Strip mining is the most common technique adopted for nickel mining and statistics show that stripping of 500 million tonnes of overburden had to be removed to extract nickel ore, which amounted to clearing an area of 20 hectares (49 acres) per million tonne (five million tonnes of ore per year generate 25 million tonnes of tailings).
The local nickel industry is dominated by the French company Erametwhich has a 60% interest in its nic

The mining of laterites is basically an earth moving operation, with large shovels, draglines, or front end loaders extracting the nickel rich strata and discarding large boulders and waste material. The ore is loaded into trucks at the face, as would be the case in an open pit, and hauled to the smelter.

Mine wastes management Mining wastes is generated during the process of extraction, beneficiation and processing of minerals. Extraction is the first phase that consists of the initial removal of ore from the earth. This is normally done by the process of blasting, which results in generation of large volume of waste (soil, debris and other material). This is useless for the industry and is

Nickel in a circular economy. The concept of a circular economy is generally understood to be quota regenerative system in which resource input and waste, emission, and energy leakage are minimised by slowing, closing, and narrowing energy and material loops.This can be achieved through long lasting design, maintenance, repair, reuse, remanufacturing, refurbishing, and recycling 1.
