Copper matte converting is an essential process in copper pyrometallurgy. Replacing traditional batch Peirce–Smith converters (PSCs), continuous becoming a new trend. In this work, thermodynamic modeling of the was carried out under actual production conditions. There were five phases process: matte, copper, Cu2O, slag, and gas. To directly produce anode divided into oxidation period reduction ...

A previously developed unified model of a tungsten-inert gas (TIG) microarc has been extended to take into account the melting anode made copper and release atoms due its evaporation. The enter plasma become excited ionized. presence ions can strongly change parameters. further includes states collisional radiative processes between them. Predictions parameters in species are presented discussed.

Despite the enormous efforts devoted to high-performance lithium-ion batteries (LIBs), the present state-of-the-art LIBs cannot meet the ever-increasing demands. With high theoretical capacity, fast ionic conductivity, and suitable charge/discharge plateaus, Li3VO4 shows great potential as the anode material for LIBs. However, it suffers from poor electronic conductivity. In this work, we prese...

master moulds are used to cast copper anode moulds. these iron moulds are made of grey or nodular cast irons. according to desirable properties of ductile irons, it was expected that ductile cast iron moulds could have performed their nominal life. but in service, these moulds have not performed their nominal life and they have experienced premature failures due to warping and cracking. also gr...

In recent years, the demand for copper and nickel has risen world-wide due to their use in printed circuit boards, batteries, application in marine alloys (due to excellent resistance to corrosion by seawater), and a wide range applications in day-to-day life (Doebrich, 2009). Increasing demand for these metals is leading to rapid depletion of high-grade resources. Alternative sources, such as ...
