2020-1-15 The DNi process is being developedby Direct Nickel Limited, Australia, for the processing of both limonite and saprolite ores. It is an atmospheric nitric acid leaching process coupled with a patented acid regeneration system. Nickel and cobalt extractions are high (reported to be > 90%). No secondary neutralization is needed to remove residual
Unlocking millions of tonnes of nickel CSIRO
Traditional nickel laterite processing techniques use large quantities of sulphuric acid at high temperatures and pressures, resulting in expensive waste treatment and disposal of the chemicals used in the extraction process. Nickel laterites are becoming a priority for mining companies as traditional nickel
BHP Ravensthorpe Nickel Operation, Australia Mining
2021-10-8 Ravensthorpe was a laterite nickel project which, because of the ores’ low grade, and expensive and intensive processing requirements, has caused BHP some headaches. The project was originally approved in March 2004 with a budget of
Processing of Nickel Laterite Ores on the Rise
Lateritic Nickel Ore Processing. While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below. The method(s) chosen is dependent on the
Understanding Feed Rheology in Nickel Laterite Processing
In many cases, plants have been designed using rheological data obtained for limited or ‘representative’ samples. Due to a number of rheology related failures and process difficulties encountered by these projects, this is now understood to be a practice that results in excessive risk. Nickel laterite ores

Minerals Free Full-Text Nickel Laterites—Mineralogical
2021-10-24 Nickel laterite ore is used to produce nickel metal, predominantly to manufacture stainless steel as well as nickel sulfate, a key ingredient in the batteries that drive electric vehicles. Nickel laterite production is on the rise and surpassing conventional sulfide deposits. The efficiency of mining and processing nickel laterites is defined by their mineralogical composition.

Salinity in Nickel Laterite Processing SGS
The effect of salinity on the processing of various nickel laterite ores is discussed. In particular, the presence of . high concentration chloride, sulphate, sodium, calcium and magnesium is addressed. Key unit process operations affected by these ions include ore preparation, pressure acid leaching, counter-current decantation and product
