Description

Technical Field

[0001] The present invention relates to the technical field of side-blown furnaces, and in particular to a slag recovery and processing device for a side top-blown furnace. Background Art

[0002] As a commonly used industrial equipment, side-blowing furnace is widely used in steelmaking, ironmaking and other industries. As a commonly used industrial equipment, side-blowing furnace is widely used in steelmaking, ironmaking and other industries. It stirs and mixes the liquid metal in the furnace by blowing gas, so as to achieve the purpose of improving the temperature uniformity in the furnace, promoting the reaction process and improving production efficiency.

[0003] In the side-blown furnace copper smelting process, slag recovery is an important link. Its main purpose is to improve the copper recovery rate and reduce resource waste. The general slag recovery process includes slag cooling, crushing and grinding, flotation, and copper concentrate recovery. During the flotation process, flotation agents need to be added to the slurry to make the surface of the copper mineral hydrophobic so that it can attach to the bubbles and float to the surface to form copper concentrate foam, while the gangue minerals remain in the slurry.

[0004] In the existing slag recovery technology, after adding flotation agents during flotation, it is necessary to wait for the foam to drive the copper concentrate to gradually move upward to the discharge port. This process is relatively slow. Most of the time, the slurry and flotation agents are stirred by rotating the stirring rod. Although the mixing speed is accelerated, due to the certain viscosity of the slurry, the single stirring method is prone to insufficient stirring during the stirring process, which reduces the slag recovery efficiency. In addition, the flotation agent is poured into the stirring equipment. Since the slurry contains sediment, it will settle at the bottom of the furnace tank after a long period of accumulation, resulting in the failure to fully utilize the resources and affecting the overall economic benefits.
