Abstract

Abstract

This is an essay in the field of mining engineering, which introduces the research results of process mineralogy and mineral processing technology of a low-grade rubidium ore from Qinghai Province. By means of chemical analysis, microscopic identification, MLA and electron probe microanalysis, the occurrence of rubidium in the ore is found out. The main useful element of the ore is Rb, and the main rubidium bearing minerals are mica and potash feldspar. On this basis, the combined process of crushing, coarse-grained mica screening, magnetic gravity gravity flotation was used to separate the ore, and Nb, Ta and Rb were recovered from the ore. The test results show that the lithium, rubidium and cesium in the flotation mica concentrate has good leachability, and the operation leaching rate can reach more than 82%.
