ABSTRACT:Graduate courses teaching the integrated design is practical teaching and is the content of the review and consolidation for the university learning. The design process is mainly around the rotary kiln refractory high temperature chlorination of tin in the ore produced by collecting the solution for extraction of valuable metals, for which the extraction of valuable metals, and iron salts with pre-and in arsenic removal, the and Sheen bismuth, cadmium, zinc and precipitation in the sub-step precipitation process. Design specification for the design of the process described in detail include: process calculation, equipment selection and design of the main device configuration design, process mapping, and device mapping. And introduced the plane selection, flat portfolio choice, the choice of materials and determine the specific approach and the main structure.
