googling:
the flotation method is to achieve separation by adjusting the surface properties of ore and gangue minerals in water so that they are selectively adsorbed or inhibited. the flotation method grinds the ore into fine particles and mixes it with water and flotation reagents to form a flotation suspension. the function of the flotation reagent is to change the properties of the surface of the mineral particles, so that the hydrophobic spodumene particles are adsorbed on the bubbles and rise to the liquid surface, forming spodumene flotation foam, while the gangue minerals sink to the bottom. separation of spodumene from gangue minerals is achieved by collecting spodumene particles on the foam.
therefore, the gravity separation method achieves separation through density differences, while the flotation separation method achieves separation through surface property modulation. gravity separation is more suitable for co**** separation based on the density difference of minerals, while flotation separation is suitable for selective separation of minerals at the fine particle level. which method to choose depends on the characteristics of the ore, particle size, impurities in the ore and other factors. sometimes multiple separation methods are used in combination to improve the separation effect and extraction rate.
