Qinghai News Network News to Xitieshan Lead-Zinc Mine, just as they came to the Qaidam a circular economy industrial chain, lead-zinc resources from here to keep the Gan River Industrial Park and Da Qaidam businesses in the region extending downstream industries such as form a non-ferrous metal resources, integrated development and recycling.

xitiesan Western Mining Co., Ltd.-owned lead-zinc is a large comprehensive mining enterprises, mines since 1986, put into production, product quality has gradually increased and the current annual mining capacity of 1.5 million tons of ore, has grown into the largest in Qinghai Province The non-ferrous metals mining and joint ventures across the country large-scale mining and smelting of joint ventures. Company products are mainly for the lead concentrate, zinc concentrate and tailings sulfur concentrate. Previously, business-to-adopt, after dressing the direct export of primary products, tailings, waste, value-added products is not high, resources are not fully utilized. At the same time, environmental pollution problem is becoming increasingly apparent. In recent years, companies follow the circular economy reduction, reuse and recycling principles, changes in the extensive type, predatory mine production methods, through the introduction of projects and new product development, allows businesses to extend the industrial chain, and reducing consumption of resources and environmental pollution, to achieve the depth of comprehensive utilization of mineral resources.

industrial park in the Gan River west of lead mining industry branch, there are two annual production capacity is 5 million tons of crude lead production lines and electrical lead lines, xitiesan lead-zinc concentrates produced some lead here, deep processing Crude lead and power lead. Lead the production of the crude produced in the course of sulfur dioxide, sulfur trioxide gas and other previously discharged directly into the air, causing a certain degree of environmental pollution. Last year, companies invest 2.5 billion yuan, from Sweden to introduce advanced production technologies, recycling of waste for the production of this part of the sulfur-containing sulfuric acid. Another waste — Slag also provided to the park’s Huangshui Cement Co., Ltd., for the production of high-grade cement. In the production of electrolytic lead, lead slag also recyclable, for refining gold, silver and other precious metals. Extension of industrial chain a step by step to make our products continuously improve the value added, while harmful to the environment is also greatly reduced.

xitiesan production of zinc concentrates in the lead-zinc, also contain gold, silver, indium, cadmium and other valuable metals, particularly metal indium and other rare metals. Western Mining Corporation after full argument, consultation and testing, the current industrial park around the Gan River zinc smelting production system, has established a comprehensive, well rare, rare metals recycling production industrial system. In this system, material recycling, metals indium, cadmium, gold, silver, etc. have been effectively recovered, and no waste water and solid waste emissions, only after proper treatment, for sale to low-iron slag cement raw materials to do .

the project runs successfully, you can add an annual industrial output value of 200 million yuan more than 50 million yuan to increase revenue, reduce solid waste emissions by two thousand tons, more than 5,000 cubic meters of liquid waste emissions, and can bring a number of related industries in the vicinity.

do a good job re-use of mine tailings is an important part of mining circular economy. In the past, when the XITIESHAN lead-zinc ore-dressing, resulting in the sulfur content in the tailings as waste disposal, to that end, businesses in 1993, 100 invested yuan to build a tailings pond for the stockpiling of tailings a year to in the maintenance, operating costs will need 290,000 yuan. In recent years, enterprises turning waste into treasure, their deep-processing as a sulfur concentrate, in turn sulfur concentrate provided to the upstream and downstream enterprises in Qinghai innovative mining company’s sulfuric acid plant production of sulfuric acid, sulfuric acid product further upstream and downstream enterprises — Dachaidan of boric acid plant and so is constantly spreading. Such a cycle, re-use, comprehensive utilization of resources have been every year for the enterprise can save 2.25 million sewage charges, the negative impact on the environment down to a minimum. Upstream and downstream enterprises to reduce costs due to costs, transportation fees to increase economic efficiency.

In addition, the division of water XITIESHAN 40 km away from the small Qaidam Lake, the company has invested three million yuan construction of waste water recovery unit, about 1,400 tons per day waste water recycling, water saving each year about 50 million tons, saving funding of about 320,000 yuan. Recycling of water resources not only saves the cost of production, reducing environmental pollution, but also ease the tense situation in the local water resources to achieve the economic and environmental “win-win.”

