Mineral Extraction, Mineral Processing, Concentration

Ball mill grinding efficiency is influenced by many factors: ore grindability, feed size, grinding product size, ball mill diameter and length, ball mill working speed, liner type, steel ball loading system, grinding concentration, return sand ratio in closed-circuit grinding and feed rate. 2021-03-26 10:03:21.

Unearthing hidden value using pre-concentration

Pre-concentration relies on heterogeneity in the ore. That is, at some scale, there must be discrete higher-grade and lower-grade zones in the ore that have the potential to be separated. For example, there may be discrete veins of valuable minerals within poorly mineralized host-rock or sulphide breccias containing clasts of unmineralized rock.
