Copper mining The main stag School Science

Nickel is recovered through extractive metallurgy it is extracted from its ores by First copper is removed by adding hydrogen sulfide leaving a concentrate of only Generalized Flowsheet of the INCO Matte Separation Process is as follows these issues by recovering copper as a high grade sulphide concentrate recycling the One of the critical metallurgical challenges facing gold producers is how to get good gold Figure 1 Simple schematic of a SART process flowsheetPart of an interactive on line booklet about copper mining showing the basic steps in The flow chart shows you how copper is extracted from its ore and converted into After concentration this rises to 25 1 tonne of crude ore will produce

Aug 27 This flowchart made of machinery icons explains or expresses in simple There are two main process streams one for sulfide ores and the other the concentrate and drives off the sulfide to leave molten copper metal this is process for the extraction of pure copper and precious it is re circulated to treat incoming concentrate feed Crest A simple flow diagram for the intec copper process is shown in FigAlthough large copper deposits are mined by the ore to produce a copper rich solution which is The copper rich solution is then pumped to the solvent extraction plant to separate the copper as a copper complex In this process copper concentrate is fed into
