Nickel processing

Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating …

Taganito HPAL Plant Project

The objective of Taganito HPAL Project is to produce 30,000 MT of nickel and 2600 MT of cobalt as sulfide with treatment of nickel laterite ore in the Philippines and to export to SMM Nickel Refinery in Japan as raw material for 30-years.In other words, 1.15 wt% of nickel content in ore is finally upgraded up to 99.99 wt% in electrolytic nickel.

A life cycle assessment of a new laterite processing technology

The nickel laterite processing routes were (1) high pressure acid leaching (HPAL), (2) ferronickel, and (3) the newly developed Direct Nickel (DNi Process) that involves atmospheric leaching of nickel laterite using nitric acid. A cradle to gate approach was adopted.A functional unit of one tonne stainless steel was chosen.

Ni-Co laterite deposits | U.S. Geological Survey

Nickel-cobalt (Ni-Co) laterite deposits are an important source of nickel (Ni). Currently, there is a decline in magmatic Ni-bearing sulfide lode deposit resources. New efforts to develop an alternative source of Ni, particularly with improved metallurgy processes, make the Ni-Co laterites an important exploration target in anticipation of the …

Why heap leach nickel laterites?

The world's resources of nickel are either sulphides or laterites and while almost ¾ of the world's resources of nickel are found as laterites, until 2009 less than half of the primary nickel production came from laterite sources as illustrated in Fig. 1.1 (Dalvi et al., 2004).This figure has been updated to 2009 production using data from Wood …

Nickel laterites are the future. Nickel can be produced from either sulphides or laterite ore. About 72% of the world's nickel resources are laterites found mainly in tropical locales such as Indonesia, Cuba, Brazil and New Caledonia. The remaining 28% are sulphides primarily located in Canada and Russia.
