Xinhua News Agency Zhengzhou, April 3 (reporter Niu Shaojie)According to the henan Provincial Bureau of Geology and Mineral Exploration and Development, a scientific research team that participated in the bureau discovered and named a new mineral in nature, “empty iron tetrahedrite”, which was approved by the New mineral Naming and classification Committee of the International Mineralogical Association recently.The bureau’s technical staff introduced that the empty tietengeyin mine was found in the Yindongpo gold mine in Tongbai County, Nanyang City, Henan Province. It is the ninth member of the international family of new minerals belonging to “Henan nationality”.After systematic mineralogical studies on physical properties, chemical composition, crystal structure and spectral characteristics, the research team confirmed that the tetrahedrite is a new mineral that has not been discovered in nature.Sample of empty iron tetrahedrite.According to the observation and research, the mineral specimen is gray black, gray under reflected light, and has brown-red internal reflection, opaque metallic luster and black streaked, brittle, closely symbiosis with deep red silver ore, sphalerite, galena, air iron silver tetrahedrite and pyrite and other minerals.According to the introduction, empty iron tetrahedrite is the nature of the most rich silver minerals, silver content up to 52.3%.More importantly, its special structure is regarded as the unsolved mystery of tetrahedrite group by international peers, and its outstanding performance in catalysis, chemical sensing and photoelectric function has become a hot spot in the research field of silver clusters.
