Detail1990-1-1It was found that barium sulphide yellow ammonium sulphide in the case of metal is preferable to hydrogen sulphide for this purpose. The quantity of sulphide to be added was determined by the quantity of nickel, copper, cobalt salts, etc., in the electrolyte. The washed and dried flakes of EMD are crushed in a roll crusher and then ground.
DetailThe wire shape is the least floatable, while the flakes respond well to xanthate flotation at a pH of 911. A pH 9 has a negative effect on the floatability of native copper. The use of Na2S has a positive effect on native copper flotation and it is known that additions of 100500 gt improved native copper significantly.
