Extraction. Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.
Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.
When mixed oxide-sulfide nickel ore is treated by the existing process for high-grade nickel sulfide ore, approximately half of the non-ferrous metals including nickel, copper and platinum group metals are lost (Kosyakov et al., 1995), resulting in low recovery of valuable metals and poor economic benefit (Senior and Thomas, 2005).
The refining activities in VNC, responsible for processing the feed into nickel oxide, will cease from April 2020 onwards, as part of the process to improve short-term cash flow. With this flowsheet simplification, VNC's nickel product mix will be solely comprised of nickel hydroxide cake.
a high Ni:Co ratio, sufficient to satisfy cobalt purity requirements for LME Grade Nickel. This extraction is achieved using a synergistic mixture of Versatic 10 and LIX 63. There are two basic steps involved, as in any solvent extraction process: extraction and stripping.

Production. The making of Nickel is a process which involves a number of steps. Mining. Nickel mined from lateritic ore is mined from various depths beneath the surface using large earth-moving equipment. The other nickel containing type of ore, sulfidic ore, is usually found in combination with copper ore and is mined underground.
Processes. Copper is found in natural ore deposits around the world. This page explains the production route taken from extraction of ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.
