一、简要回顾建国初期,我国多金属硫化矿浮选厂普遍采用优先浮选流程,药剂制度比较简单,使用法连瓦尔德型浮选机。第一个五年计划初期,国内推行快速浮选的经验。在几个老选厂中强调正规作业,保持稳定的细度与浮选浓度,进行合理装球与正规的加药制度,稳定浮选作业条件,使有用矿物在粗选区得到快速 First, a brief review The early days after the founding of China’s polymetallic sulfide flotation flotation plant generally preferential flotation process, the pharmaceutical system is relatively simple, the use of law and even the Wald flotation machine. In the early days of the first five-year plan, the domestic experience of implementing rapid flotation was introduced. In several old factories emphasize regular operations, to maintain a stable fineness and flotation concentration, a reasonable ball loading and formal dosing system, stabilizing flotation operating conditions, so that the useful minerals in the rough area to get fast
