PURIFICATION OF KAOLIN CLAY BY FROTH FLOTATION -

Flotation was carried out in a batch laboratory cell for 10 minutes. The underflow (machine discharge product or "MD-1" ) of the flotation cell containing the partially purified clay was weighed to ascertain yield of the rougher flotation. The froth from the rougher flotation was diluted and cleaned by reflotation for 10 minutes.
