Magnetic Separation For Ore Dressing And Metallurgy
There are many methods of separation (concentration) of minerals 1) Gravity separation. There are than 12 types of gravity separation of minerals. It is used for the extraction of gold, coal, cassiterite, wolframite, rare earth mineral, niobium, zirconium, uranium minerals, and others. . 2) Magnetic separation. There are than 14 types of magnetic separation of minerals.The magnetic fraction may be valuable or gangue depending upon its use in a particular flow sheet or process and so also the non magnetic fraction, e.g., separation of magnetite (magnetic) from quartz (non magnetic), separation of tin bearing mineral cassiterite (non magnetic) from magnetite (magnetic) impurity etc.
