It is done in many types of furnace on both roasted or unroasted sulfide feed material. The reverberatory furnace is essentially a rectangular refractory ...Nickel and Cobalt Production | Request PDFThere is great potential to recover nickel from below cut-off grade nickel saprolite ores using the ... Recent process development work for the recovery of copper, nickel, cobalt and precious ...Metal Equivalent Calculation - How to Calculate the .You will often find the mineral chosen for reporting on a metal equivalent basis (i.e. the primary mineral) is the one that contributes most to the value of the deposit. Cautionary Note: Always make sure to read which prices were used when the metal equivalent calculations were made, due to potential differences between the prices used for the calculations and the current metal prices, which ...OUTOTEC SMELTING SOLUTIONS FOR THE PGM INDUSTRYAs in any extraction process, recovery of the metals is crucial. Fortunately there is little tendency for the PGMs to form species that can dissolve in the slag phases present during the various stages of the matte smelting of nickel. The PGMs therefore followAbout Equivalent Grade | MarketCap1.0% copper, 2.0% zinc, 0.9g/t gold, 20g/t silver. If we assume current USD metal prices are: Copper $8,400 per tonne ($84 per 1% of grade) Zinc $2,000 per tonne ($20 per 1% of grade) Gold $1,657 per ounce ($53 per gram ofTHE PRIMARY PRODUCTION OF PLATINUM GROUP METALS (PGMs)furnace at temperatures over 1,500 C.

Activities of CoS and FeS in copper mattes and the .

It was found that cobalt exhibits, in the matte-slag equilibria, chemical properties intermediate between nickel and iron, but much closer to iron than to nickel. The overall recovery of cobalt in blister copper depends on matte grade, and is as low as 3 pct at best.Leaching of a low-grade, copper–nickel sulfide ore: 2. .The conditions under which copper was retained and re-distributed in a test heap of pyrrhotite-rich, copper-nickel sulfide ore were investigated in abiotic column leaching tests.
