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.

Nickel and cobalt are predominantly produced via the beneficiation and pyrometallurgical processing of nickel sulphide ores, and hydrometallurgical processing of nickel laterite ores. Nickel is recovered either as ferronickel (FeNi) from saprolite ores or as an intermediate mixed sulphide/hydroxide from limonite ores. Cobalt is recovered from nickel ores during the refining process of the
