    Lead extraction was not followed further because of the research by Haver (11), who showed lead extraction from a galena concentrate to be 96 to 99 pct in 1 to 2 h at 50 C. Longer times and higher temperatures re sulted in further dissolution of other elements, but did not significantly in crease lead extraction. •

    Galena is the major lead sulfide. Galena in different place has differences in the types and amount of impurities and occurrence state. At the same time the floatability has large differences because of the lack of lattice. For example if there are silver bismuth and copper in galena its floatability is improved.
