  • Sulfuric Acid Mining Health and Safety

    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 acid

  • Chemicals Used in Mining Hesperian Health Guides

    11/2/2020· Sulfuric acid is a toxic chemical used in copper mining. It is also a byproduct of many kinds of mining, mixing with water and heavy metals to form acid mine drainage. Sulfuric acid smells like rotten eggs. Contact with sulfuric acid can cause burns, blindness, and death.

  • What mining industries use sulphuric acid? Quora

    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 sulfur compound, sulfuric acid

  • Sulfur and Sulfuric Acid SpringerLink

    8/26/2015· Typical sulfur deposits occur in sedimentary limestone/gypsum formations, in limestone/anhydrite formations associated with salt domes, or in volcanic rock. 1 A yellow solid at normal temperatures, sulfur becomes progressively lighter in color at lower temperatures and is almost white at the temperature of liquid air.

  • Sulfuric acid Wikipedia

    In particular, "10M" sulfuric acid (the modern equivalent of chamber acid, used in many titrations), is prepared by slowly adding 98% sulfuric acid to an equal volume of water, with good stirring: the temperature of the mixture can rise to 80 °C (176 °F) or higher. Sulfuric acid reacts with its anhydride, SO 3, to form H 2S

  • SAIMM Sulfuric Acid

    The best and most profitable use of excess sulfuric acid was to make phosphoric acid. Since almost all phosphoric acid is made from apatite, containing calcium, the position is now that a great deal of the sulfuric acid made in the world today is ending up in small mountains of waste calcium sulfate, or phosphorgypsum, which is the better known name.

  • Uses of sulfuric acid Sulfuric acid uses like Sulfuric

    Sulphuric acid is an oily liquid that is viscous in nature. It is soluble in water and is a component of acid rain. The chemical formula of this compound is H 2 SO 4. It is mostly used in the production of fertilizers. Sulphuric acid gives rise to phosphoric acid which produces phosphate fertilizers.

  • Solution mining QueensMineDesignWiki

    The two main leaching agents for ISR projects are sulfuric acid or an alkaline leach. Both solutions provide similar chemical reactions through an ion exchange in order to leach the desired minerals. The largest factor between choosing a solution is the calcium carbonate concentration in the ore body.

  • Copper Mining and Extraction Sulfide Ores

    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. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace.

  • Acid Mine Drainage groundtruthtrekking.org

    Acid mine drainage (AMD) refers to the outflow of acidic water from a mining site. In most cases, this acid comes primarily from oxidation of iron sulfide (FeS2, also known as pyrite or "fool's gold"), which is often found in conjunction with valuable metals. Acid mine drainage is a major problem with many hardrock mines, including almost all mines where the metal ore is bound up with sulfur (metal sulfide
