Which smelter in China produces platinum?

At present, the largest platinum metal producer in China should be Gansu Jinchuan Group Company, which mainly produces copper and nickel metals, and by-products such as gold, silver and platinum. Other smelting enterprises generally produce little platinum, because heavy metal minerals such as copper, lead and zinc contain little platinum, and gold production only produces a small amount of platinum, such as Zhuzhou Smelter, Shaoguan Smelter, Jinlong Copper and Daye Nonferrous Company.
