| 摘 要： | 余庆县小腮地区的钒矿赋存于下寒武统牛蹄塘组近底部,具有品位低、厚度大的特点,矿石类型属炭质泥岩型钒矿.钒在原矿中的价态主要以V^3＋形式存在,其次为V^4＋和V^5＋,其中V^3＋主要以类质同象形式取代Al^3＋、Fe^3＋等氧化矿物及硅酸盐矿物,而V^4＋、V^5＋则全部以吸附状态赋存于云母类矿物中.矿石通过“原矿—破碎—磨矿—浸出—固液分离—萃取—反萃—沉钒—脱铵—五氧化二钒成品”提钒工艺,其五氧化二钒浸出率达85％,五氧化二钒总回收率为79.20％,在环境保护上能得到较好的控制,所得产品质量达GB3283-87冶金用V20599牌号标准.

| Abstract: | V deposit in Xiaosai area occurs in deep Niutitang formation of Lower Cambrian, has the features of low grade and high thickness, the ore is carbon mudstone typed V deposit. In the primary ore, V existed in the form of V^3＋, than V^4＋ and V^5＋, V^3＋ replaces Al^3＋, Fe^3＋, oxide minerals and silicate minerals in the form of isomorph, but V^4＋ and V^5＋ occurs in mica minerals. By the extraction technology of ＇ primary ore - crack - ore grinding - solid-liquid separation - extraction - back extraction - jarosite - ammonium remove- vanadium pentoxide＇, the extraction ratio of vanadium pentoxide is 85%, the total recovery is 79. 20%, the environment protection can be controlled, the product is up to V20599 standard of GB3283. |
