Sherritt licenses its ammonia pressure leach process for nickel concentrates and mattes to Western Mining Corp (Australia), and its acid pressure leaching process for PGM-bearing nickel-copper mattes to Impala Platinum (South Africa). Sherritt starts pilot testing its laterite leach process for the Marinduque project (Philiippines).
Figure 2. Simplified block flow diagram of the Bulong flow sheet The most recent major nickel laterite project, namely Vale Inco's Goro nickel project, was commissioned during 2012. Nickel is also recovered via direct SX (no prior precipitation of nickel and cobalt) using Cyanex 301 [bis(2,4,4-trimethylpentyl) dithiophosphinic acid].
Various hydrometallurgical flow sheets are being used for the recovery of nickel from laterite ores. Most plants use the Caron or HPAL processes, for which simple block flow diagrams are given in Figure 1. The Caron process is considered primarily for limonitic ores to avoid the high acid consumption associated with the iron content in the ore. The
Nickel (Ni) is a transition element that exhibits a mixture of ferrous and nonferrous metal properties. It is both siderophile (i.e., associates with iron) and chalcophile (i.e., associates with sulfur). The bulk of the nickel mined comes from two types of ore deposits:

Mar 15, 2016· 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 Mackenzie reviews.
The nickel content of laterites varies widely: at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel; currently it contains 1 to 3 percent. Mining. With nickel found in two radically different types of ore, it is not surprising that the mining methods differ.
Processing nickel involves a variety of technologies, from concentrating techniques to pyrometallurgical and hydrometallurgical processing. There are different processing routes to choose from, too, adding another layer of complexity to the flow sheet selection mix.

May 07, 2018· Mining Solutions | ... Nickel laterite ores are becoming an increasingly important source of nickel and cobalt. BASF chemists and engineers have developed a flow sheet for the recovery of nickel and cobalt from laterite ores. It uses a high pressure acid leach followed by clarification and precipitation of a metal hydroxide cake which is then ...
This paper presents a life cycle assessment (LCA) study of three nickel laterite processing technologies. The main goal was to quantify selected environmental impact categories and to compare and analyse each impact category for three different nickel feedstock for stainless steel production.

Sep 06, 2017· The other type of nickeliferous laterite is known as nickel silicate, which contains less than 30% iron, 30% silicon dioxide, and about 1.6% nickel. In general, laterite has high concentrations of iron, titanium, and aluminum oxides. With these low percentages, not all nickel recovery from laterite mining is economically feasible.
The deposit is a large, flat, near-surface, continuous, nickel laterite deposit, with associated cobalt and local elevated platinum and scandium. A mineralised layer up to approximately 40 m thick covers an area about 4 km x 2 km and lies 0–30 m beneath the surface. It thins at the edges presenting a basin like form.
Nickel mining in New Caledonia is a major sector of the New Caledonian economy. The islands contain about 7,100,000 tonnes of nickel which is about 10% of the world's nickel reserves .With the annual production of about 107,000 tonnes in 2009, New Caledonia was the world's fifth largest producer after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000).
