Laterite nickel
The Yuanjiang deposit is the largest lateritic Ni deposit in China with proven reserves of 21.2 Mt at > 1.05 wt % Ni, and it also represents the second largest Ni producer in China. This deposit contains six ore districts: Bailadu, Jinchang, Anding, Longtan, Mengli and Midi. These ore districts are scattered along the Ailaoshan ophiolite belt and are spatially related to different ophiolite remnants. Among them, the Anding and Jinchang ore districts are the main mining parts of the whole deposit. The Jinchang ore district is located within the outcrop area of the Jinchang ultramafic body, which is 15.6 km long and 0.4–1.93 km wide. The Anding ore district is located to the southeast of the Jinchang ore district, where the Anding ultramafic body is exposed in an area 7.2 km long and 0.3–0.8 km wide. Approximately 20–50% of the ultramafic bodies are covered with regolith, which provide the host of lateritic Ni ore.
