The comminution at the grain size level for liberating valuable minerals usually requires highest size-specific energy. Therefore, a full understanding of process this is essential. Models based on Discrete Element Method (DEM) can become helpful tool purpose. One major concern, however, missing representativeness mineral microstructures in simulations. In study, method to overcome limitation p...
Chemical composition and liberation are critical attributes in characterizing a resource stock for beneficiation investigations. Though end-of-life printed circuit board is recognized as a valuable secondary resource stock, no procedural standard exists for the determination of its chemical composition, nor for the -75 microm fines generated during its comminution. The effect of the digestion p...
Bone Joint J 2013;95-B, Supple A:11–16. Received 5 September 2013; Accepted after revision 6 September 2013 Total hip replacement (THR) after acetabular fracture presents unique challenges to the orthopaedic surgeon. The majority of patients can be treated with a standard THR, resulting in a very reasonable outcome. Technical challenges however include infection, residual pelvic deformity, acet...
The relation between breakage mechanisms and liberation is critical in mineral processing. Recent studies underline the importance of texture in liberation. This study reviews relevant liberation models and proposes a new method for generating particles using image processing algorithms. One new texture simulation method and its relevance for liberation simulation is also introduced.
In this research, the efficiency of the comminution circuit as well as the efficiency of size classification equipment of the concentrator plant 2 of Sarcheshmeh copper complex was studied. The comminution circuit of this plant includes one SAG mill in a closed circuit with a vibrating screen and one ball mill with a size classification system of hydrocyclone. The goal of this work was to calcu...
