METHOD FOR PRODUCING HIGH OPACIFYING KAOLIN PIGMENT
A method of producing a high opacity paper filler pigment which comprises subjecting an iron-stained titania-containing kaolin to beneficiation by froth flotation or high intensity magnetic separation; recovering the froth or magnet rejects, dewatering and drying the rejects to produce a kaolin enri...

| description | A method of producing a high opacity paper filler pigment which comprises subjecting an iron-stained titania-containing kaolin to beneficiation by froth flotation or high intensity magnetic separation; recovering the froth or magnet rejects, dewatering and drying the rejects to produce a kaolin enriched in titania, and calcining the same at a temperature in the range of about 1500.degree. to about 2200.degree.F. |
