The floatation of niobite has been studied using different collectors at various reagent dosages and solution pHs. The collectors used in this study included octyl diphosphonic acid (ODA), benzyl arsenic acid (BAA), C7–9 alkyl hydroxamic acid (AHA), α-styrolphosphonic acid (SPA), and diisobuty...detailed
A new process is proposed for refining niobite ore that is found in Jiangxi province of China. Niobite, also known as columbite or niobite–tantalite, is a mineral that contains tantalum and niobium. The separation process includes two-stage grinding, gravity concentration, magnetic separation, ...detailed
