Coal Flotation Cost

  • Coal Flotation Technical Review Acarp

    Reagent consumption, according to conventional wisdom, accounts for 50-60 of flotation operating costs. Column flotation is expected to require more reagents on account of the much larger bubble surface available. This was found to be true, with frother consumption about double the rates used in conventional flotation.
