Flotation of a Beryllianite-type Uranium-Beryllium Co-associated Ore in Xinjiang
摘要
Abstract
Address to the issue of high fluorine content in the flotation concentrate of a super-large Beryllianite-type uranium-beryllium co-associated ore in Xinjiang,the mineral and elemental composition,as well as the mineral dissemination characteristics were studied.Flotation process of"floating fluorite first and then beryllium"was adopted for flotation.Grinding fineness and flotation reagent system were optimized through systematic flotation condition tests.The results show that for the raw ore with a beryllium grade of 0.435％and a grinding finness of-325 mesh accounting for 93％,under the conditions of 1.5 kg/t for sodium silicate in roughing,2 kg/t for NaOH,700 g/t for oxidized paraffin soap in roughing,and 500 g/t for swept oxidized paraffin soap in scavenging,The technical indicators of flotation with beryllium grade of 3.36％and recovery rate of 81.99％are obtained.The process can achieve effective enrichment of beryllium minerals.关键词
