Separation of iron, nickel, and cobalt from sulphated

A two-stage selective precipitation technique was developed for the separation of iron, nickel, and cobalt from sulphated leach liquor of nickeliferous lateritic oxide ore obtained from Sukinda Valley, Orissa, India. In the first stage of precipitation, solid CaCO3 is added to the sulphated solution at 90 to 95degreesC till the pH is adjusted in the range of 2.2 to 2.5.

In this study, oxidizing roasting, segregation roasting, and magnetic separation are used to extract cobalt and iron from refractory Co-bearing sulfur concentrate. The Co-bearing sulfur concentrate containing 0.68% Co, 33.26% Fe, and 36.58% S was obtained from V-Ti magnetite in the Panxi area of China by flotation. Cobalt pyrite and linneite were the Co-bearing minerals, and the gangue

The aim of this study is to recover copper, cobalt and iron from roasted copper ore which contains copper, cobalt and iron in soluble forms. The solution was evaporated and enriched by copper and

Extraction of Nickel, Cobalt and Iron from

The low iron (< 15 % Fe) ores containing 1.7 — 2.3% Ni are treated by pyrometallurgical processes to produce ferronickel or matte. High iron (> 35 % Fe) limonitic ores can be treated by high pressure leach using sulfuric acid. An alternative process for the production of base metals (Ni, Co and Fe) from both high and low iron

Dissolution of Nickel and Cobalt from Iron-Rich Laterite

Due to the decreasing production of nickel and cobalt from sulfide sources, the Ni and Co extraction from the oxide ores (laterites) have become more prevalent. In this research work, the effects of calcination prior to leaching, acid concentration, percent solid, pH, and stirring speed on the nickel and cobalt recoveries from an iron-rich laterite ore sample were investigated using different

2012-2-7 The most striking feature of this separation process is the variation of cobalt recovery according to the iron content in the alloy. This behaviour is shown in Figure 4. It can be seen that the recovery of cobalt (in percentage terms) is highest (albeit not by very much) in the case of the slag with the highest initial cobalt content.
