Panxi vanadium-titanium magnetic iron ore in addition to iron, associated vanadium, titanium, chromium, cobalt, nickel and other metals of strategic importance, high economic value. However, due to the complex nature of the ore, the utilization rate of the associated component titanium has been low. After decades of continuous research, the utilization technology of titanium in Panzhihua Iron and Steel Co., Ltd. has made great progress. How to further improve the utilization rate of titanium resources has become an urgent problem.
The Institute of Mineral Comprehensive Utilization of the Chinese Academy of Geological Sciences inspected the existing process of the Panzhihua Iron and Steel Plant, and concluded that it is necessary to improve and improve the process from the perspective of process mineralogy, and improve the existing process and improve the current process of the Panzhihua Iron and Steel Plant. The utilization of titanium is the most beneficial; fundamentally identifying the problem is also the most significant for the advancement of titanium utilization technology.
The project collected 228 process samples, 90 class samples, and 76 process mineralogical samples for the current process of the selected titanium plant, covering the current process of the titanium plant and the raw materials and intermediate products of each production section and each workshop, and the tailings. The samples taken are representative of the samples taken. Through a large number of detailed process mineralogical research and analysis on hundreds of samples, the ways and means of loss of titanium recovery rate in the first eight, the eighth, heavy electricity, shake selection, filtration, etc. Based on the yield, grade and recovery rate of concentrates and tailings and intermediate new products in each production section, the theoretical recovery rate of magnetic tails was obtained, which provided basic data for the next technical transformation of the titanium plant and compiled Select the titanium number quality flow chart.
After conducting on-site process inspection of the project and diagnosing relevant production problems, Pangang Company relied on the report as a technology, investing more than 200 million yuan to carry out technical research on the original titanium plant, and completed the technology in 2010. Changed, titanium recovery (for magnetic tail) increased from 17% to 35%. The research results won the first prize of Sichuan Science and Technology Progress Award in 2011.
