摘要:
磷矿是重要的工农业生产不可缺少的矿产资源,我国磷矿资源储量位居世界第二,但是我国磷矿资源难采选矿多、高品位矿少.随着磷矿资源的不断开采,我国磷富矿将耗尽,品位变低,磷矿固体废弃物的产生量将变多,越来越多的磷矿固体废弃物的产生不仅严重危害了环境,而且造成了极大的资源浪费,严重制约了磷矿行业的发展.合理利用磷矿国体废弃物,可以兼顾并综合体现“开源节流”的双重效益,化害为利、变废为宝.通过调查和比较,总结了磷矿固体废弃物利用过程中的主要问题.为进一步资源化利用磷矿固体废弃物,建议加强磷矿固体废弃物资源化利用技术研究,并重视一系列经济政策的落实.
Abstract:
Phosphate is kind of mineral resource which is indispensable to industrial and agricultural production.Our country has the second largest reserve of phosphate in the world.However,a large proportion of the phosphate ores are low grade and they are difficult for beneficiation.With the continuous mining of phosphate rock,high grade phosphate ores will run out.The grade of phosphate rocks will be getting lower and lower as well the phosphate solid waste will become more and more.A large amount of phosphate solid waste not only causes serious damage to the environment,but causes huge waste of resources.Furthermore,it restricts the development of phosphate industry seriously.The utilization of solid waste can take into account and embody the double benefits of" increasing income and reducing expenditure",which could turn ecological burden into resource wealth.Through investigation and comparison,the main problems in the process of phosphate solid waste utilization have been summarized.In order to use of phosphate solid waste further,we suggest that we should attach great importance to the technology research on resource utilization of phosphate solid waste and the implementation of a series of economic policies.
