Ore washing is an integral part of the entire mining process . Washing is scrubbing with water or mechanical force is more clay cement or clay ore , the ore broken loose , wash down the surface of fine clay and ore separation process. This article details the process of washing the ore .Washing is mainly characterized by viscosity material separation process. The whole process generally includes two broken loose and separation steps. Crumbling is soaked by water shock and stirring clayey material crushing and dispersion ; separation is to borrow the role of water suspended in the water clayey fines and slimes and coarse material apart. For some materials , and separation of granular two steps are carried out separately ; However, for most materials , and separation of granular almost the same time , as long as these two steps and including the coarse and fine or mineral derived mud products operations and processes that can be referred to washing .
Ore washing is the most widely used as a preparation before sorting operations , placed chosen ( including hand-selected and optoelectronic election ) , broken, re-election ( including heavy media beneficiation ) , magnetic separation and flotation before . Aimed at eliminating the slime on the impact of these operations and the hazards in order to improve the conditions of these operations , improve efficiency and get a good job sorting index . Such as when dealing with alluvial tin , separated by a wash method coarse ore mine waste rock without the resulting fine particles off the mud and then by selected part , you can reduce the amount of processing . Tungsten ore mined underground , although not a lot of mud , but in order to hand the election or opto -election for easy identification , often also need to wash mine . Some ore containing more than mud , pre- washing method using mineral mud and mineral blocks apart , to avoid clogging during operation crusher, screening machine and ore bin and other equipment. Some native ore mineral mud and mineral blocks optional on ( such as flotation , magnetism , etc. ) are very different , after washing the mud, sand separated dealt with separately , you can get a better sorting index .
Washing can also be used as an independent student . As some talus or eluvial heavily oxidized hematite , limonite, manganese ore, containing the clay mineral cements little after wash mine tailings discarded as a final , lump ore can be obtained as the final product application . Natural silica sand, clay and kaolin for industrial use and some phosphate rock , usually only need to wash mine, plus screening ( or grade ) can get qualified products.
