钒在工业上的重要性,已如前文.(见第八期)所述。近三十来,各国的技术家无时不努力寻找钒矿资源,以图满足当前的迫切需要。然而已发见的矿脈毕竟不能算多,而且矿石的性质也颇复杂,提炼起来,颇不容易。今就个人所知,约略说明资源地域,矿石性质,和钒提炼法的大要。资源含钒矿石在地壳中的分布,原极广汛,大部分的火成岩、砂岩、页岩、以及淘土、铁矾石等,凡含有矾石和氧化铁的铁矽酸盐质的矿石中,大概都含有少量的钒矿石。然而大多因钒的含量太低
The industrial importance of vanadium is as described above (see Issue 8). In the past 30 years, technicians from various countries have made every effort to find vanadium resources so as to meet the urgent needs of the present. However, the veins have been seen, after all, can not count, and the nature of the ore is also quite complex, refined up, quite easy. Now, to the best of my knowledge, we have a brief description of the geographical area of resources, the nature of the ore, and the law of vanadium extraction. Resources Vanadium ore in the crust in the distribution of the original extremely broad flood, most of the igneous rocks, sandstone, shale, and Amoy, alum and other stones, containing ferrosilicon and iron oxide iron ore, Probably contain a small amount of vanadium ore. However, most of the vanadium content is too low
