INCO for the treatment of a nickel laterite deposit in New Caledonia. The flowsheet involves the coextraction of nickel and cobalt by SX with the extractant Cyanex 301, followed by their separation in a chloride medium by SX using an amine extractant. The lateritic ore is acid leached under pressure at 270°C. The clarified autoclave
Separation of manganese, zinc and nickel from ... hydrochloric acid solution up to 10 mol/L in which ... Ni laterite ore) bearing Co, Ni and high content of Mg was carried out by LEE et al [14] using D2EHPA, PC88A, Cyanex 272, Alamine 336 and their combinations. The extraction of Ni was negligible with
Recovery of Ni, Co, Mn, and Mg from nickel laterite ores using alkaline oxidation and hydrochloric acid leaching Article (PDF Available) in Separation and Purification Technology 143:8087 ...
• Strong nickel and cobalt extraction makes stripping difficult. The Goro process was designed to use hydrochloric acid stripping in four stripping stages, each with 5 minutes residence time in the mixer, at an operating temperature of 60°C and a residual hydrochloric acid concentration of 3M
determine the behaviour of lateritic nickel ore from the Eski ehirMihalJççJkKaraçam deposit in a hydrochloric acid leach under atmospheric conditions, and the leach experiments were repeated using mixed aquous medias for comparative purposes. In these experimental studies, hydrochloric acid (37%, d: g/cm3) and deionized water were ...
reliable and costeffective methods for the determination of metals in base metal ores. Accurate analysis is vital for determining the commercial ... acid (6870% m/v), hydrochloric acid (% m/v), phosphoric acid (min. 85% m/v) and sulfuric acid ... OREAS 189 Nickel laterite ore Fe, Mn, Ni Phosphoric acid OREAS 701 Highgrade tungstencop ...
The laterite ore sample used in this study came from Yunnan province of China; it belongs to a special kind of laterite nickel ore, which contains approximately % of magnesium and % of ...
A hydrochloric acid hydrometallurgical process was evaluated for Ni and Co extraction from a lowgrade saprolitic laterite. The main characteristics of the process were (i) the application of a countercurrent mode of operation as the main leaching step (CCL), and (ii) the treatment of pregnant leach solution (PLS) with a series of simple precipitation steps.
for the activation energies of laterite dissolution in hydrochloric, nitric and sulphuric acids respectively; and the order of reaction was approximately one with respect to each of the three acids. Keywords: Lateritic soil, Dissolution kinetics, Hydrochloric acid, Nitric acid, Sulphuric acid. 1. INTRODUCTION
Separation of nickel and iron from lateritic ore. This paper investigates extraction of nickel and iron from a lateritic nickel ore from the Caldag region of Manisa in Turkey. The ore sample contains % Ni,...
Interruptive pressure acid leaching experiments were also performed at 250°C on the samples from five different locations of the Ivory Coast ore body. Process conditions such as acid/ore ratio and pulp density were calculated from a spreadsheet provided by Falconbridge Limited.
The lateritic ore came from the Karaçam region, Eskişehir, Turkey. The raw material used in this work was a typical limonitic laterite ore with high iron content. It was ground to size less than 106 µm for acid leaching. The elemental composition of the sample is given in Table 1. Table 1 Elemental analysis of lateritic nickel ore sample [35]
and hydrochloric acid was 65% and mL/g, respectively, the nickel leaching rate of single sulphation roasting−water leaching is much higher than that of single hydrochloric acid leaching. That is to say, single hydrochloric acid leaching cannot obtain high nickel leaching rate.
Mar 16, 2012· Hydrochloric Acid is a highly corrosive chemical compound comprised of hydrogen chloride and water. Hydrochloric acid is also known as spirits of salt or muriatic acid. It is colorless and has wide ranging uses and applications. Hydrochloric acid is a natural part of gastric acid .
