    The iron content in the alloy was lowered from 76 to 25%, with the effect that the alloy was concentrated up to 30% cobalt and 40% copper. The sulphur level in the resulting alloy was %. This means that 75% of the cobalt remained in the alloy, while 90% of the iron was removed to the slag.

    In MCIX column tests, the iron extraction kinetics were slow relative to those of cobalt, nickel, copper, and zinc, and only 10 to 15 pct of the iron was extracted. Since iron was extracted at a slow but steady rate as the feed solution passed upward through the column, longer column lengths resulted in higher iron .

    Copper is also a metallic element; it has the atomic number 29. Copper is used as a conductor of heat and electricity, as a building material and in various metal alloys. Copper salts are some of the most important copper compounds, which give blue and green tints to materials such as turquoise and are frequently used decoratively or as pigments.

    The Outokumpu district in Sweden also produced cobalt as a primary product until operations ceased in 1994. However, a mine is currently under development at Kylylahti which contains around million tonnes of ore grading % copper, % cobalt, % nickel, % zinc and grams per tonne gold and could begin

    Separation of copper, cobalt and iron in solution obtained from copper ore. The remaining solution of electrolysis process was evaporated and a mixture of CoSO4, FeSO4 and H2SO4 was remained. In order to separate cobalt and iron ions from the mixture, 96 % of ethyl alcohol solution was used and pure cobalt was left in a solid form of CoSO4 center dot 7H (2)O.
