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 sodium hydroxide(NaOH) 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 02024 年 6 月 23 日下载后可任意编辑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 w...
