Limonite is present as an amorphous clay coating surrounding other minerals with high iron content. It was also noted that the kaolinite that is present has varying iron content (from 4% to 16%). ... Special focus has been given on the selection of beneficiation processes routes based on mineralogy for processing of low-grade iron …
The process is not effective when the clay feed is too fine and is therefore limited to coarser applications (Smith, 1973). - The use of low resin acid tall oil which acts as a collector and also as a controlled frothing agent has been suggested to remove the colored imuri- ties from kaolin clay (Mallary, 1974).