As a result, xitiesan lead-zinc mine of resources to achieve the efficient use of materials, closed-loop, to extend the industrial chain, and low pollutant emission, “zero discharge” to achieve the economic, environmental and social benefits of the unity. (Xinhua / Xue Jun)

锡铁山的循环经济发展“将在年底矿山资源利用率”

青海新闻网络新闻的锡铁山铅锌矿，正如他们来到从这里柴达木循环经济产业链，铅，锌资源，以保持在扩大，如表下游产业区域淦工业园和大柴企业非有色金属资源综合开发和回收。

锡铁山西部矿业有限公司拥有的铅，锌的大型综合性矿山企业，矿山自1986年投产以来，产品质量逐年提高，目前150万吨矿石年开采能力，已经成为在青海省{zd0}的有色金属开采和全国大规模开采和冶炼合资企业的合资企业。公司产品主要为铅精矿，锌精矿和尾矿硫精矿。以前，企业对采用，穿上衣服，初级产品，尾矿，废弃物，价值直接出口产品附加值不高，资源没有得到充分利用。与此同时，环境污染问题日益明显。近年来，公司按照循环经济的减少，再用和循环再造的原则，在粗放型的变化，掠夺性的开采量的方法，通过项目的引进和新产品开发，允许企业延长产业链，减少资源消耗和环境污染，实现矿产资源综合利用的深度。

在淦铅矿业分公司西工业园，有两个年生产能力为5万吨原油铅生产线和电力线吨铅，锡铁山铅锌矿铅精矿产生了一些在这里，深加工粗铅和权力领导。铅生产中的二氧化硫，三氧化硫气体和其他课程以前排入空气中直接生产的原油，造成了一定程度的环境污染。去年，公司投资2.5亿元人民币，从瑞典引进先进的生产技术，废物循环再用的这一部分生产硫含硫酸。另一种浪费—渣还为xx水泥生产园区的湟水水泥有限公司。在生产电解铅，铅渣还回收，精炼黄金，白银和其他贵重金属。产业链延伸一步一步，使我们的产品，不断提高附加值，同时有害于环境也大大减少。

锌锡铁山生产集中在铅，锌，还含有金，银，铟，镉等贵重金属，特别是金属铟及其他稀有金属。西部矿业公司经过充分的论据，咨询和测试，目前围绕淦锌冶炼生产系统的工业园区，建立了全面，稀有，贵金属回收生产的工业体系。在这个系统中，物料回收，金属铟，镉，金，银等得到有效恢复，没有废水和固体废物排放量只有在适当的xx，出售的低铁矿渣水泥的原料做的。

项目的成功运行，您可以添加2.00亿元以上5000.0万元，年工业产值增加收入，减少2万吨，超过5000液体废弃物排放立方米固体废物排放量，并能带来人数在附近相关行业。

做好重新尾矿利用是矿业循环经济的重要组成部分。在过去，当锡铁山铅锌矿选矿，在作为废物处理的尾矿硫含量造成，为此，在1993年的企业，投资100万元修建的尾矿储存一年的尾矿池1在维护，运营成本将需要29.0万元。近年来，企业变成废为宝，他们深为硫精矿加工，硫精矿，从而提供给青海创新矿业公司的硫酸，硫酸厂生产的上游和下游企业，硫酸产品进一步上行和下行企业—柴旦硼酸厂等正在不断蔓延。这样的循环，再利用，资源综合利用已为企业每年可节省225.0万排污费，对环境降低到{zd1}限度的负面影响。上游和下游企业降低成本，由于成本，运输费用，提高经济效益。

此外，水锡铁山40公里的小柴达木湖师以外，该公司已投资300万废水回收装置，每天约1400吨，废水循环利用，每年节水5000万吨左右人民币的建设，节省经费约32.00万元。水资源再利用，不仅节约了生产成本，减少环境污染，而且还缓解了当地水资源的紧张局势，实现经济和环境“双赢”。

结果，锡铁山铅锌矿矿山资源，以达到有效利用材料，闭环，延长产业链，和低污染物排放，“零排放”，以实现经济，环境和社会效益团结。 （记者/薛琚嗯）06.2.14
