One of the most important skills in flotation operations is to observe the foam and judge the effectiveness of the flotation based on the changes in the foam. Experienced flotation operators can determine the cause of the change by observing the various changes in the apparent phenomenon of the foam, so as to ensure that the flotation process is carried out under optimal conditions.
Whether the flotation worker can correctly adjust the flotation agent addition amount, the concentrate scraping amount and the medium ore circulation amount depends on his correctness in judging the appearance of the flotation foam, and the ability to observe and judge is mainly from Continuous and serious summary of operational experience gained. The appearance of flotation foam includes the foam's virtual, size, color, luster, shape, thickness, strength, fluidity, sound, etc. These phenomena are mainly caused by the type, quantity, particle size, color, gloss and density of the minerals attached to the surface of the foam. , the amount of foaming agent and so on. The appearance of the foam varies with the flotation area, but specific areas often have specific phenomena. Observing the foam situation should capture several well-characterized tanks that have a major impact on concentrate quality and recovery. The main ones are: final concentrate production tank, the first few tanks of operation, each dosing tank and sweeping tail. Slots, etc.Dongguan Sun Pak Packing Product Ltd. , https://www.dgsunpak.com
