Acid sludge has been used with good success on Butte copper ores, but the disadvantages of this are that it requires heat and also additional quantities of acid to get the best results. This means working with an acid pulp and prevents the introduction of the oil into the crushing plant because of the destructive effect of the acid on anything ...
The graphite ore mining process is mainly suitable for all kinds of graphite with different crystal habits and graphite accompanied by mica, silicate minerals, or pyrite. The beneficiation process includes flotation, electrostatic separation, gravity separation, etc. And flotation is …
Secondly, the presence of pyrite in copper ores requires the use of lime in such a way as to avoid the flotation of this iron sulfide mineral. Previous studies show that calcium generates an effect that boosts the negative effect of clays in the flotation process of copper ores. This is an important difference compared to other applications.
