Aimed at promoting technological innovation bauxite and rare earth

November , on the Utilization of Mineral Resources , Institute of Geology, Chinese Academy of Sciences ( hereinafter referred to as "Chengdu Comprehensive house" ) , it is also a very productive day. With the " Guizhou Chongqing region of low-grade bauxite ore availability evaluation", " suspension calciner mine development" and a number of project results to adjust successfully passed the acceptance , the 2011 Chengdu Comprehensive Geological Survey carried out in all the items complete. Geological Survey project's successful completion , not only demonstrates that where technological innovations leading role model, but also greatly enhance the utilization of mineral resources as is the ability to provide technical support .

"This year , we are on the scientific and technological highlights outstanding , low-grade bauxite and oolitic hematite mineral processing research to get a breakthrough in the acceptance review meeting has been highly appreciated by specialists . Meanwhile, we also succeeded in 'going out' , for the first time signed a $ 1.5 million Australian rare earth mineral processing technology research projects. " The director of Liu Yachuan said excitedly.

We must first sharpen his tools. In the era of technological innovation has become the mainstream of development , comprehensive utilization of mineral resources, attention increasingly to social context , as the comprehensive utilization of mineral resources in the field of science and technology innovation an important support units , Chengdu is how comprehensive the forged "weapon " and play the role of a good leader to lead it ?

Targeting the " Big Five" minerals unwavering

As China Geological Survey Bureau under the central public geological survey team, Chengdu are mainly engaged in comprehensive evaluation of mineral resources , comprehensive research and development work . Built by nearly 50 years , the Institute has always adhered to the scientific and technological innovation for the legislature of the country, on the one hand and technological innovation, on the one hand the transformation, in the difficult to use iron ore, non-ferrous metals associated minerals , low-grade bauxite , " three dilute " the comprehensive utilization of resources continue to achieve new breakthroughs in research areas , firmly occupy the leading position in the development of China's construction Panxi vanadium-titanium magnetite , Bayan Obo rare earth niobium iron polymetallic ore, Jinchuan copper-nickel mine three ore as a symbol of a large resource base , provide a reliable technical support and strategic basic information , and to Yichang phosphate rock , manganese carbonate Xialei Guangxi , Inner Mongolia, Huanggang iron complex refractory low-grade tin and other new types of minerals from " difficult to use mine " becomes "available mine ."

"Chengdu Comprehensive have abundant human resources , technical resources, and so on. Over the years , the Institute has been committed to the field of research utilization of metallic minerals , which formed a large number of scientific research and innovation experience . Fortunately, this area played a leading role in technological innovation , Chengdu consolidation of responsibility. " Liu Yachuan Schmidt said:" However, the study was a comprehensive utilization of mineral resources involves many kinds of mineral resources and requires continuous innovation of systems engineering, not eyebrows beard grabbed , you must play to their strengths and expertise around the national shortage of minerals , to carry out targeted research and research. "

In fact, in early 2012 , the National Strategic Action prospecting breakthrough just started when the consolidation of Chengdu, Ministry of Land and China in accordance with the unified arrangements of Geological Survey to determine the main direction of his research - around the national shortage mineral and strategic resources , focus on strengthening difficult to use iron ore, non-ferrous metals associated minerals , low-grade bauxite , " three rare" resources , low-grade phosphate rock "five minerals ," actively engaged in prospecting breakthrough strategic action the main battlefield.

Difficult to use the comprehensive utilization of iron ore has been the study of the strengths. Over the years, the continuous innovation Chengdu comprehensive vanadium titanium magnetite and hematite oolitic utilization research, has been leading the development of the industry , and has attracted many Panxi and mining enterprises in Hubei Province concern. " Now, many mining companies are actively looking to come to , that our technological achievements, and asked for them to provide services on the beneficiation process . " Liu Yachuan said.

The inclusion of the China Geological Survey Bureau "2010 Top Ten Geological Survey Progress " and " western Hubei Ningxiang type iron utilization technology research " in recent years has made new breakthroughs , from the original re-election Desliming to magnetic off mud, mud off and then re- suspended magnetic roasting - magnetic separation - reverse flotation process , processing costs continue to decline . Plagued our country for many years worldwide problem - the use of oolitic hematite problems are gradually solved.

In recent years the Institute launched a " low-grade bauxite beneficiation technology" research is also news of success , following the success of selected " 2012 Top Ten China Geological Survey Progress " , this year Guizhou Chongqing region for low-grade aluminum bauxite beneficiation technology research has also made a historic breakthrough , the Al-Si ratio of 4 about the use of low-grade bauxite to become a reality.

The Utilization of Mineral Resources areas where scientific research strength , not only won the favor of many domestic enterprises , has also been recognized by multinational companies and foreign companies . Consolidation of Chengdu this year , it was undoubtedly the most landmark " three rare" beneficiation technology out of the country - the successful signing of a contract amount of 1.5 million dollars in Australian rare earth mineral processing technology research projects. And this is only the prelude to the door step . It is understood from the United States , South Africa, several companies are also to discuss some of its mineral beneficiation technology research projects.

"In doing domestic projects simultaneously , with the big companies, the project done abroad , establish an international brand , to improve the Chengdu comprehensive scientific and technological innovation , and expand development of great significance. " Liu Yachuan representation .

The reason why some well-known international companies , " election" in the Institute , fancy is their strength. But due to the different nature of foreign ore , implementing projects abroad is not easy.

" Despite the high grade rare earths in Australia , but the quality is low , it is difficult enrichment , beneficiation technology requires a higher than domestic . " The Institute 's deputy director in charge of research and Ping Yim said:" We want to play good in the technical aspects of rare earth mineral processing technology, to strengthen scientific and technological innovation, and strive to do a better job of foreign rare earth mineral processing projects , more solid , we establish brand.
