摘要：
The article presents experimental research of the influence exerted by electrochemical polarization on electrode potential, phase composition of surface compounds, adsorption of collector and floatability of basic sulfides of gold-bearing ore. It is shown that phase composition of surface compounds generated under different polarization modes affects adsorption of collectors and floatability of minerals.
