Copper Mine
Copper ore typically consists of aggregates formed by copper sulfides or oxides combined with other minerals. When reacted with sulfuric acid, it produces blue-green copper sulfate. Natural copper minerals exhibit a wide range of colors. Chalcopyrite appears bright yellow, while bornite is dark copper red and turns into a blue-purple mottled appearance after oxidation
DetailLead-Zinc Mine
Lead is one of the earliest metals extracted by humans from lead-zinc ores. It is one of the softest heavy metals and also one of the densest, with a bluish-gray color, a hardness of 1.5, a specific gravity of 11.34, a melting point of 327.4℃, and a boiling point of 1750℃. It exhibits good ductility and is easily alloyed with other metals such as zinc, tin, antimony, arsenic, etc
DetailMolybdenum Mine
Molybdenum deposits in China were first discovered in the late Qing Dynasty and began to be mined on the eve of the First World War. At that time, the main mining targets were some vein-type molybdenum deposits along the coast of Fujian and Zhejiang provinces, as well as some vein-type tungsten deposits associated with molybdenum in southern China
