Beneficiation Exploration Test of a Low-grade Rubidium Ore
A low-grade rubidium ore with Rb2O grade of only 0.048%was directly subjected to chlori-nation roasting-leaching to obtain qualified rubidium chloride products.In order to reduce the comprehen-sive processing cost and improve the development and utilization value of rubidium resources,the explora-tion test of beneficiation pre-concentration of rubidium resources was carried out for the low-grade rubidium ore.The test results show that under the condition of grinding fineness of-74 μm 65%and neutral flotation,the mass ratio of sodium dodecyl sulfate to coconut oil amine is 1∶1 as the combined collector,and the rubid-ium concentrate with Rb2O grade of 0.102%and Rb2O recovery of 60.99%is finally obtained by one rough-ing two scavenging,roughing and scavenging concentrate combined one cleaning flotation process.
