Leaching process for copper concentrates The University

In this specification and claims, the term P80 describes the particle size at which 80% of the mass of material will pass through the specified size of mesh. For use in the leaching process, the P80 particle size of the chalcopyrite concentrate can vary over a wide range. For example, a P80 particle size of about 210 microns can be used.

Industrial: Powder Metallurgy Production and Properties

The particle size distribution is influential in determining the flow and packing of powders. The apparent density is the weight of a unit volume of the powder under specified conditions. It is a function of the size, shape and particle size distribution and is also influenced by the relative surface area and the packing properties of the powders.
