01/04/1984  Process., 12: 273--284, The size distributions of the products from laboratory-scale batch grinds, of a lead- zinc ore and a tin ore, were measured as a function of pulp density. A reduction in the overall grinding rate at high pulp densities correlated well with the increase in pulp vis- cosity. Enhanced fines production, apparent at the higher pulp densities, was however controlled largely ...

05/11/2020  Pulp density in the mill is approximately 65 pct solids. The purpose of the ball mill is to subject the ore to a differential grind which liberates silica from the iron ore particles, and middling from the ore particles and from silica. It also assists in breaking down porous iron oxide particles. The ground product flows into a 78 in. Akins classifier which makes a size separation at nearly 200 mesh. The
