【摘要】：矿产资源高强度开发带来了尾矿的大量排放。目前,国内尾矿堆存量已超过百亿t。尾矿中含有许多有用组分,特别是早年开采回收的水平低,大量有用组分被视为废物进入了尾矿库。随着经济社会快速发展,采选技术进步和矿产品价格高位运行使尾矿规模化利用成为可能。当前,尾矿规模化利用的关键点集中体现在经济性,需要加强经济分析,为企业开发利用尾矿资源提供参考。为此,通过构建尾矿规模化利用的经济分析模型,验算了国家首批示范基地铜陵有色集团公司尾矿综合利用项目因价格变动,生产由盈利转为亏损的实际情况;得出了当前矿产品价格是影响尾矿规模化利用的决定因素这一结论,建议国家应继续加大对尾矿综合利用的税收和财政政策支持,帮助企业渡过难关,实现尾矿利用的资源效益、经济效益、环境效益和社会效益的有效统一。
[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.
