Separation and recovery of iron and nickel from low-grade ...

01/11/2020  The magnetic separation efficiency of nickel from the laterite ore was evaluated using the recovery ratio of nickel R ni using the formula: (1) R Ni = m Ni × β Ni M Ni × γ Ni × 100 % where m Ni is the mass of the magnetic product, g; β Ni is the nickel content in the magnetic product, wt.%; M Ni is the mass of the reduction product, g; and γ Ni is the nickel content in the reduced laterite ore, wt.%.

Separation and Recovery of Nickel from Spent Electroless ...

For nickel recovery by electrowinning, the pH of the nickel solution required an adjustment of nearly 2.0. A method of recovering nickel from spent electroless nickel-plating solutions has been investigated through the electrowinning method, following the precipitation of nickel by adding alkali and then dissolving this nickel precipitate with sulfuric acid. When sufficient caustic soda was ...

Enhanced methods for nickel recovery from low-grade ores ...

The recovery of nickel from low-grade ores is increasingly more important, from new techniques of pressure oxidation of the concentrate in an autoclave to bioleaching of the nickel in the ore, it is evident that time and money are being put into researching these processes. Solvent extraction and ion exchange are also used in the recovery of nickel from various bleed streams from the electrorefining

The highest Ni recovery was 93%, as nickel phosphate, with a purity ≥96% in the sequence involving second EDTA precipitation, where 70% of the remaining EDTA was recovered at pH 0.4, followed by addition of Fe3+ and precipitation as nickel phosphate. However, this option has the highest costs in terms of reagents consumption. By suppressing the second EDTA precipitation step, nickel ...

Hydrometallurgy Metal recovery - Nickel/Cobalt

Purifying the nickel and nickel-cobalt separation can be done by ion exchange with IDA and chelating resins. These resins have a different affinity for the nickel and cobalt and other base metals. When separating nickel from cobalt, the nickel ion is more strongly retained by the resin. This difference of affinity can be exploited during the elution step of the process by using a split elution. The nickel,

Copper is a harmful impurity in nickel smelting, and the copper grade in copper-nickel ore has industrial recovery value. Therefore, copper-nickel separation technology is an important topic in copper-nickel ore beneficiation. Copper-nickel separation technology is divided into two types: copper-nickel mixed concentrate separation and high matte separation technology. Generally, the former is ...
