In studying of the in situ gravitational concentration process part feature for placer, the technological ability to transform the in situ massif placer structure is evident. The two main processes involved in altering the massif in situ have been examined and outlined in detail. The in situ disintegration of massif material results in a new massif gravitational stratification structure. Regularities of the distribution of particles in the array of alluvial gold in situ were obtained. These regularities showed us the possibilities for direct formation of zones with elevated gold concentrations. The disintegration feature separates particles in an aqueous medium and concentrates the full exemption in situ particulate matter within the placer massif. This method will reduce the volume of mining and ore processing and increase profitability.
