subject: Iron Ore Beneficiation Sales In South Africa [print this page] Equipment employed in the Iron Ore Beneficiation method
Iron ore beneficiation plant or ore processing plant is employed to beneficiate a large kind of industrial iron ores. during this application the comparatively massive volumes of non-magnetic materials are sometimes the business merchandise. the number of magnetic materials removed is sort of little, and dry separation is that the general rule. Iron ore processing plant is additionally necessary in processing phosphate, titanium, chrome, manganese, tungsten, molybdenum, nickel, niobium and tantalum ores.
Magnetic separation of iron ores is one amongst the fastest-growing segments of the minerals beneficiation business. The tonnage of taconite ores processed annually by magnetic separation zcill, in an exceedingly few years, reaches one hundred million.
Magnetic separation occupies a lovely position within the field of ore beneficiation. this sort of beneficiation originated in 1792, when William Fullarton was issued a British patent covering the separation of iron ore by magnetic attraction.
5. Stripping the metals from the carbon by acid laundry and circulation of a caustic cyanide solution;
6. Precipitation of the gold and silver by electro-winning;
7. Smelting of metal product into bars;
8. Pumping of the barren slurry (tailings) to the tailings storage facility.
Ore beneficiation technology
(1) Magnetite dressing technology
It is mainly used for Ore separating line with low style. as a result of the rocks have a robust magnetism and simple to grinding, most of the magnetic ore-dressing plants adopt one stage and lots of stages method for its crushing and grinding. Later, our country independently researched and developed eternal magnetization technology for the magnetic separator. once the Sixties, the new technology of fine screening and grinding once more makes the concentrate grade improve to concerning sixty six from sixty two, so realizing the necessity by the Ministry of Metallurgical trade that the concentrate grade must be improved to sixty fifth.
This kind of rocks have difficult part and diversified sorts, in order that the ways, equipment and production method are totally different. for instance, In Panzhihua, plants there gained concerning fifty three ferrovanadium concentrate through magnetic separation, and therefore the gangue is disposed through light-weight porcelain scavenging, double beneficiation, flotation and drying electricity choice and within the finish, titanium and cobalt concentrate are gained.
