Definition, Physical,,It was the traditional method of concentrating ore directly with hands. In this method, the gangue or adhering solid matrix is separated from the ore with a hammer’s help. The separation and identification of gangue are made based on the differences in colour or lump shape. Hydraulic washing. It is also called “Gravity separation” or,Kaolin Purification,Gravity Separation,Magnetic Separation,,2.Kaolin Magnetic Separation. Almost all kaolin raw ore contains a small amount of iron minerals, generally 0.5% -3%, mainly including colored impurities such as magnetite, ilmenite, siderite, and pyrite. The magnetic separation method mainly uses these magnetic differences between gangue minerals and kaolin to remove these colored impurities.Major Mines & Projects | Direct Shipping Ore (DSO) Mine,The run-of-mine ore processing consists of crushing and wet screening to reduce the ore to - 6 mm size. Gravity separation methods, employing jigs, spirals and hydro-classifiers, are utilized to upgrade coarse fractions.
