Iron removal from kaolin. Comparison between “in situ”

2003-2-1  Kaolin is basically composed of kaolinite and moscovite. Iron is present as magnetite and as amorphous oxides and hydroxides (analysis performed by RX diffraction, model D5000, Siemens). The amount of removable iron by a leaching process was determined by treatment with sodium dithionite for 1 h at 40 °C; washing the residue with 0.02 M HCl.

The Removal of Iron From Hard Pulverised Kaolin by Dry ...

Deposits of hard kaolin are abundant in China, with kaolin content in the ore exceeding 95%. It is, however, rather difficult to remove iron from the ore. It was demonstrated that wet high–gradient magnetic separation is very efficient in removing the iron compounds from kaolin. For hard kaolin, however, dry high–gradient magnetic separation (HGMS) may be more suitable.
