of pyrite concentrate
Approximately 279 million metric tons (mmt) of pyrite concentrate at 46 pct s is potentially recoverable from 422 mmt of in situ metal sulfide ore. Nearly 89 pct of the total pyrite concentrate is available at an average total cost of production below the January 1984 pyrite concentrate market price (43/mt).
Mina Justa Copper Project, Marcona, Peru
The Mina Justa copper project is designed to process 12Mtpa of oxide ore and 6Mtpa of sulphide ore. The Mina Justa copper mine is expected to produce 102,000t of copper concentrates and 58,000t of copper hode a year. Image courtesy of The EITI. The president of Peru launched the construction of the Mina Justa copper project in September 2018.

The effect of a novel depressant on the separation of talc ...
naturally hydrophobic, in copper sulphide processing, talc is easily reported to flotation concentrates, thus reducing concentrate grade and causing downstream processing problems as well as increased smelting costs (Beattie et al., 2006b; Feng et al., 2012a; Zhao et al., 2015). Sequentially, the separation of talc and other magnesiabearing ...
In the bessemerisation of sulphide ore of copper there ...
In the bessemerisation of sulphide ore of copper, the process involves the following steps: 1. The sulphide ore of copper is heated in the air until a part is converted to oxide. 2. Then further heating is done in the absence of air to let the oxide react with unchanged sulphide. 3.

In this process the ore is mixed with carbon and heated in a suitable furnace. 2. Electrolytic reduction process: This process is used in the extraction of the alkali and alkaline earth metals like zinc and Aluminium. 3. Selfreduction process: The sulphide ores of less electropositive metals like lead, copper etc. are heated in air so as to ...
