Magnetic and gravity separation combined dressing experiment research on a iron-cobalt-gold ore abroad

A iron-cobalt-gold mine abroad contains magnetite,natural gold and cobalt minerals,according to the ore properties,comprehensive compared magnetic and gravity separation combined & magnetic and flotation separation combined,at last,flotation and gravity separation combined process to deal with the raw ore which the grade of Fe,Co and Au are 49.89%,0.047% and 0.82g/t.As result,we obtain iron concentrate with yield is 69.98%,Fe grade is 67.63%,recovery is 93.81%.Gold cobalt concentrate with yield is 0.25%,Co and Au grade are 10.22% and 197.57g/t,recovery are 56.51% and 57.21%.
