研究时用钒酸铵(NH_4VO_3)溶液作浮选对象,每升含V10～50毫克,用盐酸松香胺(FXAK)作钒离子的捕收剂。FXAK配成0.4％的水溶液,按化学计量加入钒酸铵溶液,小心搅拌1～2分钟后开始浮选。捕收剂与所回收的离子间的作用很快,并且形成稳定的松香胺钒缔合物的胶体溶液。在浮选过程中,钒离子的成分转移到溶液-气体的相界面。浮选在φ40,高500毫米的玻璃柱中进行。柱底用梭那4号过滤漏斗,全部注入柱中的溶液容积为100毫升,充气速度为1微立方米/秒。浮选时间10分钟。
Study with ammonium vanadate (NH_4VO_3) solution for flotation objects, containing 10 mg per liter V, with rosin hydrochloride (FXAK) as vanadium ions collector. FXAK dubbed 0.4% aqueous solution, stoichiometric ammonium vanadate solution, carefully stirred for 1 to 2 minutes after the start of flotation. The collector and the recovered ions act very quickly and form a stable colloidal solution of the rosin amine vanadium association. During the flotation, vanadium ions are transferred to the solution-gas phase interface. Flotation in φ40, 500 mm high glass column. The bottom of the column with shuttle filter that funnel No. 4, all the solution into the column volume of 100 ml, inflation speed of 1 micro cubic meters / second. Flotation time 10 minutes.
