Italy uses physical separation to enrich TiO 2 contained in fine waste produced in the sulfuric acid treatment of titanium pigment plants. The main component of this waste is TiO 2 : 42.0 %, of which 30 % is soluble (TiO 2 , s) and 12% is insoluble (TiO 2 , i); SiO 2 : 25%; Al 2 O 3 : 6 %. 90% of this material has a particle size of <45 μm. This sludge was subjected to re-election and magnetic separation tests in order to enrich and reuse TiO 2 , s. The TiO 2 obtained by the flotation method is sent to chlorination to produce TiCl 4 . These brush machines integrate the functions of drilling holes and tufting fibers together. On the basis of international cutting edge brush making technology and our own patented inventions, Haixing brush machines have been well recognized in China and abroad. Modular designs are adopted, and all the key components are of famous brands, or imported products. PLC touch screen control, easy and quick brush programming, standardized components, optional brush platforms, enable a stable and easy operation, and a convenient maintenance. Every machine is dedicatedly manufactured to satisfy customers' high requirements of quality standard. And dust suction unit is included to remove dust and waste material and keep the machine clean.
