pH Control in Copper Flotation Application Note for

from the classifier are returned to the mill, while the overflow is discharged to flotation cells. Air is injected into the flotation cells, creating froth. Copper ore particles, due to their relatively light weight, become a part of this froth while heavier particles such as iron ore do not. The copper rich froth is then separated from the solution for further processing. (Figure at right

Spiral Classifier Mineral Processing Equipment

The helical blades on the overflow side are all under the overflow surface. The classifier is suitable for classifying ore materials with a flow particle size between 0.15 to 0.07mm. The sand return side adds an automatic lifting device for returning sand and cancels the ball mill feeding scoop, thus avoiding frequent overhauling.
