No mining industry uses sulfuric acid. Some of the milling processes to recover the mineral from the ore may use a little, but since the most frequent and most difficult problem with extraction is finding the best and cheapest way to reduce a ...
The papers in this issue focus on sulfuric acid. Sulfuric acid has become an integral part of the mining industry and today there are more sulfuric acid plants operated in the mining industry than in the chemical industry in South Africa. This revolution took place in the 1950s with the advent of the uranium extraction and recovery process.
Sulfuric acid has many industrial purposes and is produced in greater quantities than any other chemical worldwide. In metal mining, sulfuric acid is used to leach copper oxide minerals. In one process, a solution of sulfuric acid laden with copper sulfate is stripped of copper via a solvent extraction and electro winning with the used sulfuric ...

Aug 07, 2010· sulfuric acid from gypsum CaSO4 Also, came up with an industrial process for producing sulfuric acid from common and inexpensive gypsum (CaSO4). An old chemistry book I had said that scientists couldn''t find a commercially viable process for turning this potential resource into the highly useful acid product.
This element is used in the preparation of sulfuric acid. It is mostly used in the industries for steel and rubber making purposes. It is also used for producing inorganic chemicals, matches, fumigants and glass. It is also used in explosives, cement, animal feed and adhesives. The element can be found in many natural resources.

Potential Phosphogypsum Uses. Phosphogypsum is a byproduct of the chemical reaction called the "wet process," whereby sulfuric acid is reacted with phosphate rock to produce the phosphoric acid needed for fertilizer production. There are approximately five tons of phosphogypsum produced for every ton of phosphoric acid produced.
Phosphogypsum, however, is slightly more radioactive than natural gypsum. The radium that is found naturally associated with phosphate rock becomes associated with the phosphogypsum after the rock is reacted with sulfuric acid. The EPA prohibits the use of .

The reaction between sulfuric acid and lime to form gypsum takes minutes. S + Thiobacillus + warm and wet soil = H2SO4 (sulfuric acid) H2SO4 + CaCO3 (lime) = CaSO4 (gypsum). Lime is insoluble in water. Gypsum is soluble in water. Besides sulfuric acid, phosphoric acid can be used .
Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related the form of γanhydrite (the anhydrous form), it is used as a particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral has many uses in industry. All forms are white solids that are poorly soluble in water.
Small amounts of anhydrite are used as drying agents in plaster, paint, and varnish. It is also used along with gypsum to produce plaster, joint compound, wallboard, and other products for the construction industry. Anhydrite has also been used as a source of sulfur in the production of sulfuric acid. Synthetic Anhydrite

In 2010, the United States produced more sulfuric acid than any other inorganic industrial chemical. The principal use for the acid is the extraction of phosphate ores for the production of fertilizer manufacturing. Other applications of sulfuric acid include oil refining, wastewater processing, and mineral extraction.
