China's large molybdenum mining based mainly on open-pit mining, the use of large heavy machinery. In this way a high efficiency of the ore waste is low. Small and medium sized mines generally use underground mining, which mines with low molybdenum content, not suitable for the use of large machinery, mining lower than, the amount of waste ore is relatively high.
At present, China Molybdenum mine development problems in the following:
(1) Luancai severe deforestation. Our high grade molybdenum ore, easily mined, each competing private miners mining, currently, more than 400 large and small enterprises, "eating" with our Molybdenum market, and the Chinese side by side in front of the world's molybdenum reserves of the top three U.S. and Chile, companies are not engaged in this field to 10. Luancai deforestation serious, serious waste of resources, resulting in unnecessary losses and residual lean ore mine.
(2) have not been associated minerals reasonable use. Our multi-molybdenum mine is a composite multi-metal elements, associated minerals component complex, but because the process is not high technology, multi-refining or recycling is not in the molybdenum mining for other metals.
(3) deep-processing technology is low. China's exports of molybdenum and molybdenum products are raw materials, or low-end products, relatively simple, not much high-tech molybdenum products, such as flame retardants, the country can not be mass-produced ammonium molybdate. After molybdenum exports are mainly used in the production of special steels, catalysts, etc., while production of high quality steel and alloys are very small or almost no production. Although the status of long-term low-cost foreign sales of rare earth different country in the Molybdenum market gradually turn from a net exporter to a net importer, but still conceal the role of the conversion of the world's molybdenum-iron "factory" embarrassment.
