Mineral Sands Process Development

6 | ALS Metallurgy - Mineral Sands Process Development Heavy Liquid Separation This type of gravity separation is also known as “sink-float” separation. The heavier particles will sink and effect sharp separation of the heavy and light particles. In practice, the dense media (i.e. bromoform at 2.84-2.89, tetrabromomethaneSpiral Concentrators — IMSC Group,Principle of Separation. Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral trough.Heavy Minerals Processing Plant Design, Machine & Install,,After gravity separation the concentrate contains those heavy minerals and some other impurity minerals. Flotation: Flotation is used to separate the target minerals from others like quartz, sericite, tungstite, sillimanite, etc. Magnetic separation: Magnetic separation is mainly used for separating magnetic mineral, such as magnetite, ilmenite,Gravity separation process - Mineral Processing Plant,,Gravity separation process is the earliest method that applied in mineral processing.
