在贵金属选别方面,研究工作似乎大都集中于现有的选矿方法和工艺的改进上,这固然很重要,但是,在提高贵金属矿物回收率这一研究课题中,如果能取得更大的成果,将会更加令人兴奋。例如,澳大利亚选矿研究学会理事,老一辈冶金学专家Arnold F.Griffin认为:在金的回收方面,自埃及时代以来,选金的基本方法并没有多大改观,迄今,金矿房的工作仍然肮脏令人厌烦。除此而外,选金过程中,操作工人必然要与金子接触,因此,安全同题也至关重要。 Griffin还说,他们公司已经研究出一种在密封槽中回收高品位金的工艺(专利权正在申请中)。利用这种工艺方法选金,可以圆满地解决上述两方面的同题。他还对(世界采矿设备)杂志的编辑们谈到有关他参加最近在美国内华达里诺(Reno)举行的第一次国外贵金属会议的情况。这次会议是以座谈会的形式召开的,出席这样的讨论会、座谈会确实都很值得。大会介绍了学术论文以后,又展开了个人的学术思想交流、质疑和解答问题等项活动。出席由(世界采矿设备)杂志共同主持的这次讨论会的代表,登记人数超过200人。他们分别来自加拿大、加纳、美国、南非、美国、瑞典、新加坡、津巴布韦,巴西、秘鲁,澳大利亚,智利,联邦德国,玻利维亚,厄瓜多尔,墨西哥、比利时、尼加拉瓜、芬兰、新几内亚、荷兰,多米尼加共和国和圭亚那。下面刊登会上提交的几篇最重要的论文,其它的论文将陆续登载于本杂志即将出版的几期上。一篇题为(金矿石和精矿选别中的生物工艺学)的论文,已经发表在《生界采矿设备》1984年第七期上。
While it is important to focus research efforts on the selection of precious metals for the improvement of existing beneficiation methods and processes, it is important to study more precious metals in order to improve the recovery rate of precious metal minerals. However, It will be even more exciting. For example, Arnold F. Griffin, a member of the Australian Institute of Mineral Processing and the senior metallurgist, argues that since the egyptian era, the basic method for selecting gold has not changed much in the recovery of gold. To date, the work of the gold mine still remains dirty Dirty and annoying. In addition, during the election process, the workers must contact with gold. Therefore, the issue of safety is also of crucial importance. Griffin also said that their company has developed a process for the recovery of high-grade gold in sealed tanks (patent pending). The use of this process of gold election, you can satisfactorily solve the above two aspects of the same title. He also spoke to editors of World Mining Equipment about his recent attendance at the first foreign precious metal conference in Reno, Nevada, USA. The meeting was held in the form of a forum to attend such seminars, and the symposium was really worth it. After the conference introduced the academic papers, it started the activities of exchanging academic questions, questioning and answering questions. More than 200 delegates attended the symposium co-chaired by (World Mining Equipment) magazine. They are from Canada, Ghana, the United States, South Africa, the United States, Sweden, Singapore, Zimbabwe, Brazil, Peru, Australia, Chile, the Federal Republic of Germany, Bolivia, Ecuador, Mexico, Belgium, Nicaragua, Finland, New Guinea, the Netherlands, the Dominican Republic and Guyana. The following is a list of the most important papers submitted at the conference. Other papers will be published one after another in the forthcoming issue of this magazine. An essay entitled Biotechnology in Gold Ore and Concentrate Separation, has been published in Seismological Mining Equipment, Issue 7, 1984.
