US-South Africa Cooperative Research: The Surface Chemistry of New Collectors for the Flotation Recovery of Strategic MMaterials from Sulfide Mineral Resources

[9819852 .米勒]1997年6月在南非举行的美国-南非矿物和化学加工多相系统联合研讨会的结果是，南非Potchefstroom大学的Jan Miller教授和John Davidtz教授发起了一项合作研究计划。Potchefstroom大学的研究人员已经完成了大量的应用研究，其中包括研究用于浮选分离战略性矿物的新试剂，包括含有铂族金属的矿物。这项应用研究已经得到了南非研究发展基金会的支持。另一方面，缺乏基础研究。在这方面，计划与犹他大学开展合作研究项目，以建立与这些新试剂相关的基本浮选化学。犹他大学的研究小组在浮选化学方面有丰富的经验，作为项目的一部分，南非学生罗内尔·杜·普莱西斯女士已经开始了研究生学习。除了基础研究外，还将检查来自美国工业的矿石样品，以评估新试剂，这应该是支持南非工业发展的一项重要活动。这项研究工作的结果将有助于发展矿物工业的新技术，以回收对两国具有战略重要性的铂、铜和其他金属。

9819852MillerAs a result of a joint US-South Africa Workshop on Multiphase Systems in Mineral and Chemical Processing held in South Africa in June 1997, a cooperative research program has been initiated between Professor Jan Miller and Professor John Davidtz of Potchefstroom University in South Africa. Researchers at Potchefstroom University have completed a substantial amount of applied research, which has involved the study of new reagents for the flotation separation of strategic minerals, including minerals containing the platinum-group metals. Already this applied research is being supported by the Foundation for Research Development (FRD) in South Africa. On the other hand, fundamental studies are lacking. In this regard, a cooperative research program with the University of Utah is planned to establish the fundamental flotation chemistry associated with these new reagents. The research group at the University of Utah has extensive experience in flotation chemistry, and as a part of the program a South African student, Ms. Ronel du Plessis, has already started graduate studies. In addition to fundamental studies, ore samples from US industries will be examined to evaluate the new reagents, which should be an important activity to support South African industrial development. The results of this research work will be useful for the development of new technology in the minerals industries for the recovery of platinum, copper, and other metals of strategic importance to both countries.
