The existing ideas about the nature and mechanism of losses of nickel and cobalt with converter slags allow us to consider that for effective depletion of slag should be created conditions that provide intensive recovery of slag components, effective coalescence of fine inclusions, the possibility of transition of recovered and separated from the slag particles containing non-ferrous metals in the phase-collector ...
In modern pyrometallurgy of non-ferrous metals one of the most important places belongs to the converter process, which, along with ore smelting, is the main node of the pyrometallurgical scheme of nickel and copper production. At the USSR plants, converting is used to process copper, copper-nickel, nickel, polymetallic and cobalt matte, as well as ferronickel.
Essence of metallurgical furnace operation. Modern metallurgical furnaces are most properly regarded as complex physical and chemical units, in which a whole complex of diverse in nature processes occur. If we combine these processes into their most characteristic varieties, we can distinguish the following: technological, heat exchange, energy, movement of gases, movement of materials and products. All of them proceed in the working space in close mutual connection and mutual conditionality and often coincide in their purpose and definition. For example, the technological process of oxidation of sulfides is simultaneously and energetic, providing the necessary for the operation of the furnace heat release. The movement of molten slag in ore-thermal electric furnaces is simultaneously a process of convective heat exchange in the bath. The main of these processes, of course, is technological, so the basic parameters of metallurgical furnaces and the development of all processes in them should provide the technological process optimal flow conditions with the best qualitative and quantitative indicators.
