the mineral processing technologies and zinclead-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 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 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 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 characteristicsdressing 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 is 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 mineral 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 can 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 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 mineral 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, followed 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. dominated 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 separating 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 product, 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 smelting of sulfur recovery when there, lead, copper, gold, silver, indium, gallium, ge, cadmium, cobalt, thallium, mercury, etc.铅锌的选矿与加工技术铅锌矿石一般都要经过选矿富集成精矿才能冶炼铅、锌金属产品。矿石技术加工选冶试验，是地质勘探工作的重要组成部分，是评价矿床能否作商品矿石开发的重要依据之一，因此在地质勘探过程中必须进行矿石可选性试验。在详查或初勘阶段，一般应做实验室初步可选性试验，在初勘或详勘阶段一般要做详细可选性试验。当矿石物质成分复杂，又有巨大综合利用价值的大中型、超大型矿床或属新类型矿石，除进行详细可选性试验外，必要时还要做实验室规模的扩大试验。对某些矿石类型当用选矿方法得不到合格精矿产品或无法单体分离时，还要进行实验室冶炼试验。 在进行矿石可选性试验之前，首先应进行矿床矿石物质成分研究，划分矿石类型，查明元素赋存状态，鉴定矿物种类、矿石结构构造、嵌布粒度特性，为选矿试验制定合理工艺流程提供依据。铅锌矿石工业类型划分，是在矿石自然类型基础上，按矿石氧化程度不同硫化石(铅或锌氧化率10%)、氧化矿石(铅或锌氧化率30%)、混合矿石(铅或锌氧化率10%30%)。按矿石中有用组分不同，可分为铅矿石、锌矿石、铅锌矿石、铅锌铜矿石、铅锌硫矿石、铅锌铜硫矿石、铅锡矿石、铅锑矿石、锌铜矿石等。按矿石结构构造不同，可分为浸染状矿石、致密块状矿石、角砾状矿石、条带状矿石、细脉浸染状矿石等。当选冶部门需要按矿石类型、分采、分选(冶)时，而在地质剖面图上能够圈出，且与相邻剖面能对应相连，则应圈出其分布范围，分别计算储量。 铅锌矿的选矿试验，根据矿石类型不同，则选择不同的选矿方法。硫化矿石通常用浮选方法。氧化矿石用浮选或重选与浮选联合选矿，或硫化焙烧后浮选，或重选后用硫酸处理再浮选。对于含多金属的铅锌矿石，一般用磁浮、重浮、重磁浮等联合选矿方法。 铅锌矿冶炼方法：硫化铅精矿是炼铅的主要矿物原料，其冶炼方法有火法和湿法两种。目前以火法为主，湿法处于试验研究阶段。火法炼铅采用烧结焙烧-鼓风炉熔炼和反应熔炼、沉淀熔炼等方法。铅的精炼主要采用火法精炼，其次是电解精炼。 硫化锌精矿是炼锌的主要矿物原料，也有火法和湿法冶炼。火法冶炼采用竖罐蒸馏、平罐蒸馏或电炉；湿法炼锌，近20年来发展很快，已成为炼锌的主要方法。火法炼锌所得粗锌采用蒸馏法精炼或直接应用；而湿法炼锌所得电解锌，质量较高，无需精
