硒矿资源研究现状

The Studying Situation on Selenium Resource and Its Exploiting and Utilizing Prospect

硒系分散元素之一 ,在自然界通常极难形成工业富集 ,甚至硒的独立矿物也很少 ,其主要来源于综合性含硒矿床。目前硒已广泛应用于各个领域 ,国际市场对硒的需求量逐年增长。世界硒矿资源严重短缺 ,且其分布不均匀 ,供求矛盾比较突出。在我国加强硒矿资源的勘查和开发利用已刻不容缓。

Selenium is one of the dispersed elements and it is not easily enriched to such an extent as to be of commercial importance. The occurrence of selenide minerals is even scarce. The primary selenium comes mainly from some selenium-containing deposits. So far selenium is applied to various field extensively such as glass manufacturing, miscellaneous chemical uses, photoreceptors, pigments, electronics, metallurgical application, national defence, agricultural feed additives, medical treatment and health care. Selenium demand has been increasing year after year in international trade. Because world selenium resource is deficient seriously and not well distributed, the contradiction of supply and demand of selenium is very prominence. Therefore, it is urgency for selenium resources to be reinforced exploration, exploitation and utilization.
