The laterite nickel ore at Goro is composed of two layers–limonite and saprolite–between a cover of leached material and the bedrock below. The 10-20-m-thick cover has its own two layers: brittle iron oxide crust covers a high-hematite zone. Beneath these is the 10-m-thick limonite layer, which grades about 1.5% Ni. Then there is a cobalt- and manganese-enriched zone. Below all …

MURDOCH RESEARCH REPOSITORY

A review has been completed of current and proposed processing technologies for nickel laterite ores. Although future supplies of nickel depend on laterite ores, their processing is inherently energy intensive and expensive as, unlike sulphide ores, they cannot be significantly upgraded, meaning the entire ore needs to be treated in the process. In addition, hydrometallurgical processes …

How clean can the nickel industry become?

On top of that, with nickel being one of the most technically challenging metals to process and refine, and every operation being unique, further challenges will also be asset dependent (Exhibit 1). For miners, the type of ore deposit—sulfide or oxide (or laterite, further subdivided into saprolites and limonites)—defines the whole value chain.
