China is very rich in resource of titanium ore, but the titanium dioxide industry is relatively backward. Panzhihua area is the important titanium mine base, the city encourages to carry out deep-processing such as the production of titanium dioxide. However, the production scale of existing titanium dioxide can not give full play to Panzhihua,s advantages in resource of titanium, the existing titanium dioxide product variety and quality can not meet domestic market demand, therefore, the present feasibility study (Pre-feasibility study) for draft-building titanium dioxide production project have greater practical significance at this stage. Through the research, the raw materials supply of project is stable and reliable ; the technology and equipment can reach the domestic advanced level; using of titanium slag and sulfur acid for raw materials, and equipping with waste acid concentrating, the problem of environmental pollution is solved; The total investment of the project is 76.25 million Yuan RMB, the net income for one year isYuan RMB, the payback period is 2.6 years; the item can be rapidly recovery costs, the economic benefits is feasible. Key words：titanium dioxide, project, feasibility study  目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc231552439 摘 要 Ⅰ HYPERLINK \l _Toc231552440 ABSTRACT PAGEREF _Toc231552440 \h II HYPERLINK \l _Toc23155244
