Fresh ore samples frori-I Shinkai copper ore site were collected, crushed and grinded. Different mesh sizes were analyzed for densities and the concentrations of copper. Point of zero charge (PZC) of the ore was determined as a fUlTCtion of temperature (293 - 323 K) and was observed to decrease with temperature for all the mesh sizes. The mineral assay of the solid showed that the concentration of SiOz decreases while the concentration of copper increases with decrease in the particle size of the ore.
