The recovery of ultrafine minerals has always been a world - class problem in the field of mineral processing. To improve the titanium resource recovery rate, concentration conquer thetime "technology, mining companies have free-standing self-improvement as a national strategy to support the development of science and technology, since 2012, with the domestic scientific research institutes, the ultrafine grained titanium iron ore recovery technology joint research, based on a large number of research literature, carried out the new process, new equipment, new drug development and testing.
The research team experimented, analyzed data, looked for clues, and discussed the best process. After hundreds of technological breakthroughs, a new recovery process of ultra-fine ilmenite with high efficiency and energy saving has been successfully developed. Three national invention patents, including "Beneficiation Method of Ultra-fine Ilmenite", were proposed and formed. As an important supporting project, ultra-fine ilmenite recovery has been listed as a key RESEARCH and development project in Sichuan Province in 2021.
In order to transform scientific and technological achievements into product advantages as soon as possible and lay the foundation for industrialization, the mining company built 10,000-ton industrial test line in 2021. The industrial test has achieved good results. The new process and new reagent have good adaptability to recovery of ilmenite with particle size less than 38μm, and the overall recovery rate is more than 50%. The recovery rate of ilmenite with particle size less than 19μm is over 90%, and the recovery of ultra-fine ilmenite has achieved a major breakthrough.
In April, the mining company ultra-fine ilmenite high efficiency recovery demonstration line construction project of the first phase of the project commencement ceremony held in Xingmao Company. This marks that the industrialization of ultrafine ilmenite ore dressing process has entered the substantial stage and a new breakthrough in ultrafine ilmenite recovery technology has been achieved. Recycling will be completed and put into operation after the demonstration line each year more than 100000 tons of ultrafine grained titanium concentrate, the economic benefit of 150 million yuan, not only solve the ultrafine grained titanium iron ore industry recycling worldwide problem, promote the depth development of vanadium titanium magnetite resources in panxi region, but also to the nation and the world of ultrafine grained titanium iron ore efficient recycling industry play a good demonstration effect.
