Column Flotation • Theory and Practice

Separation of valuable minerals from gangue is far from ideal in conventional mechanical cells. Column flotation, invented in the early sixties, proved to be a better alternative to the conventional cells. The main advantages of column flotation are : i) improved recovery, ii) higher grade, iii) lower capital and operating costs, iv) less wear and tear due to absence of moving parts and v) requirement of less floor
