摘要

本文介绍了在工业规模机械浮选池中研究矿浆固体浓度对气体分散行为影响的试验结果。这些试验是在一家墨西哥矿业公司经营的五个选矿厂进行的，特别是在铅/锌浮选线路较粗糙的河岸。表征了那些对电路性能有重大贡献的机械电池，即能够实现高回收率的电池。测量方案可以测量表面气速，气含率和气泡大小，并对矿浆进行采样。实测数据表明，随着固体浓度的增加，气泡尺寸和气含率减小。

Effects of solids concentration on gas dispersion in industrial mechanical cells

This paper presents the results of tests performed to study the effect of slurry solids concentration on the behavior of gas dispersion in industrial-scale mechanical flotation cells. The experiments were conducted at five concentrator facilities run by a Mexican mining company, specifically in the rougher bank of the lead/zinc flotation circuits. Those mechanical cells having significant contribution to the performance of the circuit, that is, the cells that enable high recovery, were characterized. The measurement protocol enables measurement of the superficial gas velocity, gas holdup and bubble size, and sampling of the mineral slurry. The measured data indicate that bubble size and gas holdup decreases as the concentration of solids increases.
