Gold processing, preparation of the ore for use in various gold is the most common mineral of gold, accounting for about 80 percent of the metal in the earths occasionally is found as nuggets as large as 12 millimetres inch in diameter, and on rare occasions.
Ing water and grinding the ore in large popular method is autogenous grinding, which means that the ore grinds itself without the addition of external grinding end result is a slurry containing water and finely ground the flotation process is a surfacechemical process, where small amounts of chemicals.
Iron ore is converted into various types of iron through several most common process is the use of a blast furnace to produce pig iron which is about 9294 iron and 35 carbon with smaller amounts of other elements.
Typically, mill tailings range from sand to siltclay in particle size 40 to 90 percent passing a mm sieve, depending on the degree of processing needed to recover the basic mineral processing techniques involved in the milling or concentrating of ore are crushing, then separation of the ore from the impurities.
Corrosion, they appear to play only an indirect role in the rate of corrosion after primary ratecontrolling factors are the availability of oxygen, the electrical resistivity and relative humidity of the concrete, and the ph and types and causes of concrete deterioration salts are a major.
