Abstract
It is shown that high processing losses of a valuable component during sand washing and low efficiency of waste use as secondary raw materials reduce the rational use of mineral resources of placer gold mining. The concept of increasing the efficiency of combined low-waste process flow charts for the recovery of free fine gold and the separation of non-ore ephelial, clay and pebble products during the beneficiation and processing of rebellious metal-bearing sands is proposed. A scientific and technological substantiation of flow charts for the integrated use of dump waste products for the creation of resource-saving technologies at placer gold mining facilities with a purpose of using them as secondary mineral raw materials in the construction industry has been completed.
