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. Very obviously this method has methodological deficiencies, but it is also demonstrably useful.

Here potassium ethyl xanthate acts as a collector. $ce{KCN}$ and $ce{NaOH}$ depress the floatation property of $ce{ZnS}$ and $ce{FeS2}$ particles. Thus, only $ce{PbS}$ particles go into the froth. Now copper sulphate is added to the mixture which activates floating character of $ce{ZnS}$ and this time only $ce{ZnS}$ comes along with froth.
