Utilization of non-ferrous tailings progress
Mineralized clinker agent research and development. Has made many achievements. _12 Election re-election of a joint ; extraction of indium, cobalt, gallium and other rare metals factories,[link widoczny dla zalogowanych], mines are increasing: Hebei, the Ministry of Commerce editorial from a tungsten tungsten ore flotation tailings recovery of new technology, the use of Sec countercurrent leaching and ion exchange separation of impurities in high availability ammonium solution of pure tungsten, the key is the decomposition of minerals and crude Preparation of pure sodium tungstate solution, ammonium tungstate; in principle, the Jie and Ai-Xiang Wu Ultrasound and other research to reduce the leaching of copper tailings leach copper mine tailings in the new cycle technology, the results confirmed that: the formation of a strong ultrasonic agitation can promote solute diffusion: its role in the micro-cavitation bubbles burst and the formation of shock waves, micro jet, solid surface has an impact on the damaging effects can be produced by the reaction of the cover removed, conducive to hole crack development and the formation of new reaction interface, in particular the role of weak agitation leaching reach recovery of the tailings pipeline ultrasonic leaching technology. I, should be noted that, with the Tailings building materials Zengyin suspect the impact of radioactive and other harmful substances in the health market is not good. did happen to do adobe built in the tailings house problems not receiving television programs, to identify which is produced by screening the tailings with high iron content due to: live in the place of yellow sand tailings system with cement mortar and concrete room built for people, who have had the same can not explain the disease. So experts advise: building materials with tailings system needs special care, the existence of a detailed analysis of tailings material and adverse to human health; the composition of the tailings should not be used against the main development direction of building materials. _2 Fourth, Tailings by Cai Delong Group Silicon Shen Hong, Zhang Yulong idea: molybdenum tailings SiO. as a basis, supplemented with Ca, Mq, comprehensive utilization of the K, MO, Fe, Zn system contains a variety of trace elements of silicon. in 2OO5 in cooperation with the Heilongjiang Institute of Geology of silicon with a molybdenum mine tailings to achieve better development results. made by the field experiment showed that: rice blast resistance is strong, an increase of 3% ~ 2O.5%, rice taste Well, a slight decrease total cost of pesticide fertilizer: maize drought resistance, an increase of 45.5%; enhanced pest-resistant vegetables, fruits and fruit quality improved significantly increase, good quality, color depth, resistance to storage,[link widoczny dla zalogowanych], the average yield of 40 %. 5O million tons of annual output of silicon to build a business, to 2.5 billion yuan of output value and employment opportunities for thousands of people. of molybdenum sustainable development of enterprises and social economic benefit. ��.
