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.

9819852Miller 作为 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成果，Jan Miller 教授和南非波切夫斯特鲁姆大学的 John Davidtz 教授启动了一项合作研究计划。 波切夫斯特鲁姆大学的研究人员已经完成了大量的应用研究，其中涉及用于战略矿物浮选分离的新试剂的研究，包括含有铂族金属的矿物。 这项应用研究已经得到南非研究发展基金会 (FRD) 的支持。 另一方面，基础研究还很缺乏。 在这方面，计划与犹他大学合作研究项目，以建立与这些新试剂相关的基础浮选化学。 犹他大学的研究小组在浮选化学方面拥有丰富的经验，作为该项目的一部分，南非学生 Ronel du Plessis 女士已经开始研究生学习。 除了基础研究外，还将对美国工业的矿石样品进行检查以评估新试剂，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矿产行业新技术的开发，以回收对两国具有战略重要性的铂、铜和其他金属。
