A direct solvent extraction (DSX) process for purifying nickel and cobalt from the nitric acid leach solution of nickel laterite ores was conceived and experimentally probed. The proposed process consists of two solvent extraction (SX) steps but with only one extractant — bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex® 272) — used in …
Nickel laterites form where ultramafic rocks are exposed to tropical weather. Relatively high temperatures and rainfall cause the destruction of nickel-bearing minerals, olivine and serpentine and the leaching of silicon and magnesium. As a result, iron and nickel accumulate along with other less mobile elements and an iron oxide deposit is …

The effects of diluent composition, synergist, carrier and stripping agent …
Carbonylation refining technology has been used to extract nickel from nickel alloy. Before carbonylation, roasting and size reduction is used as a pre-treatment method, and re-activation with H 2 is needed. During carbonylation, the addition of H 2 S helps to activate the nickel surface and improve the extraction rate. The supply of H 2 …
The extraction of copper, nickel, cobalt and manganese were 77, 99.8, 88 and 99.8% respectively under the following leaching conditions: time 4 h, temperature 423 K, H2SO4 0.66 g of nodule and ...
It was found that the nickel extraction enhanced with the increase in sulphuric concentration, temperature and leaching time. The decrease in the particle size and solid to liquid ratio increased nickel dissolution. The extraction rate increased with increasing stirring speed and it was the highest at 500 rpm.
AbstractA cloud point extraction procedure was presented for the preconcentration of copper, nickel, zinc and iron ions in various samples. After complexation by 2‐(6‐(1H‐benzo[d]imidazol ...
The MPSAs of Hallmark and Austral-Asia hold control of the Pujada Nickel Project. In total, the Pujada nickel project covers 16,000 hectares of prospective mineral lands in Davao Oriental.
The authors have proposed a virtually SO 2 -free and one-step nickel extraction method, by which Ni values in the sulfide concentrate can be extracted into a ferronickel (FeNi) alloy with sulfur remaining in the solid as iron sulfide. Therefore, the evolution of SO 2 gas is significantly eliminated [ 5, 6 ]. In this paper, the authors studied ...
