Introduction to Mineral Processing - Chevron Phillips Chemical

The ability of a mineral to float depends upon its surface properties. Chemical modification of these properties enables the mineral particles to attach to an air bubble in the flotation cell. The air bubble and mineral particle rise through the pulp to the surface of the froth or that is present on the flotation cell.

differences - Is it "flotation" or "floatation"? - English ...

Some results for floatation and flotation with various related_terms are below. M = millions of hits. k = 1000's of hits. e.g. "Australia 420 k / 10.9 M" = 420,000 hits for floatation and Australia, 2.29 million hits for Australia and flotation.
