自然界缺乏具有工业价值的钪矿物,目前钪资源主要来源于钪钇石、铀钍矿、钨锡矿、钽铌矿、钨精矿、钛铁矿、铅土矿等矿物中。由于钪的分布极为稀散,含量都在干分之几,万分之几或十万分之几的复杂原料中。在综合回收时,由于含量少,组分复杂等持性,致使钪的回收成本高,价格昂贵。在应用方面受到很大的限制。 The scarcity of scandium minerals with industrial value is lacking in nature. At present, the scandium resources mainly come from the minerals such as scandium yttrium stone, uranium and thorium ore, tungsten and tin ore, tantalum and niobium ore, tungsten concentrate, ilmenite and lead earth ore. As the distribution of scandium is very scattered, the content is dry, a few thousandths or a few thousandths of the complex raw materials. In the comprehensive recovery, due to less content, complex components such as holding, resulting in high recovery costs of scandium, the price is expensive. In the application of great constraints.
