jul 01, 2021 after the roughing flotation, the recovered rougher copper concentrate was further upgraded in a three-stage cleaning circuit to obtain a high grade cu-s concentrate. for this, the rougher concentrate was transferred into a 1 l flotation cell where it was further diluted by the addition of tap water to achieve a density of 20 solids.,effect of desliming on flotation response of kansanshi,4. conclusions. the outcome of this work has shown that desliming improves the flotation response of the kansanshi mixed copper ore. at a rougher copper concentrate grade of 8, metal recoveries obtained with desliming were in excess of 70 compared
