The early 1980s, China molybdenum smelting capacity of less than 20,000 tons / year, of which molybdenum smelting enterprises are mostly small, scattered around, backward technology and equipment, a single product, the majority of molybdenum iron production capacity of 500 tons enterprises / year , independent existence of molybdenum oxide, molybdenum and iron baking refineries more.
The early 1990s, Chinese molybdenum oxide, molybdenum iron smelting enterprises developed rapidly, with more than 200 molybdenum oxide, molybdenum iron smelters, almost molybdenum concentrate production of molybdenum oxide and molybdenum place has iron smelters, oxidation independent existence molybdenum, molybdenum iron smelter more, molybdenum oxide, molybdenum and iron smelting capacity is much larger than molybdenum concentrate production capacity, especially in Liaoning Province, Henan Province, this phenomenon is more prominent, smelting capacity has reached 70,000 tons / year .
In the 21st century, the Chinese molybdenum oxide, molybdenum roasting scale smelting iron has made significant development, especially in recent years, China Molybdenum has been considerable development, with the expansion of production scale upgrade of molybdenum ore, molybdenum smelting capacity has been greatly improved, there are mostly molybdenum mineral enterprises to establish a supporting molybdenum smelting facilities. Many local small molybdenum processing plant were integrated to build a larger scale molybdenum smelter, while in the Northeast and many independent Luoyang molybdenum smelter was forced to stop. Chinese molybdenum oxide, molybdenum iron baking refining capacity from 20,000 tons the early 1980s / year to more than 2008 of 200,000 tons / year, an increase of 900%, molybdenum smelting scale over which 5000 tons / year longer minority. Now Chinese molybdenum oxide, molybdenum iron baking refining capabilities are to large-scale development, especially in the two major domestic molybdenum joint venture --- Jinduicheng Molybdenum Group Co., Ltd. and Luoyang Molybdenum Molybdenum Group Co. were roasting capacity more than 20,000 tons / year, also is expanding its production scale.
