For laterite ores, these are the main routes used in the hydrometallurgical nickel processes. One notable exception in recent times was the Bulong project, which succeeded in achieving A New Process for CoNi Separation – ALTA 2010 3

The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron (< 15 % Fe) ores containing — % Ni are treated by pyrometallurgical processes to produce ferronickel or matte.

A nickel laterite ore treatment process, characterized in that said treatment process comprises: the nickelcontaining laterite ore, iron oxide content of more than 50wt% seed mixed with sulfuric acid to obtain a slurry of the reaction; to be carried out and the reaction pressure leaching process slurry, and leaching residue obtained leaching .
Recovery from laterite ores. Nickelcobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes, such as matte or ferronickel smelting, which require the entire ore to be melted and the metal values to be separated from the residual components of the ore. The hydrometallurgical process for laterite ore can use sulfuric acid or ammonia leach solutions.
I am looking for any suggestions/input on methods to more completely digest a nickel laterite sample. Currently, my lab is using an aqua regia digestion using 5 g of pulverized sample (200 mesh) with 25 mL of aqua regia on a hotplate. We have been having difficulties in mass balancing the nickel am
Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. formed phyllosilie minerals. All the nickel in the silie zone is leached downwards (absolute nickel concentration) from the overlying goethite zone. ... nickel and cobalt ores: flotation Semantic Scholar. of the presentday nickel sulfide ores renders them ...
Nickel is found in two key types of deposits; Nickel laterites and magmatic (volcanic) sulphide deposits. Although nickel laterites contain around 70% of nickel reserves, most historical nickel production has come from nickel is changing as nickel sulphide reserves deplete and the worlds consumption of nickel grows steadily each year.
for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a whole is always maintained. In this study, the robust Taguchi experimental design method was used to determine the optimum conditions for the flotation of nickel, copper and cobalt from a nickelcopper sulphide ore. The parameters

May 11, 2015· Akira Otsuki of the Université de Lorraine, France presented work on a study aimed at investigating the sulphidisationflotation of nickel oxide, the major nickel form available in nickel laterite. Sulphidisation was conducted before flotation to convert the surface of nickel oxide to nickel sulphide.
Nickel laterite leaching Outotec is continuously testing and developing an optimum atmospheric leaching process for nickel laterites. In the process, different nickel laterites are leached in several cocurrent stages in atmospheric reactors, depending on ore mineralogy. A viable option for concen
Nickel pig iron (NPI) is usually made with lower grade limonite ores while ferronickel (typically 8 to 12% Ni) is made with higher grade nickel laterite ores, often saprolites (lower iron content) or in the case of limonites by lowering the iron recovery.

minedout massive ore body. The bulk of the disseminated sulphides contain nickel values of around % with massive sulphide lenses yielding nickel tenors in excess of 2%. Metallurgical test work was conducted by Mintek, on the drilled bulk samples, incorporating dense media separation and flotation. Recoveries of 72% were indicated.
