THE ASSESSMENT OF THE CONTENTS OF GOLD IN ALLUVIAL TECHNOGENIC DEPOSITS

Наумов В.А., Илалтдинов И.Я., Наумова О.Б., Кольцов В.А.
Man-triggered deposits formed during the development of placer gold hydraulically. Sand-and-gravel-clay deposits are distributed regularly and form a cone reclamation of dumps. Studies conducted on Chernorechenskaya placer of Southern Urals. Three types of precipitation concentrations in man-made piles are installed: a massive, lenticular cross streams, lenticular longitudinal jets. Type of scattering sediment is uniform. Gold placers in the development of gravitational ways not fully recovered. Gold lost during washing, concentrated in alluvial technogenic deposits. The direction of maximum variability in the concentrations of gold (heavy fraction) are arranged radially from the battle zone flow hydraulic unit. Testing of the concentration zone of gold reveal cost-effective sites for redevelopment and recovery of gold. Rainfall zone of scattering can be used to create a filter dams.
