Abstract
There are many scientific and practical works related to the identification and assessment of factors affecting the efficiency of beneficiation of placer sands at the sluice box, while the energy consumption of the beneficiation process, as well as assessing the efficiency of the sand screening process and the cost of maintaining the devices, is given little attention. Studies of the energy consumption of sand washing, carried out at several alluvial deposits, made it possible to identify the most energyconsuming devices, as well as to compare the energy expended for transporting rock through processing plants and to provide solid to liquid ratio during beneficiation at sluice boxes.
Highlights
The share of alluvial deposits containing fine and plate-like gold is constantly increasing, and deposits with a high content of clay particles, heavy minerals, as well as technogenic deposits are involved in mining
For the extraction of placer gold, jigging machines, centrifugal concentrators, screw separators have been developed and tested at many enterprises, which make it possible to increase the recovery of precious metals with a grain size of less than 0.2 mm, but still in Russia and abroad the main share of placer gold is extracted at washing devices equipped with sluices [7,8,9,10,11]

Effective development of natural and technogenic deposits is possible only if new technological solutions are used the choice of optimal design and technological indicators of mining and processing equipment (washing devices), depending on the combination of influencing natural, design and technological factors [12-14]. There are many scientific and practical works related to the identification and assessment of factors affecting the efficiency of processing of placer sands at the sluice boxes [15-17], while the energy consumption of the beneficiation process, as well as the assessment of the efficiency of the sand screening process and the cost of maintaining the devices (operating costs) are given little attention
