Clay minerals are one of the most utilized minerals among non-metals. These are hydrous aluminum silicates with a layer (sheet-like) structure. Kaolin is a hydrous aluminosilicate mineral with a thin platelet structure. Kaolin is extensively used in paper, paint, and many other industries. Wet processing of kaolin will not be sustainable over the long term …

beneficiation method is not economical, low-produc-tive, requires large consumption of water and sedimen-tation devices with a large area. The purpose of kaolin raw materials beneficiation process is to increase the content of valuable clay rocks (kaolinite, halloysite, diquite), reduce the amount of quartz, iron and other ore minerals.

Oct 1 2014. The beneficiation process can be defined as a treatment process of ore which results in a more concentrated form of the product. It is often used in the preparation of iron ore for smelting. This is an essential process as it helps improve the yield from a deposit of ore, thereby increasing the potential profits that can be obtained ...

after the dry beneficiation. CuO remained unchanged after the wet beneficiation whereas it was completely eliminated after the dry beneficiation. This was likely because the CuO impurity was from the silt or/and the quartz component of the raw kaolin which were more effectively removed during the dry beneficiation than during the wet beneficiation.
