    News: As an annual production capacity of more than 3 million tons of the world's
    tumium dioxide
    production country, "13th Five-Year" period of China's titanium dioxide industry development is particularly concerning. "In the longer term, chlorination and sulphuric acid production processes will coexist, the industry will be more stringent environmental regulations and norms, mergers and reorganization efforts will be intensified, and speed up international integration." At the 2015 China (Deyang) phosphorus titanium chemical green development high-end forum held on December 8-9, experts on the future trend of the titanium dioxide industry has made a judgment.
    chlorination method is the mainstream of titanium dioxide production technology in the world, representing the direction of industrial development. However, due to the lack of titanium ore resources applicable to chlorination process in China, it is necessary to import titanium raw materials at high prices, chlorination process has not been able to break through the technical and economic ceiling, the production line after many years of research and development has not been fully opened. Fu Onejiang, deputy secretary-general of the titanium dioxide industry branch of China
    Coatings
    Industry Association, said that in this situation, the titanium dioxide industry should, on the one hand, vigorously research and development of chlorination process, so that it matures as soon as possible;
    Bi Sheng, director of the Titanium White Branch of the National Chemical Industry Productivity Promotion Center, also believes that chlorination technology, in addition to the process is not perfect, the investment of more than 1 billion yuan and billions of yuan is also daunting. Whether it is the introduction of technology, or independent research and development technology, chlorination process has not solved the key core technical problems, to form industrialization and scale is still some time.
    many difficulties encountered, but some experts are still optimistic about the development prospects of domestic chlorination process. Xu Xingrong, deputy chief engineer of Donghua Engineering Technology Co., Ltd., believes that the "Petrochemical Industry Pollutant Emission Standard", known as the most stringent in history, will be implemented in existing enterprises from July 1, 2017, which has more severe restrictions on existing titanium dioxide enterprises with sulfate method, and the chlorination process will usher in an opportunity for development. He also pointed out that at this stage, the development of chlorination process should be advanced application, sound and reliable as the first choice, new equipment must effectively reduce construction investment, but also pay more attention to the "three waste" governance.
    and the key to the development of titanium dioxide by sulphuric acid is clean production and circular economy. Such as Sichuan Longyu Group relying on the rich iron and titanium resources in Panzhihua area, accelerate the development of circular sulfuric acid titanium dioxide process, resource utilization rate continues to improve, energy consumption has dropped significantly. Zhou Xiaokui, vice president of the group, said that the sulfuric acid method titanium dioxide powder has a unique quality performance, in the future for a long time will also be the mainstream varieties in China, so to accelerate the realization of sulfuric acid method titanium white powder waste resources comprehensive utilization and clean production.
    experts believe that increasing mergers and reorganization efforts, speed up international integration is a major development trend of the titanium dioxide industry. It is inevitable that the number of producers will be smaller and the size of individual producers will become larger and smaller. Fu Said that in 2014, the top six producers in the titanium dioxide industry accounted for 40.8% of the country's total output, and the concentration of the industry increased significantly. During the "13th Five-Year Plan" period, the progress of reorganization and merger will be accelerated, and a number of key enterprises with greater development potential and world influence should be built. Bi Sheng believes that under the dual pressure of market and environmental protection, some small and medium-sized enterprises of 100,000 tons/year, especially 50,000 tons/year or less, will gradually fade out.
    chlorinated titanium dioxide production process is a green process, but also the world's titanium dioxide production technology mainstream process, but China's lack of matching titanium resources, must be high prices from abroad to import titanium raw materials, seriously restricting the development of chlorination process. In recent years, a group of scientific research institutions represented by Angang Group's Research Institute are committed to the process of chlorinated titanium dioxide "eating" domestic raw materials, and have achieved gratifying results.
    Such as Angang Group Research Institute to Sichuan Panzhihua titanium iron ore as raw materials for the development of titanium slag upgrade processing process, to solve the chlorinated titanium dioxide process of the "water and soil do not accept" problem has brought about a turnaround. They take titanium ore as raw material in Phangxi region, through the titanium slag upgrade process to obtain high-quality titanium-rich materials, its titanium dioxide content of 88% to 95%, silicon dioxide content of less than 2.5%, calcium oxide less than 0.15%, magnesium oxide less than 1%, composition indicators and particle size to fully meet the raw material requirements of the boiling chloride titanium dioxide production process.
