氧化矿石,特别是产自伟晶岩的氧化矿石,常常含有许多稀有矿物,如黄玉矿、绿柱石、磷灰石、萤石、钶铁矿和含有铯,锆、铀、钽及其它许多稀土族元素的稀有矿物。莱克菲尔德研究有限公司为了用浮选方法回收这些矿物,已进行了大量的研究工作,目的是使矿物产品的纯度能达到直接销售的标准,或者可作为水冶处理的供料。结果,在新药剂和工艺流程方面,已取得了若干专利。本文介绍了铌、锆、铍和稀土氧化物选矿流程的研究结果。为了适应含有不同矿物的各种矿石的浮选需要,对各种矿物的可浮性进行了研究。研究中得到了影响浮选效果的重要参数;试验了如何有效配合使用各种抑制剂;开发了经过改进的新的脂肪酸。文中介绍了回收高品位稀土精矿、锆精矿和烧绿石精矿的流程。 Oxidized ores, especially those produced from pegmatite, often contain many rare minerals such as topaz, beryl, apatite, fluorite, and iron ores as well as metals containing cesium, zirconium, uranium, tantalum and many other rare earths Rare minerals of the ethnic group. In order to recover these minerals by flotation, Lakefield Research Limited has done a great deal of research in order to make the purity of mineral products meet the criteria of direct sale or as a feedstock for water treatment. As a result, several patents have been obtained on new pharmaceuticals and processes. This article describes the results of the beneficiation process for niobium, zirconium, beryllium and rare earth oxides. In order to meet the flotation needs of various ores containing different minerals, the floatability of various minerals has been studied. Important parameters influencing flotation were obtained in the study; how to effectively use various inhibitors; how to develop new and improved fatty acids. This paper describes the recovery of high grade rare earth concentrate, zirconium concentrate and pyrochlore concentrate process.
