Increasing the efficiency of copper concentrates production, smelting and electrolysis is possible by carefully selecting the optimal valves for each process. The most common copper ore types, copper oxide and copper sulfide, undergo two different refining processes – hydrometallurgical and pyrometallurgical, respectively.
The proposed hydrometallurgical process consists of two leaching stages for extraction of copper with H2SO4 – O2 and silver with thiourea – Fe3+. Pyrometallurgical treatment of the leaching solid residue for production of PbSn soldering alloy was proposed.

Copper Process Flowsheet Example. ... What of Ni/Cu processing facilities? Similar techno/economic to considerations make typical nickel producers unsuitable Only mixed nickel/copper sulphide capacity is suitable •Ni laterite unsuitable due to copper contamination in the PGM concentrate •Norilsk and Jinchuan have declined our feed in the past.
The pyrometallurgical process, used in Sudbury and around the world, is more commonly used for copper extraction than hydrometallurgical methods. This is mainly due to the fact that CuFeS minerals are not easily dissolved by aqueous solutions. The pyrometallurgical
A TECHNOECONOMIC COMPARISON OF PYROMETALLURGICAL AND HYDROMETALLURGICAL OPTIONS FOR TREATING HIGHARSENIC COPPER CONCENTRATES . N Haque. 1, *, W Bruckard. 2. and J Cuevas. 3. ABSTRACT . As the highgrade copper deposits in the world become depleted, there is an increasing focus on developing lowergrade ores which contain problematic impurities such as .
and alloys, with a previous roasting process. The objective of this research was, on one hand, to study gold extraction from an alluvial material, through a pyrometallurgical process, using chlorine gas as a reactant, and, on the other hand, to characterize the initial material and chlorination residues, using
oxide providing heat for the process as in copper matte converting. Again, an acid silica slag is used for the same reasons as in copper converting. The three products Ni3 S2, Cu., Ni—Cu alloy are subsequently cooled slowly through the range 925 0 c to 370 C, which allows first Cu2 S, then the Ni—Cu .
Simplified flowchart of the pyrometallurgical Incoprocess [5]. The aim of this study was to investigate the smel ting reduction operation from the Incoprocess. Inco proposed a smelting reduction operation without the addition of fluxes [5].
