研究确定,浮选矿浆中存在着相同粒度的微细矿粒,但其水化度却因晶格状态不同而异。细泥的浮选活性取决于疏水程度,因而减小矿物表面上水化层的厚度理应提高细泥的浮选活性。改变矿粒表面水化层结构和状态的一种可行方法是浮选时采用无机电解质。核磁共振分析表明,在0.5克分子/升的氯化钠浓度下,亲水矿物(石
The study determined that flotation pulp exists in the same size of fine mineral particles, but its hydration degree due to different lattice states. Fine flotation activity depends on the degree of hydrophobicity, and thus reduce the thickness of the hydration layer on the mineral surface should increase the flotation activity of fine mud. One possible way to change the structure and state of the surface hydration layer is to use inorganic electrolytes for flotation. Nuclear magnetic resonance analysis showed that at a sodium chloride concentration of 0.5 mol / L, the hydrophilic mineral (stone
