胶磷矿直接浮选工艺已在王集磷矿使用,目前遇到的突出问题是泡沫产品又细又粘,过于稳定。它堆积在浓缩机表面,导致溢流中磷的严重损失,影响生产正常进行。本文试图从理论上分析王集磷矿浮选泡沫过稳定形成的原因,并介绍消除方法及初步试验结果。 一、泡沫的稳定性与王集磷矿浮选泡沫的过稳定性 Phosphate rock flotation direct flotation process has been used in Wangji phosphate rock, the current outstanding problems encountered are thin and sticky foam products, too stable. It accumulates in the thickener surface, resulting in a serious loss of phosphorus in overflow, affecting the normal production. This paper attempts to theoretically analyze the flotation of Wangji phosphate rock flotation causes of stability, and to introduce the elimination method and preliminary test results. First, the stability of the bubble and Wangji phosphate rock flotation over-stability
