Electro-flotation of chalcopyrite

Abstract

Electro-flotation tests were conducted on chalcopyrite particles with a modified Halhmond tube designed for electro-flotation, using platinum anode--copper cathode and graphite anode--copper cathode systems. Flotation tests were carned out for frees of chalcopyrlte of size below 20 microns with potassmm ethylxanthate as collector_ Studies were done on flotation with hydrogen and oxygen separately with the usual varmbles. Dissolution of chalcopyrite at various current densltms, with reagent at optimum conditions and without reagent was also studied. It is observed that electro-flotation partmularly with oxygen, is effective in the flotatmn of fine particles of chalcopyrite_
