2010 China Nonferrous network - non-ferrous metal authoritative media platform Huatailong Tibet Mining Development Co., Ltd. completed Jiama copper polymetallic ore copper-molybdenum separation test key technologies industry its application projects in Lhasa by China gold Association organized scientific and technological achievements. China Nonferrous network. Identification of the view that the overall technology has reached the international advanced level in the high-altitude alpine ecologically fragile zones copper-molybdenum separation technology has reached the international advanced level of similar mines has a demonstration effect. China Nonferrous network.
Huatailong company started in 2012 copper-molybdenum plating separation test work, the establishment of scientific and technological research and development group, to overcome the cold and oxygen, mineral composition of the ore complex, six kinds of valuable elements in mutual interference, backwater need to recycle all of the plateau low pressure is not conducive to flotation, six kinds of valuable elements separation is difficult, inexperienced young research team, no experience to draw on all the difficulties, positive innovation, based on the number of tests, on April 26 this year, start a copper-molybdenum separation industrial test and industrial production. China Nonferrous network.
July 20, copper-Molybdenum tube separation of industrial production has made advanced technical indicators to achieve a grade standards, and solve the concentrate filtration and backwater fully utilized and other issues, marking the successful separation of copper and molybdenum. China Nonferrous network.
Technical appraisal committee of experts through on-site field trips, after listening to the project team thematic technical reports, access to relevant technical information, as well as questioning the respondent, after appraisal, the project's scientific and technological achievements made to give a high evaluation. China Nonferrous network.
China Gold Association vice president, secretary Zhang Bingnan said copper-molybdenum separation of scientific and technological achievements, the other mines in the gold industry to promote the use, boosting the entire gold industry and the level of technology in Tibet has leapt to a new level, and for China's non-ferrous metals leading the development of the industry has made a contribution of
Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.
