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.
