The pyrite used as a sulfidizing agent was obtained from a mine in Anhui Province, China. The contents of Fe and S in the pyrite were 48% and 52%, respectively. The chemicals used in the flotation experiment, sodium hexametaphosphate and copper sulfate, were analytical-grade reagents supplied by Sinopharm Chemical Reagent (China).

Regarding pyrite from coal mining tailings, its beneficiation generates high calorific value waste that can be studied for power generation. Further, effluents, which has high iron content [10] can potentially act as a source of ferrous compounds. Therefore, this study aims to show for the first time the possibility of benefiting pyrite from ...

1.3 Run-Of-Mine Material and Minerals. Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility. At this point, the ore is called run-of-mine material because there has been no treatment performed on it. There are three primary types of run-of-mine materials: Run-of-mine consisting of useful materials.
