摘 要:矿产资源是全球经济发展长期的基础和重要支撑。矿产资源的耗竭性和环境保护的紧迫性决定了综合利用的重要性。"十二五"规划要求强化宏观指导,完善政策措施,提高资源综合利用水平。我国矿产资源综合利用的法规政策日趋完善,部分采选技术达到或接近世界先进水平,一些重点大中型矿区采区回采率超过80%,金属矿山露天开采回采率达85%以上。我国50%以上的钒,22%以上的黄金、50%以上的铂、钯、碲、镓、铟、锗来自于综合利用。通过激励约束机制,引导社会资金进入矿产资源综合利用领域,引进先进生产工艺和技术设备,强化监督管理与考核,实现资源综合利用长效机制。Mineral resources is a long term basis and an important support for the development of the global economy. The depletion of mineral resources and the urgency of environmental protection determine the importance of the comprehensive utilization. "Twelfth Five-Year Plan" require to strengthen macro guidance, perfect policy measures, improve the level of comprehensive utilization of resources. Regulations and policies of the comprehensive utilization of mineral resources in China is maturing, partial mining technology has reached to the advanced level of world,The mining recovery rate of some large and medium mining area was over 80% ,open mining recovery rate of metal mine reached 85 % or more. More than 50 of vanadium in China,more than 22 % of gold, more than 50 % of the platinum, palladium, tellurium, gallium, indium, germanium from comprehensive utilization. Through the incentive and restraint mechanisms, to guide the social capital into the mineral resources comprehensive utilization field, introduce the advanced production technology and technical equipment, strengthen supervision and management and evaluation, comprehensive utilization of resources to realize long-term mechanism.
