ABSTRACT：This design is based on "YunXi LvHuaFa" deal with difficult to choose lean tin separation middlings dominated the dust collecting process, precipitation, use of sodium chloride solution leaching ChuTuo chlorine, get certain humidity of chlorinated lead and tin ore concentrate. According to a given process flow, the design requirements, and calculates the annual production of every working procedure required quantity, and thus for the process of material balance and water balance, the aim is that keep temperature, ensure the mother liquor leaching solution of chlorinated lead not under the condition of crystallization precipitation filter, so as to reduce chlorinated lead into the flow of the leaching of washing load, reduce.
This design main task is to determine the type of equipment and model, the design of the main equipment, draw the main equipment in the industrial design, mixing slot connected graph and workshop equipment layout, among them, the workshop equipment arrangement and the design of the mixing slot is the focal point of design and core. In order to adapt to the development of China's modern tin industrial demand, but in line with the energy saving and obtain the biggest economic benefits, and the principle of environmental protection, the design of the factors as much as possible to adopt new technology, and strive to design more reasonable, convenient operation, the future for workshop good economic benefit is obtained lay the foundation.
