Lead-zinc mine, is rich in mineral metal elements such as lead and zinc, lead and zinc wide range of uses, can be used in the field of electrical industry, machinery industry, military industry, metallurgy industry, chemical industry, light industry and pharmaceutical industry. In addition, lead metal has many uses in the nuclear industry, petroleum industry and other sectors. China's lead-zinc mines are mainly concentrated in Yunnan, Inner Mongolia, Gansu, Guangdong, Hunan and Guangxi. Before conducting the ore optional test, the ore material composition should be studied first, the ore type should be classified, the state of occurrence of the element should be ascertained, the mineral type, the ore structure and the grain size characteristics of the ore should be identified, and a reasonable process flow should be provided for the ore dressing test. in accordance with. There are many types of lead-zinc ore, and the classification criteria are different, and the types are different. According to different ore structure, it can be divided into disseminated ore, dense block ore, breccia ore, strip ore, fine vein disseminated ore. Press different ore useful components, can be divided into lead ore, zinc ores, zinc ore, copper, lead and zinc ores, sulfur, lead and zinc ores, copper, lead and zinc ores sulfur, tin-lead ore, lead ore, antimony, zinc, copper ore and the like Divided into sulfide ore, oxidized ore, mixed ore according to the degree of ore oxidation.

Lead-zinc ore generally has to be refined and concentrate to concentrate lead and zinc metal products. The ore technology processing and smelting test is an important part of geological exploration work and one of the important basis for evaluating whether the deposit can be used for commodity ore development. Therefore, the ore optional test must be carried out during the geological exploration process.
The type of ore of lead-zinc ore is different, and the beneficiation methods and processes used are different. The oxidized ore is flotation by flotation or re-election with flotation, or after flotation by sulphide roasting, or after re-election, treatment with sulphuric acid and then flotation. Sulfide ore is usually floated. For lead-zinc ore containing polymetallics, a general beneficiation method such as magnetic-floating, heavy-floating, heavy-magnetic-floating is generally used.
Optional test and beneficiation process of lead-zinc ore
Teflon Washer with the most uprising characteristics as below:
A.Resistant to many chemicals, includes ozone, chlorine, acetic acid, ammonia, sulfuric acid and hydrochloric acid.
B.Weather and UV resistance
C.Non Stick::Very few solid substances will permanently adhere to a Teflon coating. While tacky materials may show some adhesion, almost all substances release easily.
D. Outstanding performance at extreme temperatures to meet your special temperatures 'demands: it can temporarily withstand temperatures of 260C and cryogenic temperatures of -240C and still with the same chemical properties. Its initial melting point of 342C (+- 10C) & second melting pint at 327C (+- 10C).
