Silver Facts, Symbol, Discovery, Properties, Uses

Silver (pronounced as SIL-ver) is a shiny metal denoted by the chemical symbol Ag. Though it is not highly reactive, it gradually tarnishes in air to form a black coating of silver sulfide. It has 35 isotopes with mass numbers ranging from 94 to 128 of …

Colonial Silver Mining: Mexico and Peru

C olonial silver mining began when European techniques of production were introduced into the New World to satisfy the sustained European demand for precious metals. At first the industry formed little more than an overseas extension of the great central European mining boom of the years 1451-1540. Certainly it was then that an association of high capital investment with a …

Cyanide Use in Gold Mining

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;
