摘　　要：通过考察金属离子对硅线石和微斜长石可浮性的影响，发现Ａｌ３＋对微斜长石的活化作用干扰了两种矿物的浮选分离，这是影响矿物浮选分离的主要因素；同时还发现Ｆｅ３＋对Ａｌ３＋活化微斜长石有一定的屏蔽作用，并可通过控制ｐＨ值范围实现矿物较为有效的分离。The effect of metallic ions on the flotation behavior of sillimanite and microcline has been studied in this paper. It shows that the activation of Al 3+ to microcline is the key problem in the flotation. It also shows that Fe 3+ can certainly resist to the disturbance of Al 3+ in the flotation. Sillimanite and microcline can be separated by controlling the values of pH.
