CN100500299C - Phosphate rock floating process -

The phosphate rock floating process is one phosphate rock grading forward-backward floating process, in which the raw ore pulp is first separated into two parts of different fineness and then forward-backward floated in two separated branches. The coarse ore pulp is made to separated in high concentration so as to save floating chemical; while the fine ore pulp is floated through

1. Introduction. Flotation, which currently acts as a major purification process in various fields including but not limited to mining industry , and water/wastewater treatment , as well as recycling , , is a technique for separation of materials with different hydrophobicity based on their attachment to a low-density non-aqueous phase which is then separated from water by gravity.

This process is repeated to concentrate the gold bearing ore and separate it from the waste rock (increasing the grade of the ore). The flotation units catch 70% of the gold collected at Macraes, with the primary roughers collecting the other 30%. The slurry that doesn’t contain any gold is neutralised and sent to the tailings dam.
