This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.

Research On Copper-molybdenum Ore Flotation Separation Process

The natural floatability of molybdenum ore is good, so the molybdenum ore beneficiation process of direct flotation after crushing and grinding is often used.

The Importance of pH in Flotation

This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation, it is necessary to be able to determine which and to what degree it is. A cheap way to take this measurement, LITMUS PAPER or a pH METER is used. This is a very important measurement for the flotation operator.
