[0002] Gold concentrate refers to ore containing metallic gold. Flotation is a common ore dressing method and is also used to extract gold concentrate. During the flotation process, the gold concentrate is usually crushed and ground, then mixed with one or more chemical reagents and adsorbed or trapped in bubbles by bubbles to achieve separation and concentration of metallic gold.

[0003] However, there are some problems with the existing technology: the bottom of the flotation cell of the mechanical stirring flotation machine used in the mineral processing flotation process is welded from ordinary iron plates, and the high-speed stirring of the slurry directly below the impeller of the flotation machine has a large impact on the bottom plate of the flotation machine, and the bottom plate wears relatively large. In daily production, the bottom plate of the flotation machine is frequently perforated and leaked, and the treatment of the bottom leakage is bound to cause the entire mineral processing system to shut down, which to a certain extent restricts the continuity of production, the equipment operation rate cannot be effectively guaranteed, and the economic benefits of the enterprise are also damaged simultaneously. Therefore, we propose a device to increase the wear resistance of the bottom of the flotation machine cell. Utility Model Content
