【摘要】：礦產(chǎn)資源高強(qiáng)度開發(fā)帶來了尾礦的大量排放。目前,國(guó)內(nèi)尾礦堆存量已超過百億t。尾礦中含有許多有用組分,特別是早年開采回收的水平低,大量有用組分被視為廢物進(jìn)入了尾礦庫(kù)。隨著經(jīng)濟(jì)社會(huì)快速發(fā)展,采選技術(shù)進(jìn)步和礦產(chǎn)品價(jià)格高位運(yùn)行使尾礦規(guī)模化利用成為可能。當(dāng)前,尾礦規(guī)�；玫年P(guān)鍵點(diǎn)集中體現(xiàn)在經(jīng)濟(jì)性,需要加強(qiáng)經(jīng)濟(jì)分析,為企業(yè)開發(fā)利用尾礦資源提供參考。為此,通過構(gòu)建尾礦規(guī)模化利用的經(jīng)濟(jì)分析模型,驗(yàn)算了國(guó)家首批示范基地銅陵有色集團(tuán)公司尾礦綜合利用項(xiàng)目因價(jià)格變動(dòng),生產(chǎn)由盈利轉(zhuǎn)為虧損的實(shí)際情況;得出了當(dāng)前礦產(chǎn)品價(jià)格是影響尾礦規(guī)�；玫臎Q定因素這一結(jié)論,建議國(guó)家應(yīng)繼續(xù)加大對(duì)尾礦綜合利用的稅收和財(cái)政政策支持,幫助企業(yè)渡過難關(guān),實(shí)現(xiàn)尾礦利用的資源效益、經(jīng)濟(jì)效益、環(huán)境效益和社會(huì)效益的有效統(tǒng)一。
[Abstract]:High intensity exploitation of mineral resources brings a large amount of tailings discharge.At present, the domestic tailings heap stock has exceeded ten billion tons.There are many useful components in tailings especially in the early years the level of recovery is low and a large number of useful components are considered as waste into the tailings reservoir.With the rapid development of economy and society, the development of mining and dressing technology and the high price of mineral products make the utilization of tailings on a large scale possible.At present, the key point of large-scale utilization of tailings is economy, which needs to strengthen economic analysis and provide reference for enterprises to develop and utilize tailings resources.Therefore, by constructing the economic analysis model of the large-scale utilization of tailings, the actual situation that the comprehensive utilization project of tailings of Tongling Nonferrous Group Company, the first demonstration base of the country, is changed from profit to loss due to price change is calculated.This paper draws the conclusion that the price of mineral products is the decisive factor affecting the large-scale utilization of tailings. It is suggested that the state should continue to increase the tax and financial policy support for comprehensive utilization of tailings to help enterprises tide over the difficulties.To realize the effective unification of resource benefit, economic benefit, environmental benefit and social benefit of tailings utilization.
