To extract nickel from the lateritic ore, conventional roasting methods are used, removing moisture. The nickel oxide is then separated by a reduction furnace, which in turn reduces the chemical-filled water. This metallurgical process results in a 75% pure form of nickel. 9. The extraction process of nickel from a sulphidic ore requires a ...

1. 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. Nickel from lateritic ore is extracted trough extractive metallurgy.

The heterogeneity and homogeneity of ore grades affect the accuracy of ore resource estimates. The mismatch of the variogram model causes the grade estimation to be inaccurate. This study aims to determine the accuracy of mineral resource estimation using spatial statistical analysis. The data in this study is the grade of nickel laterite ore.
