At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite CuFeS the formula, it is clear that iron and sulphur have to be removed in order to produce copper.
One reaction that takes place is: 2CuFeS 2 (s) + 3O 2 (g) 2FeO(s) + 2CuS(s) + 2SO 2 (g) As SO 2 is hazardous, it has to be removed from the gases released into the environment. One way of solving the problem is to convert it to sulfuric acid. This is either sold for industrial use or used to extract oxide ores of copper by leaching.
#0183;#32;Explosives are used in the mining of many metals but not usually in mining coal. The material being sought as well as the material that is considered waste determines the chemical reactions being used at the mine to process the ore. I guess I am trying to say that you have posed an open ended question that could take years to answer.
#0183;#32;My science teacher set us hw where we have to find a chemical reaction used in industry. We have to say the equation and what it is used

The metals mining industry accounts for 40% of total disposal or other release of TRI chemicals. 6 out of 88 reporting facilities initiated practices to reduce their toxic chemical use in 2012.
#0183;#32;The main chemical groups divided by application are collectors, which act as surfactants in the flotation cell and adsorb to the surfaces of the valuable mineral particles and make them hydrophobic (water repellant) and frothers, which have the effect of producing stable bubbles in the cell for these hydrophobic particles to attach themselves to.

The chemical reactions taking place in your swimming pool; but the strategies have yet to be adopted on a large scale because the mining industry sees economics as the bottom line, Zobrist
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents
Cyanide has been used for gold mining for more then 100 years. If not used properly it can be deathly. When ingested or inhaled can cause death within 1060 min. There are no other alternatives for cyanide. cyanide can be bad for the environment . There are problems with the
#0183;#32;Sulfuric acid. 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.

Ten Important Chemical Reactions 1. Synthesis of ammonia. Reaction: 3H 2(g) + N 2(g) 2NH 3(g) Hydrogen gas and nitrogen gas are combined in the presence of a catalyst at high temperature and pressure to produce ammonia gas. Significance: Synthesis of ammonia leads to the production of fertilizer (ammonium nitrate) and to the production of
Chemicals Used in Mining Hesperian Health Guides
#0183;#32;Chemical reactions are common in daily life, but you may not recognize them. Look for signs of a reaction. Chemical reactions often involve color changes, temperature changes, gas production, or precipitant formation. Simple examples of everyday reactions include digestion, combustion, and cooking.
When mining begins, chemicals are leaked into the ground and water, contaminating everything. Not to mention the fact that if chemicals get into the water shed, it can affect thousands of people, plants, and animals. Why are These Reactions and Cyanide Used? Cyanide is used in the process of separating the gold and silver particles from the ore.
