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 ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores.
The majority of the sulfur produced in the United States is used to make sulfuric acid. Sulfuric acid has multiple uses in the production of chemicals, petroleum products and a wide range of other industrial applications. Sulfurs main use is in making chemicals for
The concentrator contains a separate circuit for recovery of copper from the on-site smelter slag. Slag can contain between 8 and 10% Cu and is sent to its own process line containing a SAG mill two ball mills, and floatation circuit The Chuquicamata mines smelting process involves two stages a smelting stage and a conversion stage.

Mar 13, 2019 As follows from curves (Fig. 2) in the first 20 min there is intense transfer of iron from slag into solution for all of the three specimens, and then the process slows down in view of solution saturation with iron and inadequate sulfuric acid. An increase in the degree of slag metallization facilitates saturation of the solution with iron (Fe 2).
A process for preparing ferrous sulfate includes such steps as reaction between waste dregs containing 3-valence Fe and sulfuric acid at 80-130 deg.C to obtain acidic solution of iron sulfate, adding troilite or sulfur ore concentrate to obtain ferrous sulfate solution, cooling to -10-20 deg.c for crystallizing, filtering, centrifugal drying and baking to obtain FeSO4.7H2O.
