Abstract. Cobalt (Co) is a potentially critical mineral. Most of its extraction is associated with a by-product of other mineral species such as copper, nickel and manganese, where it is a fundamental piece for activities that have increased their development in recent times such as electromobility, industrial and military applications.

Nickel ore dispersion before flotation using different reagents was investigated on a bench scale to improve metallurgical recovery and selectivity. The nickel ore had a content of 0.8 pct nickel and 14.5 pct MgO. A positive linear correlation between MgO and Ni was found. Carboxy methyl cellulose, both pure and combined with …
In this study, the robust Taguchi experimental design method was used to determine the optimum conditions for the flotation of nickel, copper and cobalt from a nickel-copper sulphide ore. The parameters investigated include collector dosage, percentage solids, depressant dosage and pH. The effects of these parameters at three different levels ...
6. In the extraction of nickel, roasted pentlandite [(NiFe) 4 S 8 ] concentrate is subjected to converting operation. The resulting matte is very slowly cooled from 1100 to 40 0 ∘ C (in 3 days), ground and magnetically separated to obtain a Cu − Ni alloy. Ni 3 S 2 and Cu 2 S are separated by froth flotation. The electrowinning of nickel is carried out with insoluble …

The solvent for nickel was prepared from commercial grade reagents obtained from R. T. Vanderbilt Company, Inc., and King Organic Chemicals, Inc. The DNSA samples as received were 36 percent and 41 percent DNSA in heptane. Twenty volume-percent of heptane solution in practical grade butyl ether was used to extract nickel. …
Escaid™ diluents are used in metal extraction. They provide higher flash point, lower vapor pressure and much lower aromatic content to the mining industry compared to traditional kerosene extraction diluents. Main metals extracted include copper, nickel and uranium. Escaid diluents are available in Escaid™ 110, Escaid™ 115 and Escaid™ 120.
Flotation is used to remove various metal ions. The general schematic of the flotation process is shown in Fig. 6 . Dissolved air flotation, ion flotation, and precipitation flotation were ...
It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., …
