METHOD OF TREATING CLAY TO IMPROVE ITS WHITENESS |
摘要 |
<p>A method of treating a clay to remove therefrom titanium mineral impurities comprising the steps of mixing an aqueous slurry of said clay having a high solids content with an activator and a collector for the titanium mineral impurities; conditioning the aqueous clay slurry at said high solids content for a time sufficient to dissipate therein at least 25 horsepower hours of energy per ton of solids; adding to the conditioned aqueous clay slurry a polyacrylate salt deflocculant; subjecting the conditioned aqueous clay slurry undiluted containing the polyacrylate salt deflocculant to a froth flotation process and removing the titanium impurities with the froth; and recovering clay having a reduced titanium minerals impurities content.</p> |
