Estimation of mineral liberation distribution functions to be used …
Mineral processing is composed of comminution and then the separation/beneficiation operations, which are closely linked to each other. Comminution processes need input from the beneficiation processes, i.e., target size, solid content, the shape of size distribution curve etc. so that the whole chain can be optimized by means of specific …
Optimizing plant efficiency with attrition scrubbers
Attrition scrubbers may not be glamorous, but they are an important and sometimes neglected step in mineral processing. Optimal attritioning will significantly improve the results and efficiencies of subsequent processing steps and can lead to reduced costs and improved product yields. Why is attrition scrubbing used? Attrition means to wear away a surface, typically by …
Understanding Attrition in Solids Processing
(Page 1) Unwanted breakage, degradation or attrition of solid particles during processing and handling is a ubiquitous issue in the chemical, polymer, pharmaceutical, food, mineral, cement, coal, mining and agricultural sectors. While the fundamental mechanisms of attrition phenomena in solids-handling processes are similar to those well researched in …
