摘要：
It was experimentally determined that dispersed gold droplets during heating by an external source move toward the ore surface in pores under the action of the thermocapillary pressure. After melting of the gangue, the gold droplets are floated by gas bubbles. The flotation is accompanied by coalescence. As a result, gold is concentrated on the surface of the oxide melt, and particles are coarsened to sizes allowing gold recovery by gravity methods.
