0352807 Miller This award funds a collaborative research program between the flotation chemistry research groups at the University of Utah, USA, and Pretoria University in South Africa to study advanced flotation chemistry technology for the improved recovery of strategic mineral resources containing platinum group metals (PGMs). Existing flotation chemistry for increased recovery of PGM sulfide minerals from current deposits can be improved for most operations. More importantly, however, the efficient recovery and utilization of new PGM mineral resources (the Platreef deposit of South Africa and the Great Dyke deposit of Zimbabwe) will require quite significant improvements in flotation chemistry. For example, the new strategic PGM resources are significantly different from current PGM resources, being complex arsenides and tellurides that are now lost using current processing chemistry. Three major flotation chemistry research problems associated with the processing of PGM mineral resources will be addressed: flotation of PGM arsenide and telluride minerals, control of pyrrhotite flotation, and depression of talc gangue minerals. This research program is designed to establish surface chemistry and/or electrochemistry conditions which will provide a fundamental basis to solve these problems and improve the efficiency of the PGM flotation separation. This proposed collaborative research program has broad potential impact. The need for such surface chemistry research is significant in view of the importance of PGM production to both the U.S. and South Africa. The efficient recovery of PGMs is also of critical importance to the global community because of increased demand for PGMs, for example, because of their use in catalytic converters to reduce pollution from automotive exhaust. The project is expected to extend collaboration beyond the initial partners, Pretoria University and PGM companies in South Africa such as Impala Platinum. Not only will this research provide much needed new technology for the PGM industries, but it also affords the opportunity for students and researchers from both the U.S. and Africa (South Africa, Botswana, and Zimbabwe) to build professional and personal collaborations that can expand scientific, social and cultural understanding. Finally, the proposed research has been organized to include the exchange of graduate students with opportunity for students from Pretoria University to use advanced instrumentation at the University of Utah while students from the University of Utah will travel to South Africa for evaluation of new flotation chemistry technology at plant sites.

0352807 Miller 该奖项资助美国犹他大学和南非比勒陀利亚大学浮选化学研究小组之间的合作研究项目，研究先进的浮选化学技术，以提高含铂族金属 (PGM) 的战略矿产资源的回收率。对于大多数作业来说，现有的浮选化学方法可以提高从现有矿床中回收铂族金属硫化物矿物的效率。然而，更重要的是，新铂族金属矿产资源（南非的 Platreef 矿床和津巴布韦的 Great Dyke 矿床）的有效回收和利用将需要对浮选化学进行相当大的改进。例如，新的战略铂族金属资源与当前的铂族金属资源显着不同，它们是复杂的砷化物和碲化物，而使用当前的加工化学物质现在会损失这些资源。将解决与PGM矿物资源加工相关的三个主要浮选化学研究问题：PGM砷化物和碲化物矿物的浮选、磁黄铁矿浮选的控制以及滑石脉石矿物的抑制。 本研究项目旨在建立表面化学和/或电化学条件，为解决这些问题和提高PGM浮选分离效率提供基础基础。这项拟议的合作研究计划具有广泛的潜在影响。鉴于铂族金属生产对美国和南非的重要性，对此类表面化学研究的需求非常重要。铂族金属的有效回收对于国际社会也至关重要，因为铂族金属的需求不断增加，例如，因为铂族金属在催化转化器中的使用可减少汽车尾气污染。该项目预计将扩大合作范围，超越最初的合作伙伴比勒陀利亚大学和南非的 PGM 公司（例如 Impala Platinum）。这项研究不仅将为铂族金属行业提供急需的新技术，而且还为来自美国和非洲（南非、博茨瓦纳和津巴布韦）的学生和研究人员提供建立专业和个人合作的机会，从而扩大科学领域的影响。 、社会和文化理解。最后，拟议的研究计划包括研究生交流，比勒陀利亚大学的学生有机会在犹他大学使用先进仪器，而犹他大学的学生将前往南非评估新的浮选化学技术在工厂现场。
