Sherritt licenses its ammonia pressure leach process for nickel concentrates and mattes to Western Mining Corp. in Australia, and its acid pressure leaching process for PGMbearing nickelcopper mattes to Impala Platinum in South Africa. Sherritt starts pilot testing its laterite leach process for the Marinduque project.

Outotec, in fact, said it has constantly been developing new, sustainable, and economically viable nickel processing methods—and its nickel matte chloride leaching process is designed to leach matte in atmospheric OKTOP reactors using hydrochloric acid and oxygen, as well as ammonia for pH control. This innovative approach, according to the company, produces good overall metal recovery ...

This invention provides a process for treating a nickel matte to recover essentially pure nickel comprising: treating an aqueous mixture of the matte with chlorine to produce a solid residue and an aqueous lixiviating solution having a pH value which is substantially nil or positive; treating the lixiviating solution to produce a solution containing primarily nickel chloride; and electrolyzing ...
The Outotec Nickel Matte Chloride Leaching Process provides a reliable and environmentally sustainable processing method for various nickelcontaining raw materials. Our process utilizes highly effective Outotec atmospheric chloride leaching coupled with our worldrenowned VSF solvent extraction and electrowinning technology.

Jan 01, 2019 · The Nikkelverk refinery was acquired by Falconbridge Ltd. in 1929, and since then matte from Sudbury, Canada has been the main feed source. The Hybinette process was in operation until 1975 when conversion to the newly developed Chlorine Leach Process was started (Stensholt, Zachariasen, Lund, 1986).
In a first stage atmospheric leach in a typical Sherritt Ni–Cu matte leach process, a Ni–Cu–Fe–S Peirce Smith converter matte is contacted with recycled copper spent electrolyte (an aqueous copper sulphate/sulphuric acid solution) at 85 °C with the purpose of dissolving nickel, while simultaneously removing copper from solution. In the PGM industry, copper removal is also important ...
