Abstract: As part of developing a technology for complex extraction of valuable components from sands of placer gold deposits, a laboratory research was conducted aimed at justifying a method to produce bulk concentrates of heavy minerals from sands of placer gold deposits. Processing of bulk concentrates is supposed to be carried out by gravitational and physicochemical methods. A sluice box with continuous bulk concentrate discharge was designed and manufactured. During the sluice box testing and adjustment of its operating modes in laboratory conditions, bulk concentrates containing up to 34.7% heavy minerals were obtained from samples of placer deposits in the Khabarovsk Krai, with up to 80% in –0.2 + 0.0 mm size fraction. It was established that –0.2 + 0.0 mm size fraction is the most productive in terms of the presence of associated valuable components.

Keywords: placer gold deposit, heavy minerals, bulk concentrate, associated valuable components, sluice box with continuous concentrate discharge, mineralogical analysis, electron microscopic examination
