A Brief History of Molybdenum Mining

The first molybdenum mine to be developed in the world was the Knaben deposit in the Kingdom of Norway. The mine began to mine in 1885, due to the demand for molybdenum at that time is very small, the mine when the mining time to stop. the second half of the 19th century, molybdenum is the first in the United States began industrial production, the annual output of only a few tons. since the 20th century, due to the demand for molybdenum increased year by year, molybdenum mining is also expanding year by year, the world of molybdenum's annual production growth is rapid, on the eve of the first world war increased to about 100t to reach the late 1930s The annual production of molybdenum in the world has been increasing rapidly.

China's molybdenum ore was first discovered in the late Qing Dynasty, began mining on the eve of the First World War. At that time, the main mining is some vein type molybdenum ore along the coast of Fujian, Zhejiang and some vein type tungsten ore with molybdenum in South China. At the end of the Anti-Japanese War, the molybdenum mine in Yangjiazhuangzi, Liaoning Province, was subjected to predatory mining by the Japanese invaders. The annual output before liberation was only a few tons, at most more than ten tons. After liberation, in order to meet the needs of China's socialist construction, has established a considerable scale of the three major molybdenum industry base (Liaoning Yangjiazhuangzi, Shaanxi Jinduicheng, Henan Luanchuan), as well as a number of small and medium-sized mines, many copper and tungsten mines are also recycled molybdenum associated with it, which makes China's molybdenum concentrate production jumped into the world's advanced ranks.
