摘要:
全球银矿资源以共伴生银为主,分布极不均衡,其中秘鲁、澳大利亚、波兰、智利、中国、墨西哥6国白银储量占全球总探明白银储量的80%以上.随着全球银矿资源的开发利用,全球银矿资源呈现出开采品位降低,入选矿石质量变差,整体产出率降低的趋势.受多种因素影响,预计全球白银整体产量将不再增长甚至出现下滑趋势,长期来看全球白银的供应将会趋紧.全面介绍了全球银矿的资源和应用现状,分析了银资源的供需状况、价格等因素的变化趋势,为我国银矿业的投资、开发、管理提供参考依据.
Abstract:
The global silver resources mainly were paragenetic and associated minerals , of which the distribution is uneven .About 80%of global silver explored reserve comes from Peru , Austral-ia, Poland, Chile, China and Mexico .With development of the global silver resources , the grade of global crude silver ore decreased , the quality of processed ore become poor , and the whole yield declines.Influenced by many factors , it is predicted that global silver capacity will not grow or e-ven declined , and the supply of sliver resource become tighter and tighter .The status of resources and utilization of global silver was introduced comprehensively in this paper .The tendency of sup-ply and demand as well as factors such as price were also analyzed .This study provided reasonable references for investment , exploitation and management of national silver resources .
