Volcanogenic massive sulfide ore deposit - Wikipedia

Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments. These deposits are also sometimes called volcanic-hosted massive sulfide deposits. The density generally is 4500 kg/m3. They are predominantly stratiform accumulations of sulfide

Sulphide Gold Ore Treatment by Leaching and Flotation

18/04/2016  The concentrate from either plant could be roasted for the elimination of high cyanide consuming arsenic from arsenopyrite ores. The calcine is then quenched, ground and returned to the plant. In fact, flotation has made possible the treating of such ore bodies for the recovery of gold. It was never possible to treat these direct by cyanide and difficult to roast ore alone because of the large

Review of the hydrometallurgical processing of non-sulfide ...

01/10/2014  The most appropriate route for processing non-sulfide ores is the use of hydrometallurgical acid-leaching, solvent extraction, and electrowinning technology. The Skorpion Plant, which uses this method to recover zinc metal from zinc silicate ores, is definitely one of the most economical methods in terms of operating cost. A common problem in non-sulfide zinc deposits is the

Rebellious Ores: Sulfides, Selenides and Tellurides

In many locations where they had initially been recovering 90% of the assay values processing oxidized surface ore, with the rebellious sulfide ores they were recovering less than 50%. The rest of the precious metals in their ore simply flowed uselessly out from the mill and into the tailings pond. Many rich and profitable mines suddenly became money losers when the miners got down to those unoxidized, primary ores

Sulfide - Wikipedia

Corrosion is a major concern in many industrial installations processing sulfides: sulfide ore mills, deep oil wells, pipelines transporting soured oil, Kraft paper factories. Microbially-induced corrosion (MIC) or biogenic sulfide corrosion are also caused by sulfate reducing bacteria producing sulfide that is emitted in the air and oxidized in sulfuric acid by sulfur oxidizing bacteria.
