印度有许多钒钛磁铁矿矿床,含TiO_24％～14%,V_2O_5达2％。化学成分随矿床的位置和埋藏深度不同而不同。虽然采用氨盐熔烧-浸滤-沉淀的方法,对钒、钛的回收已进行了一系列实验室试验,但这些矿床迄今还未开发,还未以任何形式来回收钛或钒。本文描述了用得自奧里萨邦库马尔杜比地区的矿石所进行的选矿试验研究。分段磁选的结果是令人鼓舞的。对所得到的矿样,以及加热至350℃的矿样中非磁性部分还进行了浮选试验。试验结果表明,采用磁选一泡沫浮选,可选出和富集TiO_2;同时,钒也可能得到相当程度的富集。
There are many vanadium-titanium magnetite deposits in India, containing 24% ~ 14% TiO_2 and 2% V_2O_5. The chemical composition varies with the location of the deposit and the depth of burial. Although a series of laboratory tests have been conducted on the recovery of vanadium and titanium using the method of ammonia salt melting-leaching-precipitation, these deposits have not yet been developed so far and titanium or vanadium have not yet been recovered in any form. This article describes the beneficiation study using ores obtained from the Dolmar area of Kumar Dolby, Orissa. The result of segmented magnetic separation is encouraging. Flotation tests were also performed on the resulting ore samples, as well as the nonmagnetic fractions in the ore samples heated to 350 ° C. The experimental results show that the magnetic separation of a froth flotation can be selected and enriched in TiO 2; the same time, vanadium may also be a considerable degree of enrichment.
