浅谈当前全球矿产勘查态势 总被引:1,自引:1,他引:0
近几年来国际石油、煤炭、铁和铜等主要矿产价格暴跌,全球大宗商品需求增加明显放缓,全球矿产勘查投入也连续大幅下跌。为全面准确把握近期全球矿产勘查基本态势,本论文以SNL金属与矿业集团(SNL MetalsMining)最新发布的第25版公司勘查战略报告为数据基础,对全球矿产投入的金额、地区、矿种、投入主体及勘查阶段等多个方面进行了详细的解读和剖析,总结了全球矿产勘查的态势,推断近期内矿业形势将持续低迷,大宗商品的超级周期或已结束,矿业投资趋于理性化。并且据此提出了两方面的对策和建议,一是合理加快我国矿业"走出去"的步伐,二是加强对国内勘查布局进行合理化调整。 相似文献

2018年全球经济增长乏力,全球矿业市场转向下行,投资者对矿业市场的信心下降,矿产品价格接连下跌。中国经济和矿业市场总体平稳运行,油气地质勘查和社会投资有所回升,采矿业固定资产投资增加,采矿业利润持续增长,矿产品生产持续回暖,大宗矿产品进口持续增加。未来中国经济将会持续稳定发展,对矿产品需求将保持一定增速,对外政策将更加开放,矿产品贸易将进一步增加。受全球贸易紧张局势、地缘政治、政策不确定性因素影响,全球经济增长下行压力加大,海外矿业市场博弈激烈,但同时也是矿业企业走出去的机遇期。 相似文献

2014年,全球矿业受全球经济结构性调整、地缘政治格局变化等因素的影响,整体表现欠佳,基本延续了过去三年以来的发展颓势,突出表现为矿业指数中高位底部调整、大多数矿产品价格持续下降、矿业融资困难等。展望2015年,随着全球经济复苏多层化、复杂化,全球矿业将难以好转,在美元走强及新兴经济体增速下挫的重压之下,国际大宗矿产品价格难觅回升动力,全球矿业格局将继续深度调整。目前,全球矿业仍处于深度调整阶段,但表现出“四期叠加”特征,即矿业复苏酝酿期、技术创新孕育期、矿业管理政策调整博弈期和能源资源治理结构的改革期。对此,本文提出以下建议:一是稳定公益性地质调查投入;二是加强地质科技创新和勘查技术的研发投入;三是抓住机遇推进矿政管理改革;四是积极参与全球能源治理;五是加快实施矿产勘查“走出去”行动。 相似文献

正1.Status of rare earth polishing powder Rare earth polishing powder with high content of cerium oxide began to replace iron oxide for glass polishing and became one of the key materials in glass polishing process since 1940.Compared with traditional iron oxide,rare earth polishing powder has many advantages,such as fast polishing rate,high polishing quality and long service life.It can achieve good surface quality and improve operation conditions.For example,in lens polishing,the polishing work that cerium 相似文献

正Pyrometallurgy Laboratory of Baotou Research Institute of Rare Earths had independently developed a new preparation technology of rare earth alloy for NdFeB.The alloy can remarkably enhance the coercivity of NdFeB magnet but also evidently reduce the production cost of the magnet.The new master alloy was prepared in the kA pilot-scale electrolytic cell by the independent technology.The rare earth master alloy can be used as the raw material for NdFeB.Compared 相似文献

高效节能矿用防爆对旋主要通风机的叶片是主要通风机运行的关键部件,叶片在运行时不断受到气流的作用力,从而使叶片产生振动,当叶片振动的频率与叶片的固有频率接近时,容易产生共振从而导致叶片的断裂。一旦叶片断裂时,对主要通风机的安全运行产生致命的影响,从而导致矿山、化工等企业发生重大事故,将会产生不可估量的损失。基于有限元分析软件ANSYS,对高效节能矿用防爆轴流对旋主要通风机叶片进行模态分析及产生对应的六阶模态频率,对主要通风机叶片的运行频率、固有频率及产生的共振问题进行了原理分析,并且解决了叶片频率共振的问题,从而为主要通风机叶片结构设计提供理论依据,并对主要通风机叶片的安全运行提供保障。 相似文献
