Description

Technical Field

[0001] This utility model relates to the field of flotation agent purification technology, specifically a mixing device for flotation agents. Background Technology

[0002] Flotation is an effective means of mineral separation and a good method for desulfurization of bauxite. It can make comprehensive use of mineral resources. During flotation, various reagents are used to adjust the physicochemical properties of the feed minerals and the flotation medium, thereby expanding the difference in hydrophilicity and hydrophobicity between the minerals and gangue. The minerals can selectively adsorb onto the mineral surface. By increasing the hydrophobicity of the mineral surface, it is easier for the minerals to adhere to the air bubbles, which is beneficial to improving the floatability of the minerals. This can lead to better separation and thus improve the recovery rate.

[0003] After flotation of minerals using flotation reagents, the used reagents need to be mixed for reuse, which saves costs. Since the flotation reagents have been used once before mixing, impurities are present in the reagents to be mixed. Therefore, these impurities need to be filtered during the mixing stage to ensure the flotation reagents can be reused. Thus, it is essential to provide a flotation reagent mixing device to meet the mixing requirements of flotation reagents. Utility Model Content
