【 摘 要 】

This article describes the result analysis of gold in pyrite for a number of some Altai - Sayan folded belt gold deposits. The analyzed pyrite samples showed gold grade from 0.04 to 20.0 g/t., which proves the fact that the gold concentrations in pyrites is irregular. Pyrites in productive mineral associations include significant metal enrichment, while pyrites of early poor gold-bearing associations and wallrock metasomatites are less prolific.
