金属矿产生产流程中的资源利用分析(英文)

A resource-oriented analysis of metallic ran material flows

不可再生资源利用是当今和将来社会发展最重要的基础之一。在经济发展中,我们应该对这些资源持以节约和限制消耗的态度。从1997年开始,德国科研协会525合作研究中心在此领域进行了研究,其研究内容是社会上感兴趣的、有关金属矿产并且涉及到的经济、生态和其他领域方面所争论的问题。本文以采矿废弃物处理子项目(子项目2)和环境子项目(子项目5)为例来介绍这些研究及其相关关系。以这些矿产的生产过程与储量平衡表分析为基础,按特征进行分类,并考虑它对环境的影响,对工业技术原因对公众健康的潜在影响进行数量分析。

The use of non-renewable resources is a fundamental basis of current and future societies. In the spirit of sustainable development we are committed to prudence with respect to the limitations of those reserves . The Collaborative Research Center 525, which is funded by the Deutsche Forschungsgemeinschaft since the beginning of 1997, aims to set up recommendations regarding the careful use of metallic raw materials in the conflicting area of interests of society such an economy, ecology and others. Scientists of different faculties co-operate, each representing a sub-project. The desired interaction between these projects will be presented in this paper at example of sub-project mining waste disposal (SP2) and sub-project environment (SP5 ) . We will take a closer look at the transportation of bauxite from a mine to an alumina refinery . The material flows which have been determined in the context of an inventory analysis are being classified and quantified with respect to their impact on environment and potential in view of technology and public welfare.
