Preliminary assessment of new approach to scale-up the laboratory results of flotation reagents tests based on mineralogical analysis

Abstract

The question of introducing new collectors into copper concentrator plants referring to KGHM experience has been presented in this paper. Description of present methodology of flotation reagents testing has been indicated followed by explanation of crucial problems and limitations with proper qualification of reagents. Some attempts to apply scale-up methodology have been reported in technical literature. In this article assumptions of new methodology based on advanced mineralogy tests have been suggested. This methodology should allow the more accurate forecast of flotation performance of industrial plant after the laboratory tests.
