초록

A method is disclosed for separating titaniferous and ferruginous discolorants from a crude kaolin clay. A dispersed aqueous slurry of the clay is formed containing a deflocculant and a fatty acid collecting agent, and the slurry is conditioned to coat the discolorants with the collecting agent to thereby render the discolorants hydrophobic. A system of sub-micron sized magnetic ferrite seeding particles, the surfaces of which have been rendered hydrophobic, is thereupon added to the slurry. The seeded slurry is mixed to coalesce the hydrophobic-surfaced...

A method for producing a low-abrasion, high brightness calcined clay from a crude kaolin clay containing titaniferous and iron-containing discolorants, comprising the steps of: forming a dispersed aqueous slurry of said clay, containing a deflocculant, and a fatty acid collecting agent; and conditioning said slurry to coat said discolorants with said collecting agent, to thereby render same hydrophobic; adding to said slurry a system of sub-micron sized magnetic ferrite seeding particles, the surfaces of which have been rendered hydrophobic; mixing said ...
