Some impurities form a slag such as FeO.SiO 2 , which floats on the surface of the liquid like oil on water and is easily removed. Courtesy of Xstrata. The smelter for sulfide produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching from oxide ores.

The test is a kind of relatively high grade of sulphide -lead , the difficulties of test is the effective of and lead, the lead grade of 13.08% and grade of 1.33% in comprehensive core sample. After the exploring test of principle flow sheet, the flotation process of depress lead and float is used.

is an example of this. mostly occurs as sulfide , which are heated in air to convert them to II oxide. Molten can be produced from oxide by heating with carbon:

The principal of is pyrite and is extracted from this . The different steps in extraction of are: Crushing and Concentration: The obtained from mines are broken down into small piece by jaw crusher and then pulverized. The being sulphide is concentrated by froth floatation process.

A typical might contain 0.085 percent silver, 0.5 percent lead, 0.5 percent , and 0.3 percent antimony. After flotation , the concentrate would contain 1.7 percent silver, 10 to 15 percent lead, 10 to 15 percent , and 6 percent antimony.

The major steps in the extraction of are. in is reduced to sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag. Iron in is removed as iron silicate slag. Most of the sulphur in turns into Sulphur dioxide SO 2 .

The process used to treat sulfide begins at the mine site, where the -bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of increases as the is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
