Nickel Sulfide Versus Laterite : The Hard Sustainability

laterite compared to sulfide ores leading to a historical preference for sulfide ores. To meet future demand for nickel, however, there is an increasing proportion of nickel being mined from laterite ores. This leads to an important issue in terms of the environmental costs of nickel as laterite nickel

Ni-Co LateritesA Deposit Model

There are generally five groups of silicate minerals in the hydrous Mg-silicate type Ni laterite ore, which include the poorly crystalline garnierite group, sepiolite group, serpentine group, talc group, and chlorite group (Brand and others, 1998; Freyssinet and others, 2005).

Laterite Ore Processing | A Blog for Browsing Mining

Aug 27, 2012· Some of the world class Nickel Laterite ore deposits have Cobalt, Copper and PGE values. Recovering all these metal values in a single refining step is a major challenge. Carbonyl Vapor Metallurgical process is a viable technology to over come this challenge, and also Feasibility Study shows better economics in refining laterite ore via Carbonyl

Home An Introduction in Laterite

Below the nickel limonite another type of nickel ore has formed in many deposits. This is called nickel silicate ore which consists predominantly of partially weathered serpentine. It is depleted in magnesium and forms with 1.5 2.5 % Ni the most relevant type of lateritic nickel ores.

LATERITIC DEPOSITS Subsite Template

Nickel-cobalt lateritic deposits are residual concentrations formed by tropical-style weathering of ultramafic rocks. Lateritic deposits include a number of deposit sub-types that result from

The nickel laterite challenge Australian Mining

Jun 21, 2012· Nickel occurs in essentially two ore types; magmatic sulphides and ('wet' or 'dry') laterites. The sulphides typically are found hundreds of metres below ground with principle mineralisation

Ni-Co Laterite Deposits of the WorldDatabase and Grade

May 26, 2011· The United States has no active nickel mines or nickel reserves. Ni-Co laterite deposits provide one of two major natural sources of nickel and cobalt. The economic importance of this deposit type expands in direct relation with industrialization of developing countries. Until now, the world nickel supply has been predominantly from sulfide deposits.

Enhanced methods for nickel recovery from low-grade ores

Sep 06, 2017· Production of Nickel from Lateritic and Sulfide Ores In 2009, the world's top nickel producers were Russia, Indonesia, Canada, Australia, and New Caledonia. Nickel is produced primarily from laterite and magmatic sulfide deposits.

Nickel Laterite's Integral Role in the Coming Nickel Boom

Nickel laterite ore processing depends on the zone from which the ore is mined. As outlined earlier, each zone within a laterite deposit is very different in its chemical composition and, therefore, restricts the processing technique that can be used to extract the nickel.

Mar 06, 2019· Class 1 nickel (high purity) and Class 2 (lower purity) nickel and sulphide ore versus laterite ore Class 1 nickel is the high purity nickel that is used in electric vehicle lithium ion batteries.

Acid Pressure Leaching of Nickeliferous Laterite Ore

The AMAX sulfuric acid leaching process involves countercurrent digestion of nickeliferous laterite ore at high pressure and at atmospheric conditions. After solid/liquid separation, the nickel and cobalt values are precipitated by hydrogen-sulfide and refined into nickel and cobalt metal.

Extractive Metallurgy: Extraction of Lateritic Nickel Ore

Dec 23, 2008· This initial nickel content is strongly enriched in the course of lateritization. Two kinds of lateritic nickel ore have to be distinguished: limonite types and silicate type. 1. Saprolite : Low iron (Fe), contains generally 1.5-2.5% nickel and consists largely of Mgdepleted serpentine in which nickel

Laterite Ore an overview | ScienceDirect Topics

The laterite ore is dried and reduction roasted in multihearth roasters in an atmosphere containing hydrogen and carbon monoxide in the absence of air. Nickel and cobalt are selectively reduced to the metallic form and thus rendered amenable to ammoniacal leaching, while iron remains as insoluble oxides and silicates.
