Nov 07, 2019· Copper Solvent Extraction. The separation of copper from nickel is based on the fact that there is an appreciable difference in the pH at which the two metals are extracted. Copper can be extracted, with very small amounts of nickel, at pH 6.0 to 6.5, while nickel is extracted from the copper raffinate at pH 8.0 to 8.2.

The serpentine content of the magnetically attracted fraction is reduced to about 30 percent by the magnetic separation and the nickel percentage is raised to about 3.5 percent. This material containing 3.5 percent by weight of nickel is ball-milled while dry for about 72 hours and subsequently wet-screened through a 325-mesh screen.

Sep 01, 2019· An interesting aspect of the magnetic separation of ore S (and partially ore I) is the enrichment of Mn in the magnetic concentrate. The amount of Mn was increased about 4 times from 0.4% and 0.2% in ores S and I, respectively, to 1.6% and 0.8% in the magnetic concentrates. The amount of Mn in the corresponding tails is more or less zero.
