【摘要】：白銀公司是集采、選、冶為一體的綜合性大型企業(yè)，銅冶煉系統(tǒng)自生產(chǎn)以來(lái)，爐渣作為一種工業(yè)廢物，一直未被開(kāi)發(fā)利用。2011年白銀公司已在銅冶煉渣場(chǎng)堆積近800萬(wàn)噸的冶煉廢渣，其中的重金屬污染物含量較高，如果不能盡快開(kāi)發(fā)利用而繼續(xù)堆存，不但占用大量的土地，而且每年還需支付高昂的渣場(chǎng)維護(hù)費(fèi)用，更為嚴(yán)重的是這些重金屬將污染土壤、水體甚至大氣，嚴(yán)重惡化周邊的環(huán)境質(zhì)量。 本文根據(jù)國(guó)內(nèi)外冶煉渣選礦的成功生產(chǎn)經(jīng)驗(yàn)，利用銅冶煉廢渣回收銅精礦，，同時(shí)綜合回收尾渣作為水泥行業(yè)生產(chǎn)的原料，研究結(jié)果得到應(yīng)用后可以在一定程度上減輕銅冶煉廠對(duì)外購(gòu)市場(chǎng)的依賴程度，增強(qiáng)企業(yè)的抗風(fēng)險(xiǎn)能力，提高產(chǎn)品的市場(chǎng)競(jìng)爭(zhēng)力。 通過(guò)對(duì)冶煉廢渣進(jìn)行再生利用，將污染源轉(zhuǎn)化為再生資源，變廢為寶，化害為利，同時(shí)設(shè)計(jì)中充分考慮利用現(xiàn)有生產(chǎn)設(shè)備、設(shè)施，做到低投入、高產(chǎn)出、低能耗、無(wú)污染、回水循環(huán)利用率高，采用先進(jìn)的工藝、技術(shù)和設(shè)備處理銅冶煉廢渣，產(chǎn)出的銅精礦作為銅冶煉生產(chǎn)的優(yōu)質(zhì)原料，同時(shí)篩選后的尾礦可作為水泥等行業(yè)生產(chǎn)的原料，實(shí)現(xiàn)尾礦“零排放”，本文所設(shè)計(jì)的方案對(duì)尾礦資源全部回收，同時(shí)對(duì)廢水進(jìn)行循環(huán)利用，因此基本無(wú)廢水和固體污染物排放。充分體現(xiàn)了“減量化、再利用、資源化”節(jié)約綜合利用原則，不僅有利于環(huán)境保護(hù)和安全生產(chǎn)，有利于公司的可持續(xù)發(fā)展，同時(shí)還可為企業(yè)帶來(lái)可觀的經(jīng)濟(jì)效益。 本文研究?jī)?nèi)容契合了國(guó)家建設(shè)節(jié)約性、環(huán)境友好型社會(huì)的總體要求，是解決影響社會(huì)經(jīng)濟(jì)發(fā)展特別是從根本上消除嚴(yán)重危害人民群眾健康的環(huán)境污染問(wèn)題的舉措。實(shí)現(xiàn)廢渣的再利用，使資源綜合利用率達(dá)到極限，將對(duì)整個(gè)有色行業(yè)提高資源綜合利用水平能產(chǎn)生積極意義，對(duì)其它金屬冶煉渣的處理提供借鑒。
[Abstract]:Baiyin Company is a comprehensive large enterprise which integrates mining, selecting and smelting. Since copper smelting system was produced, slag has been used as a kind of industrial waste. It has not been exploited and utilized. In 2011, Silver Company has accumulated nearly 8 million tons of smelting waste residue in copper smelting slag yard, among which heavy metal pollutants are relatively high. If it cannot be developed and utilized as soon as possible and continues to store, it will not only occupy a large amount of land, Moreover, the maintenance cost of slag yard is also high every year. What is more, these heavy metals will pollute soil, water body and even atmosphere, and worsen the surrounding environmental quality seriously. Based on the successful production experience of smelting slag at home and abroad, copper concentrate is recovered from copper smelting waste slag and tailings are reclaimed as raw materials of cement industry. The application of the research results can reduce the dependence of copper smelters on the outsourcing market to a certain extent, enhance the enterprises' ability to resist risks and improve the market competitiveness of the products. Through the recycling of smelting waste residue, the source of pollution is transformed into renewable resources, and the waste is transformed into a treasure, and the damage is turned into profit. At the same time, the existing production equipment and facilities are fully considered in the design, so as to achieve low input, high output, low energy consumption and no pollution. The recycling efficiency of backwater is high, the advanced technology, technology and equipment are used to treat the waste residue of copper smelting, the produced copper concentrate is used as the high quality raw material for copper smelting, and the filtered tailings can be used as raw materials for cement and other industries. In order to realize "zero discharge" of tailings, the scheme designed in this paper can recover all the tailings resources and recycle the waste water at the same time, so there is basically no discharge of waste water and solid pollutants. It fully embodies the principle of "reducing, reusing and utilizing resources", which is not only conducive to environmental protection and production safety, but also conducive to the sustainable development of the company, and can also bring considerable economic benefits to enterprises. The research content of this paper accords with the overall requirements of the national construction of economizing and environment-friendly society, and is a measure to solve the problem of environmental pollution which affects the development of society and economy, especially the serious harm to the health of the people. To realize the reuse of waste slag and to reach the limit of comprehensive utilization ratio of resources will produce positive significance for the whole nonferrous industry to raise the level of comprehensive utilization of resources and provide reference for the treatment of other metal smelting slag.
