Flotation is a method that is widely used in gold ore processing plant to process the rock gold ,commonly used in dealing with highly floatable sulfide minerals containing gold ore. Flotation process can maximum enrich gold to the sulfide mineral , tailings can be abandoned directly , the cost of processing plant is low, 80% of China's rock gold are used in this method. Flotation process that mainly including dosing, mixing, filling, blowing foam etc .
Copper ore divides into ore sulfide ,ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation , for refractory mixed copper ore and refractory oxide ore , normally use hydrometallurgy process .
Scheelite dressing can use gravity, magnetic and flotation separation. The types and properties of the ore decide the separation methods and processes. Basing on good floatability of scheelite, the flotation is selected.
Nickel ore divides into copper sulfide and copper oxide ore , the main process for copper sulfide is flotation , magnetic and gravity separation is the subsidiary process .
Gravity separation is the mainly process for chrome processing ，sometimes the chrome concentrate will be separated by low intensity magnetic separation or high-intensity magnetic separation for a second processing , that`s to improve the grade of the chrome .Several ores can use flotation or flocculation flotation process .
Pb-Zn ore divides into sulfide Pb-Zn ore and oxide Pb-Zn ore . Flotation is the most widely used in separating sulfide Pb-Zn ore , to separate zinc and plumbum , sometimes for separating sulfide iron and other minerals . Sulfide Pb-Zn ore process divides into priority flotation process , mix-separating flotation , asynchronous flotation ,and so on .
According to different phosphorus ore property, phosphorus ore separating process have flotation, scrubbing desliming, gravity separation, chemical leaching, combined separating, photoelectric selection, magnetic coating, etc. the flotation is most applied, including direct flotation, reverse flotation, direct-reverse flotation and double reverse flotation.
In Current years, Tailings dry discharge is a gradual emerging new tailings treatment process. It means the tailing pulp from dressing plant through multi concentration, then use dewatering vibrating screen to treat and get low moisture, easy sediment solidify and good for stockpiling slag. Slag can be transport to fixed position for dry stockpiling.
