摘要: 在鞍钢齐大山铁矿近几年来浮选生产实践的基础上,通过研究现场浮选系统处理能力即浮选处理量和浮选时间、一次扫选精矿的返回量及产品的粒度组成,进一步分析造成一次扫选精矿返回量增高,导致指标波动的原因。  

关键词: 反浮选, 浮选粒度, 一次扫选精矿

Abstract: Based on the recent years' flotation practice of AnSteel Qidashan Iron Mine, the causes for the fluctuation of flotation indexes due to the high return amount of the primary scavenging concentrate are analyzed by investigating the site flotation system capacity or flotation throughput, flotation time, return amount of the primary scavenging concentrate, and product size composition.

Key words: Reverse flotation, Flotation size, Primary scavenging concentrate
