Recent advancements in the applications of heavy minerals by modern science, engineering, technological and metallurgical industries especially in the demand by nuclear and power industries have significantly increased over the decades. This is the reason for the criticality and commerciality of products of heavy minerals and also necessitated their high demand by industries. The recovery of heavy minerals, such as: Zr and Ti associated minerals from their deposits is dependent on extractive metallurgy of transition and refractory metals from complex minerals. Based on the effectiveness and efficiency of mineral concentration as well as metal extraction, several challenges have been encountered in their recovery process, especially in their separation from associated mineral impurities or gangue. This review is however focused on investigating magnetic and electrostatic physical processing techniques and their applications in the beneficiation and recovery of heavy minerals. This will therefore, serve as a tool in reducing process steps and extraction complexity involved in downstream measures of dissolution and hydrometallurgical processes of the minerals.
近几十年来,现代科学、工程、技术和冶金行业在重矿物应用方面取得的进展显著增加,特别是核工业和电力行业的需求。这就是重矿物产品具有关键性和商业性的原因,也使得各行业对其有很高的需求。从重矿物矿床中回收锆和钛等伴生矿物,取决于从复杂矿物中提取过渡金属和难熔金属的冶金方法。基于矿物富集以及金属提取的有效性和效率,在其回收过程中遇到了一些挑战,特别是在将它们与伴生矿物杂质或脉石分离方面。然而,本综述着重研究磁选和静电物理处理技术及其在重矿物选矿和回收中的应用。因此,这将成为减少矿物溶解和湿法冶金下游措施中涉及的工艺步骤和提取复杂性的一种手段。
