This paper shows some results of statistical description and analysis of operation of fourteen hydroelevator rinsing tools with deep sluices, processing the placer deposits' gold-bearing sands. The life service of these tools is from one to four seasons. There was made an attempt of generalization and comparison of season-averaged indicators: granulometric characteristics of metal released in concentrate, sluice coefficient, theoretical extraction of metal and quantity of extracted metal in concentrate. There was carried out the statistic processing of averaged characteristics of the concentrates, obtained as a result of more than 3800 removals. There is shown the strong linear correlation between the indicators of calculation extraction and coarseness medians of gold particles. As a result, the chief engineer's service should pay attention on two specialintended rinsing tools. A close positive connection of average values of sluice coefficient, metal release and coarseness median with their standard deviation values was found and may be practically used for indicator fixing. A diagram method is offered for assessment of rinsing tools operation. It is based on calculation of arithmetic average parameter values at the end of the season and definition with their significant increasing by current (special) values. Assessment of these indicators, synchronized with sequence and order of raw material extraction is the most urgent. Generally the obtained results may be the part of new approaches and methods, aimed on increasing of efficiency and rationality of mining of placer gold-bearing deposits.
