Gold-tellurium-bismuth mineralization of various types рrecious mineralization in ferruterous quartzites and interore shale of the Kursk Series KMA

Abstract

By the research of technological probe from different genetic types of рrecious mineralization in BIF and shales of the Lebedinsky and Stoylensky iron deposits were established the different mineral forms of the native gold, sulfides, bismuth, tellurium and others In slates native gold with a silver ligature which is divided into 2 groups (generation) is revealed: with lowered (800-820 ‰) and raised (more than 850 ‰) fineness of gold. In quartzites gold of 2 generation is emitted (medisty and high-standard gold with a silver ligature). Considerable concentration of Au are in sulfides (pyrite).
