摘要

研究了电浮选从氨水碱性溶液中回收铜、锌、镍的混合物。结果表明，针叶木油皂等阴离子表面活性剂可将处理时间缩短4-5倍，延长pH范围，形成更稳定的泡沫产物，从而提高了氢氧化物混合物的电浮选回收率。提出了一种描述金属氢氧化物分散相表面电荷形成、表面活性剂和配体吸附及其对电浮选过程影响的方案。

Electroflotation Recovery of a Mixture of Cu, Ni, and Zn Hydroxides from Aqueous Ammonia Alkaline Solutions

Electroflotation recovery of a mixture of copper, zinc, and nickel hydroxides from aqueous ammonia alkaline solutions was studied. It was shown that such an anionic surfactant as tall oil soaps from coniferous wood improves the efficiency of the electroflotation recovery of the mixture of hydroxides by decreasing the process time by a factor of 4–5, extending the pH range, and forming a more stable froth product. A scheme was proposed to describe the surface charge formation, the surfactant and ligand adsorption on the dispersed phase of metal hydroxides, and their influence on the electroflotation process.

期刊介绍： Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
