After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel concentration greater than 99%.
2013-12-1 · The world’s resources of nickel are found as sulphides and laterites and while almost ¾ of the world’s resources of nickel are found as laterites, currently less than half of the primary nickel production comes from laterite sources as illustrated below (Dalvi et al., 2004).This is illustrated in Fig. 1.1.. Download : Download full-size image Fig. 1.1.
The processing of nickel laterites has been a topic of major interest at CSIRO for almost twenty years. During this period CSIRO has collaborated with other researchers and

The most commonly-used material for high-quality bathroom andkitchen fittings is brass that is plated with nickel, usually with a thinktop layer of chromium. The photos above show nickel-chromium-plated shower parts.
1. A method for nickel concentration processing of a saprolite ore, characterized by comprising the steps of the following (1) to (4). (1) a saprolite ore is subjected to crushing processing to adjust the ore particle size to a size passing a sieve with an mesh opening of 50 mm. (2) a crushed ore obtained in the step of the above (1) is subjected to dry-type grinding processing of the surface ...
Direct Nickel has developed a game changing pro cess for extracting nickel from laterite deposits. It will position Direct Nickel as one of the lowest cash cost producers in the global nickel industry in the next 5 years. The Process offers unparalleled co st efficiency, capital savi ngs and environmental benefits.
2019-3-20 · Extraction of Nickel. This paper introduces the extraction of nickel process and characteristics of laterite nickel ore dressing, highlights the nickel ore crushing, washing in the nickel production process design.. 1 Description of nickel ore. The laterite nickel ore is complex in composition and can be roughly divided into two types: limonite type and silicon magnesium-nickel type.
Physical processing methods are also not efficient, because of the fine microstructural intergrowth of the minerals carrying valuable elements such as nickel and cobalt. Due to the high energy ...
A proof-of-concept for the carbonation-assisted processing of ultramafic nickel ores is presented. Carbonation converts serpentine, the primary gangue or undesirable mineral, to magnesite. It prevents slime coating of fine gangue minerals on pentlandite, the
2020-4-5 · First of all, it is a key to decrease the cation-ion mixing during the synthesis process of nickel-rich cathode materials. Besides the proper sintering temperature and Li/M ratio, element doping is also a well method to decrease cation-ion mixing and stabilize the layered structure.
