chile. In order to extract lithium from brines, the salt-rich waters must first be pumped to the surface into a series of large evaporation ponds where solar evaporation occurs over a number of months.

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.

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 mining declined in 1870 due to devaluation that occurred when the United States switched to the gold monetary standard. Although by 1810 Chile was producing 19,000 m.t./yr of copper from oxidized ores, copper mining did not dom-inate until 1840, when reverberatory furnace technology was introduced to process sulfurous ores.
