本文着重对绿柱石碱法浮选中的若干问题,通过纯矿物及矿石浮选和ξ-电位的测定,阐明了矿浆中某些杂质(离子)的存在,促使绿柱石可浮性发生相应的变化;Ca~(++)是强碱性介质中绿柱石浮选的主要活化因素;CO_4~=(或HCO_3~-)是分选被Ca~(++)活化的绿柱石与脉石矿物具有选择性的抑制因素;适当调整与改变矿浆中的有关离子组成及其比例、合理控制浮选过程的主要活化因素与抑制因素,有效地减弱与克服了矿浆中“难免离子”和矿泥对浮选的不良影响,从而制定了“绿柱石简易浮选流程”,在不同的天然水质(包括硬度达17德度的硬水)中选别各种绿柱石矿石分别获得了良好效果,并已成功地应用于工业生产实践。
In this paper, we focus on some problems in the flotation of feldspar by the flotation of pure minerals and ores and the determination of ξ-potential to clarify the existence of some impurities (ions) in the feldspar, Ca ++ is the main activation factor of beryl flotation in strong alkaline medium. CO_4 ~ (or HCO_3 ~ -) is a kind of beryl and gangue mineral activated by Ca ~ (++) Selective inhibition factors; proper adjustments and changes in the plasma composition and the proportion of ions in the flotation process to control the main activation and suppression factors, effectively reducing and overcoming the “inevitable ion in the pulp and the sludge on Flotation of the adverse effects, which developed a ”simple beryl flotation process" in a variety of natural water quality (including the hardness of 17 degrees hard water) selected various beryllium ore were good results, and has been successful Used in industrial production practice.
