硒和碲是较贵重的稀有元素,它们在现代工业中有着重要的用途。已知硒、碲为黄铁矿矿床中经常的有益伴生组分,为了矿石的合理综合利用,有必要对它们在不同类型矿床中的分布特点进行很好的研究。我国有很丰富的黄铁矿资源,高品位的纯黄铁矿矿石,在化学工业特别是支援农业上,有着特殊的意义。近来我们对某地大型的纯黄铁矿矿床的矿石成分进行了初步研究,兹将所得的若干结论作一简要报导。研究矿区位于某凹陷的东南侧,呈一单斜构 Selenium and tellurium are more expensive rare elements that have important uses in modern industry. It is known that selenium and tellurium are often beneficial associated components in pyrite deposits. For the reasonable utilization of ores, it is necessary to study their distribution characteristics in different types of deposits. China has a very rich pyrite resources, high-grade pure pyrite ore, in the chemical industry, especially in supporting agriculture, has a special significance. Recently, we conducted a preliminary study on the ore composition of a large pure pyrite deposit in a certain place. We will briefly summarize some of the conclusions we have drawn. The study area is located on the southeast side of a depression with a monoclinic structure
