Abstract
This paper presents the results of laboratory agitation and percolation leaching studies of rubidium (Rb) and other associated elements (uranium and rare earth elements) from rock samples and ore-bearing horizon core samples using sodium hypochlorite (NaOCl) solutions. The effects of reagent concentration, process duration, filtration rate and liquid-to-solid (L:S) ratio on the recovery of the components were investigated. In addition, the chemical composition of the pregnant solutions and the concentrations of the elements were determined quantitatively by inductively coupled plasma optical emission spectrometry (ICP-OES) and atomic absorption spectrometry.
