Nickel and copper values are separately recovered from coppernickelsulphide matte by means of a multistage acid leach process. The matte is treated in a first leaching stage in which the acid to acidreactive metals molar ratio and leaching time are controlled to selectively extract the bulk of the nickel values while the copper values remain in the leach residue.
Processing'; and it is intended that the scope of exhibits should cover openpit methods as well as deep mining, exploitation of stratified minerals as well as orebodies, and all stages of the process from initial exploration and loion of the 'green field' to preparation of the product for the market.

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 ...
The Kell Process is a leap forward in PGM, polymetallic, gold, lithium and base metal concentrate processing technology, by bringing enhanced economic outcomes including much lower power consumption, efficient processing to metals in a matter of days and a range of environmental benefits.

which is passed directly to the wet process refinery of Johnson Matthey, and a converter matte that has been worked up from flotation concentrate. This matte is cast and either prepared for shipment to the Johnson Matthey smelter at Brimsdown in the United Kingdom or sent to Matte Smelters (Pty.) Limited, a company formed in South Africa in 1952 as a joint subsidiary of Rustenburg Platinum ...
process route employs a preleach step, which is essentially a matte repulping step, prior to a pressure leach step. The repulping process may be considered to be basically a non–oxidative atmospheric leach stage since leaching of the matte starts immediately it comes into contact with the CuSO4–H2SO4 repulping solution. During the preleach stage nickel, iron and cobalt are partially ...
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 ...
The process of patent 3,652,265 (Marschik et al.) utilizes an oxidative acidic pressure leach by treating ground matte and sulphur together with oxygen injection in an autoclave. This process, however, produces sulphuric acid and the nickel is dissolved in the form of sulphates, together with substantial amounts of highly soluble copper sulphates. Another process is described in ...

The processing facilities operated by the Sudbury Smelter include a smelter and a sulphuric acid plant. The Sudbury Smelter smelts nickelcopper concentrate from the Sudbury and Raglan mines and processes custom feed materials. It is capable of producing 130,000 tonnes of nickelcopper matte annually. The smelter's electric furnace converts the mineral concentrate into a highgrade matte ...
during the oxidising leach process in sulphuric acid media. In addition slag inclusions in matte leads to contamination of the PGM residues with silica, fayalite, magnetite and trevorite phases. Furthermore some Cu, Ni, Fe and S also remain. For this reason a typical Precious Metal Refinery (PMR) feed material contains less than 65% PGMs. The PMR is based on a chloride process and requires ...
· Norway Refinery: The search for a new more efficient and economic refining process was started at Falconbridge with many alternatives investigated initially. This led to the development of the Matte Leach Process employing hydrochloric acid to leach the matte selectively solubilizing the nickel. The acid nickel chloride solution, after solvent extraction to remove iron and cobalt, was ...
