Separation of copper and cobalt–nickel sulphide

Apr 01, 2005· Applying sulphide precipitation for separation of copper and nickel–cobalt concentrates from manganese sulphate solutions is advantageous because copper sulphide precipitation is operative in the acid pH range, cobalt and nickel precipitation in a weak acid pH range while Mn sulphide precipitation is successfully performed in the alkaline pH range (Monhemius, 1977). Due to the fact

separation of copper sulphide and nickel sulphide matte in

separation of copper sulphide and nickel sulphide matte in Matte, crude mixture of molten sulfides formed as an intermediate product of the smelting of sulfide ores of metals, especially copper, nickel, and of being smelted directly to metal, copper ores are usually smelted to matte, preferably containing 40–45 percent copper along with iron and sulfur, which is then treated by

Separation Of Copper Sulphide And Nickel Sulphide Matte In

Copper sulphate can be used to separate Copper from Nickel in a sulphide ore or Copper from Fe in Cu -Fe sulphide ore. CuSO 4 solution can also be used for removing Pb, Zn, and Fe from copper sulphide ores. In presence of oxidizing agents: Ferric ion: Ferric sulphate or chloride react with metal sulphides liberating elemental sulphur, e.g.

PRE-CONCENTRATION OF LOW GRADE LATERITIC SULPHIDE

mined-out massive ore body. The bulk of the disseminated sulphides contain nickel values of around 0.3% with massive sulphide lenses yielding nickel tenors in excess of 2%. Metallurgical test work was conducted by Mintek, on the drilled bulk samples, incorporating dense media separation and flotation. Recoveries of 72% were indicated.

metallurgically from the sulfide ores. The nickel sulfide ores account for approximately 30 % of the global nickel deposits, the rest of the nickel in Earth’s crust is contained in laterites an oxide ore. Nickel production from sulfide ores is reaching a plateau, and a gradual shift to the exploitation of laterites was a logical development.

A New Process for Cobalt Nickel Separation

excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching.
