“Ecological and technological aspects of use of water recirculation at extraction of precious metals from quartzites”

The examination of the worked out technology of beneficiation of gold bearing quartzites and exploration of full water rotation during the technological process was the main purpose of this research. It is established, that at the continuous process of a counterflow washing of leaching tails with gold and silver sedimentation from the first thickener's overflow on anion resin AM-2B, multiple use of barren solution in the process of leaching and washing of the dissolved precious metals without decrease of production data is possible. Laboratory and technological researches of concentration tailings of quartzites from Madnneuly deposit showed, that they can be used as the main raw materials for production of silicate wall materials (lime sand brick, manufactured product from heavy cellular concrete).
