适当的精矿品位和不断提高精矿回收率是有色矿山浮选厂获得最佳经济效益的重要产出技术指标。影响这种技术指标主要取决于人选原矿的物质组成(工艺矿物的性质)和与之相适应的各浮选工艺参数。而浮选的各工艺参数又受到多因素的影响和干扰,如何控制这些变量,排除干扰,稳定操作,继而使之最佳组合。选矿自动控翩是实现这一目标的一个有效途径。我矿目前是年处理量10万吨采选能力的有色矿山,主要产品为铅精矿、锌精矿及 Appropriate concentrate grade and continuous improvement of ore concentrate recovery rate are the important output technical indexes for the best economic benefit of non-ferrous mining flotation plant. The impact of this technical indicator mainly depends on the material composition of the candidate ore (the nature of the process mineral) and the corresponding flotation process parameters. The flotation process parameters in turn affected by many factors and interference, how to control these variables, eliminate interference, stable operation, then make the best combination. Automatic Pina processing beneficiation is an effective way to achieve this goal. At present, mine is a non-ferrous mine with an annual capacity of 100000 tons of mining and dressing capacity, the main products are lead concentrate, zinc concentrate and
