22.07.2022The flotation method is commonly used to separate copper. Combined type copper oxide ore. Combined copper oxide minerals are wrapped by limonite or mud in very fine granular form. If the gangue mineral is silicate, it is difficult to beneficiate. If it is carbonate, it is more difficult to beneficiate.

Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance. These are added separately or, as is becoming common, are supplied as blended products to optimize flotation. Frothers are an important flotation reagent suite consideration.

Traditionally, flotation separation of dark-coloured minerals and nepheline is carried out in an alkaline environment (pH~11), which is due to both natural pH of crushed ore suspension and pH = 9.8 of apatite flotation at the first stage of beneficiation. In the region of pH 9.5, there is a difference in the floatability of titanite and nepheline with pelargon hydroxamic acid (Fig. 1).

Most often the copper minerals are floated after galena depression. Galena is depressed using sodium dichromate, sodium sulfite, polysaccharide (starch, dextrin) or even CMC. Addition rates of these depressants can be critical if any recirculating load is returned to the bulk rougher circuit. This flotation step is conducted at alkaline pH.
