Following the general design steps of nonferrous metallurgy workshop, the present situation of the APT production was first presented. According to the characteristics of the raw material , technological process of soda(NaCO3) leaching at high pressure—ion exchange—selectively precipitation to separate Mo—evaporation and crystallization process was selected as the process of APT production. The quantity of various materials in every process were fixed up and the corresponding equipments were designed or selected(include the type, size and number) originated from the result of calculating of the balance of metal and matter. The workshop is reasonably designed. The strategy of dealing with the industrial waste was proposed following the analysis of the source and the harm of the waste. The work force was arranged according to the requirement of producing process. At last, the economic target was analyzed. All these results shows that the process of this design is reasonable and economical. Keywords: scheelite-wolframite mixed concentrates; soda leaching at high pressure; ion exchange; ammonium paratungstate. 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc4299 摘要 PAGEREF _Toc4299 3 HYPERLINK \l _Toc30554 第一章 文献综述 PAGEREF _Toc30554 10 HYPERLINK \l _Toc10410 1.1 钨冶金的原料 PAGEREF _Toc10410 10 HYPERLINK \l _Toc7281 1.2 钨行业概
