The article examines the influence of preliminary ultrasonic treatment (PWT) on the results of gravitational beneficiation of gold-bearing ore in a centrifugal concentrator. As an object of research, ore characterized by the presence of finely dispersed gold in pyrite and a high content of slimy minerals was used. Enrichment was carried out on the “Knelson” KC-MD3 laboratory concentrator. A comparative analysis of the classical circuit and the circuit using 5-minute ultrasound showed that ultrasonic exposure does not lead to improvement of technological indicators, but causes their stable decrease. The extraction of gold into the combined concentrate decreased from 27.62% to 25.53%, and the gold content in it decreased from 9.22 g/t to 8.41 g/t. The work proposes a hypothesis about the complex reasons for this influence, both related to the deterioration of pulp rheology and the possible overgrinding of fragile gold-containing pyrite.
