Silver ores - Danafloat

The most common silver-bearing minerals recovered by flotation are argentiferous galena, native silver, argentite (Ag2S) and tetrahedrite (Cu,Fe,Ag) Sb4S3). Often these minerals float with the base metals such as copper and lead sulphides or are the primary target mineral (tetrahedrite).

Silver Gold Recovery Flotation Process

Mar 17, 2017  A total recovery of more than 97% of the gold and silver is made by flotation, while the combined flotation-cyanidation process gives an overall extraction of 95%. The installation is much more compact and its capital cost far less than one embodying fine grinding and cyaniding of the whole tonnage, and it can be run with lower operating ...

Silver - Wikipedia

Silver is a chemical element with the symbol Ag (from the Latin argentum, derived from the Proto-Indo-European h₂erǵ: "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. [citation needed] The metal is found in the Earth's crust in the pure, free elemental ...

Silver: A native element, mineral, alloy, and byproduct

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

Copper Mining and Extraction Sulfide Ores

From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air.
