Direct extraction of copper from copper sulfide

Copper is predominantly recovered from sulfide ores by pyrometallurgy – an energy intensive process requiring capture and treatment of released SO 2. Whilst some copper ores are amenable to hydrometallurgy, chalcopyrite, the main copper mineral, is challenging to process in aqueous solutions due to surface passivation.

EXTRACTION OF COPPER - City Collegiate

2012-7-24  On industrial scale copper is extracted from its sulphide ore known as copper pyrite (CuFeS 2) by smelting method. Finely divided CuFeS 2 is concentrated by "Froth-floatation method". Crushed ore is suspended in water containing pine oil. A blast of air is passed through the suspension. The particles of ore get wetted by oil and floats as a ...

Mineralogical Characterization and Gravity Separation

2018-11-22  An in-depth mineralogical characterization has been carried out to develop a suitable beneficiation process route for a low-grade copper ore. Characterization and preliminary gravity separation studies were undertaken on low-grade Malanjkhand mixed copper ore to remove siliceous gangue and improve the copper grade. The characterization results indicated that the mixed copper ore

From long-lived batholith construction to giant

2021-1-28  Porphyry Cu ore deposits are a rare product of arc magmatism that often form spatiotemporal clusters in magmatic arcs. The petrogenetic evolution of igneous rocks that cover the temporal window prior to and during porphyry Cu deposit formation may provide critical insights into magmatic processes that are key in generating these systems. This study documents the magmatic
