Manganese ore processing technology is based on its different principles , there are many methods , now in China magnetic concentration is the most widely used in manganese ore processing technology , after rough concentration and selected concentration then get the concentrate .
Magnetic process is suitable for high phosphorus 、high silica、low iron manganese ore .
1. Strong magnetic rough separation : wipe out the waste by using strong magnetic separator that specialize using in manganese ore , rough concentration of the concentrate by using spiral classifier , rough concentration of the tailings drain to tailings thickener directly .
2. Classification : underflow from the classifier is transported to magnetic separator for concentration , the overflow will be concentrated by thickener .
3. Middle magnetic separation : the tailings from middle magnetic separation drain to concentrator , the concentrate from middle magnetic separation get together with underflow of the concentration .
4. Purification and concentration,concentration overflow return to system for cycling , concentration underflow get together with concentrate , to be the final separated concentrate .
