Country, "August", "during the" science and technology research, joint research by the Shizhuyuan non-ferrous metals company, Beijing General Research Institute of Mining and Metallurgy, Guangzhou Nonferrous Metal Research Institute, Changsha Nonferrous Metallurgy Design and Research Institute and other units, is proposed to trunk full floating process based, chelating agent, a flotation collector core can float molybdenum and bismuth, bismuth is selected from sulfur mix, black scheelite flotation, selection of heating crude concentrate, fine mud flotation wolframite The new technology of comprehensive mineral processing - the persimmon garden method. Its core technology - "Tungsten-molybdenum-bismuth complex polymetallic ore comprehensive beneficiation new technology - persimmon bamboo garden method" won the second prize of the 2001 National Science and Technology Progress Award. On the basis of the “Shizhuyuan Lawâ€, Guangzhou Nonferrous Metal Research Institute, Beijing Research Institute of Mining and Metallurgy, and Shizhuyuan Nonferrous Metals Co., Ltd. have thoroughly investigated and determined the technological innovation direction of tungsten ore dressing , which has been obtained after more than ten years of research. A major breakthrough, creatively proposed the black and white tungsten mineral split flow rate, asynchronous beneficiation separation theory and new technology, scheelite flotation combination new agent and collector enhanced re-adsorption - tri-alkaline selective desorption and drug removal direct selection, etc. The new technology has been widely used in Hunan Shizhuyuan Nonferrous Metals Co., Ltd., Hunan Nonferrous Metals Co., Ltd. Huangshaping Mining Branch, Gansu Xinzhou Mining Co., Ltd. and Ninghua Xingluokeng Tungsten Mine Co., Ltd. Technology - "Key technology and industrial application of high-efficiency separation of complex and difficult to treat tungsten ore" won the second prize of National Science and Technology Progress Award in 2014.
LINA Pressurized Dispersion Kneader
LINA high pressurized dispersion kneader is used for a variety of materials including high filled rubber, plastic and rubber plastic compounds. LINA dispersion kneader's mixing chamber is specifically designed for materials that need high pressure and enclosed mixing environment. Materials are kneaded intensively by a "M" type pressure lid, so the polymers are bonded with fillers more effectively and improving the filling ratio.
Working principle of LINA's "M-W" type mixing chamber
M-W pressing and molding mixing chamber of LN dispersion kneader is applied to ensure good abrasion resistance and even mixture of materials and optimized change of physical nature. 2-turning design is applied for leakage-proof device to largely enhance leakage proof performance, and the built-in dust collector allows for convenient and quick collection of dust.
The mixing chamber is made of advanced special steel, with surface treated with abrasion resistant steel, coated with hard chromium to provided excellent abrasion resistance and its service life 1-2 times longer than traditional dispersion internal mixer. The mixing chamber is divided into tipping type and lifting type. Dry mechanical shaft seal is used to ensure easy maintenance and environment protection.

Progress in tungsten ore dressing technology and equipment
In 2009, the Beijing Research Institute of Mining and Metallurgy established a research group headed by Academician Sun Chuanqi, and conducted research on the sub-topic of "China's Tungsten Industry Development Status and Countermeasures Research" (mine mining and selection). The research team distributed the “China Tungsten Mine Resources Development and Utilization Survey Form†to domestic tungsten enterprises. At the same time, in July and September 2009, two research groups consisting of mining, mineral processing , mineral resources and environmental protection were organized, and many companies in Jiangxi, Guangdong and Hunan conducted on-the-spot investigations. Investigate and obtain a large amount of first-hand information, and wrote a report on "China's Tungsten Industry Development Status and Countermeasures".
