1、The mineral processing technologies and zinc Lead-zinc ore dressing to pass commonly integrated concentrates smelting rich can lead, zinc metal products. Ore processing technology, the geological exploration of dressing-metallurgy test is an important part of work, can make merchandise of evaluating

2、 the important basis of mineral exploitation, therefore in the geological exploration process must undertake mineral optional experiment. In the early stage of geotechnical investigation or should do, optional lab test, in the early stage of detailed geotechnical survey or to do a detailed optional

3、experiment. When the ore composition, and have huge complex comprehensive utilization value of large and medium-sized, argillation or new type mineral, except for detailed experimental optional when necessary, the expansion of the scale of laboratory tests made. For some types of ore dressing method

4、 is not qualified with product or unable to concentrate more on single separation test lab. Smelting. In ore optional tests shall be carried out before the first deposit ore composition, ore type and find out the occurrence, mineral elements identified species, ore structure and disseminated extent

5、characteristics Dressing experiment formulate rational process, provides the basis. Lead-zinc ore industrial division, is based on the natural types in mineral ores, according to different levels oxidation (lead or zinc sulfide oxidation rate oxidation rate 30%), mixed ore (lead or zinc oxide rate i

6、s 10% 30%). According to the different components of useful ore can be divided into the lead, zinc ore mineral zinc ore, lead, zinc, copper, lead, zinc sulfide ore mineral zinc sulfide ore, copper, lead and tin lead, zinc, copper ore sanyanghuaerti, etc. According to the different structure and mine

7、ral ores, can be divided into huolulingjiao-pengwu dense clumps ore, brecciated minerals, mineral, fine veins banded huolulingjiao-pengwu ore, etc. When the need according to the types of ore mineral intergrowth, mining, sorting, and promotes (in geological section to circle, and adjacent profile ca

8、n be connected, the corresponding circle the distribution, and separately calculated reserves. According to the dressing experiment, lf different types of ore dressing, choose a different approach. Commonly used method of sulfide ores flotation. Oxide ore in flotation or re-election, or jointly with

9、 the flotation sulfide mineral after roasting flotation, or heavy after using sulfuric acid treatment again flotation. For many of the metal containing zinc ore, general use magnetic float, - - - - magnetic float, heavy floating jointly dressing method. Methods: smelting ore deposits is the main min

10、eral materials, lead the smelting method has dominated and wet. Currently dominated by wet method is given priority to, in the experimental research. Dominated by sintering lead smelting and roasting lighten pigmentation, smelting reaction smelting methods. Lead the refining mainly adopts refined, f

11、ollowed by electrolysis holds refining. LiuHuaXin concentration is the main mineral zinc, also have dominated and wet smelting. Dominated by distillation, refining vertical flat pot distilled or electric stove, The zinc leaching, nearly 20 years development, has become a major method of zinc. Domina

12、ted by distillation from coarse zinc zinc refining or direct application, But the zinc leaching income, high quality, electrolytic zinc without refining. For separating of zinc sulfide is mixed concentrate, generally USES and output of lead and zinc smelting process of blast furnace airtight. For se

13、parating of zinc oxide extremely difficult mixed ore, China has a unique treatment method, zinc oxide ore mines or its enrichment of hybrid product, the sinter or in a blast furnace, the melting to lead and zinc with coarse molten slag, slag furnace smoke in the smoking further and zinc oxide produc

14、t, and get wet zinc electrolysis zinc. In addition, still can use rotary kiln of zno products gain direct smoke. Our lead, zinc concentrate product contains rich associated in smelting process, comprehensive recycling, economic benefit has been considerable. When the lead smelting comprehensive recovery of copper and zinc sulfide, there, gold, silver, platinum group metals, bismuth, thallium, cadmium, selenium, tellurium, etc. Zinc
