Iron Sulfides
The iron sulfide greigite (Fe 3 S 4) is the ferrimagnetic inverse thiospinel of iron and its crystalline structure is comparable to that of magnetite (Fe 3 O 4) in which sulfur replace oxygen atoms. In the cubic close‐packed crystal structure of greigite, the tetrahedral A‐sites are filled by Fe 3+ ions and the octahedral B‐sites are ...
Copper Processing Plant
Due to limited funding, a gravity separation process after the crushing stage is applied to recover copper sulfide ore, resulting in less minerals acquired. For improved recovery, we use our flotation machines to save on costs and ensure that enough ore is extracted after the grinding stage for copper sulphate manufacturing plants.
