Is measuring pH enough?

This paper provides the reader with a number of pulp chemical observations in several plants, showing that the same trends are noted over time; however, the magnitude of the measured values do change. Further, the changes in magnitude are invariably associated with a change in mineralogy.

Grinding Media – Its Effect on Pulp Chemistry and Flotation – Fact or Fiction?

This paper explores the science behind these corrosion reactions, and provides an explanation of their impact on the pulp chemistry of sulfide mineral slurries and subsequent flotation behaviour. Laboratory and plant case studies are used to illustrate the benefits of changing to a more inert grinding media.
