Large Grinding Mill Make the Asbestos Tailings Waste to Treasure

In recent years, Aksay Kazak Autonomous County in Gansu Province actively implement the " project-driven " strategy, the project construction, continue to strengthen resource conservation and sustainable economic development . For the region of large reserves of asbestos tailings situation , and actively introduce large milling machines and other mineral grinding equipment , the new three conservation and utilization of mineral resources in economic and social development projects , improve the comprehensive utilization rate of associated minerals , making money is not a value of asbestos tailings waste to treasure .

Projects include: one , efficient utilization of asbestos tailings project . The project Aksai County asbestos mines, asbestos tailings as raw material, production of ultra-fine grinding mill grinding magnesium hydroxide , superfine white carbon black, iron hydroxide , lightweight building materials such as high-quality products . A total investment of 98.71 million yuan project , after completion , can produce 7,000 tons of magnesium hydroxide superfine , ultrafine grinding 6,400 tons of silica , the sales income of 178.2 million yuan , profit 57.85 million yuan .

Second, 20,000 tons superfine heavy calcium carbonate grinding processing projects. The project Aksai County asbestos mines, asbestos tailings serpentinite as raw material, the use of large Raymond mill and other crushing machinery for processing. The total investment is 7,647,900 yuan , from August 2005 to carry out preparatory work since, has completed the feasibility study , environmental impact assessment report preparation , has been reported to the Provincial Development and Reform Commission .

Third, wet asbestos tailings recovery process industrialization demonstration production line. The project is the recycling of asbestos can not be used in the production process of gravity flotation mill was abandoned asbestos dust . The project plans to invest 34.758...
