Green And Efficient Comprehensive Utilization Of Pyrite

1. Introduction. Pyrite concentrates, which contain rich pyrite (FeS 2), are solid wastes or byproducts in nonferrous metal production processes, such as copper, lead, zinc, and coal treatment.Pyrite has been the mineral resource for sulfuric acid production in China, , , .However, the pyrite concentrate produced by polymetallic sulfide mines has a high content of impurity elements, and the ...

Oxidation Mechanism Of Pyrite Concentrates Pcs Under

Jul 01, 2020 Jul 01, 2020 1. Introduction. Pyrite concentrates (PCs), which contain rich pyrite (FeS 2), are solid wastes or byproducts in nonferrous metal production processes, such as copper, lead and zinc, and coal treatment.The best way to utilize PCs is using roasting process for sulfuric acid production and the solid roasting products can be used as raw materials for iron making .

Pdf Processing Of The Pyrite Concentrates To Generate

The results of two-stage roasting of pyrite concentrate with air blowing and the principle scheme of the process are presented in the report. The results of experimental sulfuric acid production tests using pyrite concentrate to generate sulfurous rich gas containing 0.1 0.15% of sulphur trioxide are shown. Comparative characteristics with technologies known for the present are given.
