Abstract
Based on related fundamental data,this paper analyzed the characteristics of nonferrous metal mineral resources of Sichuan province ;Combining to the reality of the nonferrous metals industry in Sichuan and the actuality of the nonferrous metals industry in China,the paper put forward some countermeasures about sustainable utilization of nonferrous metals mineral resources in Sichuan.It is pointed out that nonferrous metals mineral resources of Sichuan have the following main characteristics: Firstly,they almost comprise all kinds of nonferrous metals;Secondly,their reserves are comparatively abundance;Thirdly,their grades are both fine and inferior;Fourthly,the space distribution of their deposits is relatively centralized;Fifthly,their deposits are few large scale ones and many small scale ones,and the average scale of their deposits is relatively small;Sixthly,their tenors are both rich and poor,and their deposits are little rich ones and many poor ones;Seventhly,associate and commensal useful components are abundant in them.It is put forward that countermeasures,which are about sustainable utilization of nonferrous metals mineral resources in Sichuan,are following: Firstly,economizing resources,laying equal stress on the resources exploiture and the resources protection;Secondly,bringing forth new ideas in science and technology,activating bad resources;Thirdly,comprehensively and circularly utilizing resources,raising the extraction ratio of mineral resources;Fourthly,putting geologic examination in advance,searching nonferrous metals mineral resources which are lack and high grade or in deep and periphery of old mines;Fifthly,paying equal attention to the resources exploiture and the entironment protection,developing the green mineral industry;Sixthly,adjusting taxes and fees,lightening the mine enterprise burden,strengthening the mine enterprise functions for ore prospecting and environments constucting,and so on.
