free nickel containing hydrochloric acid solution is subjected to high temperature pyro - h ydrolysis in order to obtain a high purity nickel oxide product.
Extraction and separation of nickel and cobalt from saprolite laterite ore were studied by using a method of microwave-assisted hydrothermal leaching and chemical deposition. The effects of leaching temperature and time on the extraction efficiencies of Ni2+ and Co2+ were investigated in detail under microwave conditions. It is shown that the extraction efficiencies of Ni2+ and Co2+ from the ...

Pre-concentration of nickel in laterite ores using. This should have helped upgrading nickel in this ore using gravity separation. The level of upgrading (about 36%) may not seem large, but it is very important economically since 1.5% is the threshold for processing the nickel laterite ores in the mine where the sample was obtained.

Sulphuric acid, hydrochloric acid, and nitric acid are the three major mineral acids for the leaching of laterites. The comparative analysis has shown that both the chloride and the nitrate circuits examined have appreciably lower operating costs than the sulphate circuits. The dissolution kinetics of nickel lateritic ore in an aqueous acid ...

Hydrometallurgical process of laterite nickel ore is carried out by leaching techniques at high temperatures. At atmospheric temperatures, the acquisition of nickel is low. Therefore, this study aims to characterize the electrochemical laterite nickel ore using a solution of sulfuric acid and hydrochloric acid at atmospheric temperature.
Nickel laterite leaching is usually performed by capital-intensive pressure sulfuric acid leaching(4, 5) although hydrochloric acid is more effective(6). As hydrochloric acid can be recycled, operating costs of hydrochloric acid based flow sheets are estimated to be lower as for sulfuric acid flow sheets(7).

The invention discloses a laterite-nickel ore clean production method. The method comprises the following steps: brown iron type laterite-nickel ore hydrochloric acid normal-pressure leaching, selective leaching of serpentine type laterite-nickel ore in the above obtained acid leachate, a hydrolysis coupling reaction, and separation and purification of oxides containing Fe and Si to prepare ...
in the mineral ore making it difficult for separation and purification processes, such as nickel which is not present in nature but mixed in laterite nickel ore. Low-grade laterite contains nickel around 0.4% as listed in Table 1. This laterite is very difficult to process but this low-grade laterite …
