Titanium reserves in China ranks first in the world, but 95% are hosted the native vanadium titanium magnetite, are mainly distributed in the Panxi area; followed ilmenite the placer, mainly distributed in Yunnan, Hainan, Guangdong and Guangxi region. Abundant titanium resources in Yunnan Province, with easy mining, you can get a better quality of titanium concentrate by simple beneficiation process but the current situation is the low recovery rate, serious waste of resources. Yunnan Metallurgy Group Co., Ltd. as the leading enterprises in the nonferrous metals industry in the province, Yunnan Xinli Nonferrous Metal Co., Ltd., its subsidiary companies to undertake the important task of the titanium industry development. 80,000 tons / high titanium slag, 60,000 tons / year chloride process titanium dioxide, 10,000 tons / year of titanium sponge major projects have started construction, to achieve substantive results, currently 5000 t / titanium project construction also planned. Large DC electric arc furnace smelting titanium slag project has been put into operation, using a DC arc furnace smelting titanium slag into the furnace grade requirements (TiO2 grade gt; 47%), for the full and effective use of the company's existing resources of titanium. Necessary titanium concentrates production status, site transformation and production of new technology in order to meet the titanium slag smelting necessary raw materials and increase the recovery rate at the same time, make full use of the resources. The company belongs to of horse beans ditch titanium mill using the traditional joint \Through the production process to examine the titanium mill site, the titanium mill the titanium concentrate TiO2 grade of 46.37%, the recovery rate of only 35.09%; same time, to identify the problems in the production process and to propose measures for improvement and solution. The problem exists for the processing plant, the on-site production process optimization and transformation after transformation, the titanium mill titanium concentrates TiO2 grade of about 45%, TiO2 recovery rate has increased 13% percent to increase the production of titanium concentrates. At the same time, the thesis of the titanium ore processing plant as the research object, aims to improve the TiO2 recoveries, to change the traditional \Based on mineral magnetic differences in process mineralogy using magnetic separation magnetic mineral elected pre-tailing the tailing was 70%, to get the titanium rough concentrate TiO2 taste up to 22%, the total recovery of titanium about is around 93%. Titanium rough concentrate single re-election the single intensity magnetic separation, the single flotation and the re-election - magnetic joint selection trials, the final joint process of \Raw grade ore joint process of re-election - magnetic, magnetic tailing - the resulting titanium concentrate TiO2 grade of 47.14%, 62.86% recovery rate; meet the large-scale DC arc furnace smelting titanium slag and greatly improve the recovery, to provide a test for the new titanium processing plant construction.
