摘要/Abstract

摘要：

在湖北渔塘坝硒矿床氧化矿石及地表松散堆积物中存在大量罕见的次生自然硒。自然硒呈柱状、板状和它形粒状。它的形成一方面与硒矿石的风化作用有关，另一方面系当地居民用石煤烧石灰过程中导致硒的蒸发而发生次生富集的结果。矿床中大量次生自然硒的发现，不仅对硒的矿物学、矿床地球化学、环境地球化学研究具有重要价值，而且对解决或改进含碳硒矿石或岩石中硒的冶炼回收工艺流程具有一定的启迪意义。

Abstract:

The secondary native selenium was discovered in the Yutangba Se deposit, western Hubei Province, China, which is one of rare selenides in the world.The native selenium produced is so large in scale and it varies morphologically. It can be divided into three types such as pillar, tablet and grain based on the crystal forms of the mineral. The forming genesis of native selenium is the result of selenide oxidating from reriching selenium ores in natural factor condition, or selenium evaporizing from burning of “stone-coal” during manufacturing calcareousness.The occurrence of native selenium found in the deposit would be helpful not only to futher study on mineralogy, ore geochemistry and environmental geochemistry of selenium, but also to improve on technology of reclaiming selenium from the black rock series.
