Grinding

The grinding size is too large, and some ore particles and non-ore particles cannot be separated, thus preventing their flotation. If the particle size is too fine, the bubbles that rise during the flotation will push the very fine ore-containing particles away, preventing them from contacting the bubbles, thereby reducing their ability to be recovered into the concentrate.

Copper Sulphide Ore Flotation Process

Coarse-grained copper sulfide ore can use a stage grinding – a stage floatation process, and the fine-grained copper sulfide ore can adopt two stage grinding- two stage flotation process. What’s more, middling regrinding technology can reduce grinding energy consumption, which is widely used in ore dressing production.

Mechanochemical sulfidization of a mixed oxide-sulphide …

 · Mechanochemical sulfidization by co-grinding with sulfur was developed for treatment of a sulphide-oxide copper ore. • A 0.5 wt.% sulfur led to the higher floatability of copper owing to the formation of Cu—S bonding on copper oxides surfaces. • Adding Mg(NO 3) 2 and Fe(NO 3) 3 salts and iron, aluminum and magnesium powders were examined to improve the sulfidization.
