The existing ideas about the nature and mechanism of losses of nickel and cobalt with converter slags allow us to consider that for effective slag depletion conditions must be created that provide intensive reduction of slag components, effective coalescence of fine inclusions, and the possibility of transition of recovered and particles released from the slag containing non-ferrous metals into the collector phase. ...

When creating a pyrometallurgical unit one must take into account such an important factor as the nature of the movement of slag melt in it, which means both the direction and power of slag flows, and the degree of mixing of the melt in different zones of the unit. ...

The correct choice of an optimal design of the depletion unit (geometry of the furnace space, location and depth of the tuyeres, etc.) is not possible without knowledge of the nature of slag movement, especially its degree of mixing. In this regard, cold modeling of the motion of the slag bath in a continuous slag depletion process was carried out ...
