摘要
作者过去曾经提出,不同矿粒在气泡上存在竞争。当然,许多研究者在泡沫相已经发现了这种竞争,但是,还没有证明,在液相中的气泡上存在竞争。Harris 曾经证明,当各种矿物被放在同一系统中时,它们会相互独立地保持自己的浮选速度常数。下列观察的目的是要在不同矿物之间,甚至在不同粒度下同种矿粒之间看看在气泡上有无竞争存在。另外,在建立模型过程中,仍然有某种浮选行为无法解释。例如:某种矿物如黄铁矿。
Using a device developed by the authors,an impact-attachment process between the mineral particles(galena,sphalerite,pyrite,fluorite and barite)and bubbles was investigated. Following phenomena have been observed. The boltom part of bubbles is the most beneticial location for attached particles, therefore the competition will happen in this area.For the same species of a mineral, coarser particles will enjoy more favorable condition since they possess more energy. The competition happened only when the bubb...
