铌和钽在特殊合金鋼、噴气工业、无綫电技术以及其他工業部門有广泛而重要的用途,因此寻找铌和钽的矿物原料资源应該是我們目前的迫切任务之一。铌和钽的重要矿石是钶铁矿-钽铁矿族矿物及黃綠石-細晶石族矿物,至于其他多数的铌钽酸鹽矿物或钛铌钽酸鹽矿物,如褐钇钶矿、钶钇矿及黑稀金矿等,一般只是作为钇族稀土类元素的资源来进行小規模开采。因为象褐钇钶矿这些矿物,一般比较分散,很少形成規模巨大的矿床;同时由于这些矿物的化学組成相当复杂,在分离及冶煉方面存在有一定的困难。尤其象黑稀金矿或复稀金矿等含钛高的矿物,铌、钽和钛的分离、提取,是一个尚待研究的問題。但所有
As niobium and tantalum have a wide range of important uses in special alloy steels, jet industry, radio technology and other industrial sectors, the search for sources of niobium and tantalum mineral raw materials should be one of our urgent tasks. The most important ores of niobium and tantalum are the ferro-tantalite minerals and the pyrochlore-fine spar group minerals, while most other niobate tantalum minerals or titanium niobate tantalate minerals such as brown yttrium ores, yttrium Mine and black and thin gold ore, etc., generally only as a resource of rare earth elements of yttrium for small-scale mining. Because such minerals as brown yttrium ore are generally relatively dispersed, seldom form a huge deposit; the same time due to the chemical composition of these minerals is quite complicated, there are some difficulties in the separation and smelting. In particular, the separation and extraction of niobium, tantalum and titanium, such as black-leached gold or complex-leached gold, such as titanium-bearing high minerals, is a subject yet to be studied. But all
