As mentioned previously, some (but not all) limonitic laterites are suitable for Class 1 nickel production. This is not the case for saprolitic laterites nickel produced from this style of deposit feeds into the stainless steel industry as Class 2 nickel. Laterite deposits are typically large, low-grade, and extracted through shallow mining. Chat
Mar 20, 2019 The laterite nickel ore is complex in composition and can be roughly divided into two types limonite type and silicon magnesium-nickel type. The main elements are nickel, cobalt and manganese. The laterite mining method generally uses open-pit mining. The ore body generally does not require rock drilling or blasting.

The laterite ores are mined through applying earth-moving operation techniques. Usage of large shovels, draglines to extract the nickel-rich layers and disposing the waste materials that comes in hand is the process at large which is carried out. The next stage requires the mined ores to be loaded into trucks and then hauled to the smelter.

Oct 01, 2010 In general, Ni production from sulfide ores involves either open cut or underground mining, followed by concentration via flotation, smelting of concentrates to produce a Ni ( Cu) matte, then refining to produce a pure metal. It is common for mines, smelters and refineries to be in different locations, depending on regional geographic factors.
Feb 15, 2021 Laterite ores (limonite and smectite) make melting-grade nickel. Processing of saprolite involves drying, calcination and smelting. Limonite and smectite processing involves high temperature acid leaching and refining. Sulfide ore processing involves concentrating, smelting and refining.
ores naturally occur close to surface, economical open pit mining techniques are employed to recover the ore after removal of the overburden (Moskalyk and Alfantazi, 2002). Laterite deposits typ-ically occur in layers, ranging from zero to 40 m in depth below the surface. Greece is the only EU country with extensive but low-grade nickel laterites.
