CMOC or CMOC Group Limited (simplified Chinese: 洛阳钼业; traditional Chinese: 洛陽鉬業; pinyin: Luòyáng mù yè), previously known as China Molybdenum Company Limited,[3] is one of the world's largest producers of molybdenum, tungsten, niobium and cobalt.

Together with Ximen Tungsten Co Ltd, it founded a joint venture, Luoyang Yulu Mining Co. Ltd. to process the ore.[14][15] In August 2006, the company began planning an initial public offering, and, in preparation for the move, changed its name to China Molybdenum in 2007.

The Hong Kong Stock Exchange sanctioned the group for not publicly disclosing the Huqi acquisition in a timely manner.

[21] The scope of the offering was cut back from initial plans due to intervention from the China Securities Regulatory Commission.

[32] CMOC's three largest shareholders are the Cathay Fortune Group, Chinese battery manufacturer CATL, and HKSCC Nominees Limited, which own a combined 66.03% stake in the company.

[45] Similarly, through its subsidiary KFM Holding Limited, the company also acquired a 95% stake in the Kisanfu mine from Freeport-McMoRan in 2020 for a price of $550 million, which also produces copper and cobalt.

[46] In 2021, the group sold 25% of KFM Holdings to Contemporary Amperex Technology for $137.5 million, leaving it with a 71.25% stake in the Kisanfu project.

[50][51] The company specializes in the trade of copper, zinc, aluminium, nickel, cobalt, niobium and lithium.
