Spodumene ores are typically consolidated from ore comprising 1–1.5% Li20 to a concentrate of about 6–6.5% Li20. To achieve this, the ore passes through a typical concentrator-type plant, flowing from crushing and grinding, to gravity separation and DMS, to flotation, and then to the final dewatering of the concentrate.

The flotation process is an ore concentration step, which requires using about 50–85% of water in the feed pulp. With that, in flotation alone, water consumption reaches an average of 0.96 m 3 per ton [5], [6], [7]. However, despite great criticism, the flotation stage is how fine-grained ores (between 10 µm and 150 µm in hematite/quartz ...

Flotation Process of Copper Sulfur Ore 1. Priority flotation. Generally, the copper is first, and then the sulfur is floated. The pyrite content in the ore is relatively high for massive copper-containing pyrite. High alkalinity (free CaO content >600~800g/m3) and high xanthate dosage are often used to suppress the pyrite by floating copper.
