Limestone sample primarily constituted of calcite, dolomite, quartz and pyrite which was major gangue mineral phase in samples. Pyrite is highly dispersed in limestone.

Pyrite, a mineral with a chemical formula of FeS 2, is an iron disulfide, which is usually associated with other sulfides and oxides. It is abundant in the earth's surface, being found in the composition of sedimentary and metamorphic rocks, in coal beds and as a replacement mineral in fossils (Klein and Hurlbut, 1993 ).

Conclusion. The pyrite from coal mining in southern Santa Catarina (Brazil) is rich in other ferrous compounds, sulfates and oxides according to the infrared spectra. The high silicon content, together with elements such as aluminum, calcium, potassium, magnesium, manganese and sodium, suggest that the material has a sandy and clay …

The beneficiation of pyrite is mainly completed by gravity beneficiation methods and equipment. The gravity beneficiation of pyrite is based on the difference in specific gravity between pyrite and gangue. The specific gravity of pyrite is 4.9-5.2, and the specific gravity of gangue associated with pyrite is not more than 3.0.

Beneficiation of pyrite from coal mining - ScienceDirect. An abundant mineral in nature and despite its potential as raw material for different segments of industry, when it comes from coal mining, pyrite (FeS 2) is treated as waste, and its disposal culminates in environmental problems for the coalfields.

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 ...
