The South African mining industry is one of the largest producers of platinum (Pt) in the world. Workers in this industry are exposed to significant amounts of dust, and this dust consists of particles sizes that can penetrate deep inside the respiratory region. A cross-sectional study was conducted to evaluate dust exposure risk at two Pt mine …

Abstract. Mine-to-Mill optimization is a total systems approach to the reduction of energy and cost in mining and mineral processing operations. Developed at the Julius Krutschnitt Mineral Research Centre (JKMRC) in Queensland, Australia, the Mine-to-Mill approach attempts to minimize energy consumption through the optimization of all steps …

Primary crushers are heavy duty rugged machines used for crushing Run-of-Mines ore (–) 1.5 m and convert them into stones of size 100–200 mm in dimension to make them suitable for further crushing process. Most commonly used primary crushers are gyratory and jaw types.

Portable Crusher for Open Pit and Quarry Operations. The primary use of a portable crusher, i.e., a crusher mounted on crawlers or tires, in the rock and mining industries is to reduce costs by permitting the substitution of conveyor belt haulage for truck or track haulage.

Generally, a Quad Roll Crusher is recommended for a medium size feed material, while the Triple Roll Crusher, with its single roll top stage, is effective for handling larger size feeds. These machines do the work normally assigned to two separate crushers. Typical feed sizes range from 18" – 72" with final product size of ½" – 3".

Coal-breaking Operations. Four prime factors affect the plan for breaking run-of-mine coal as it enters the preparation plant: (1) size of lump, (2) incidence of stone, both in volume and size, (3) friability of the coal, and (4) the preparation operations that follow. Bituminous run-of-mine ranges in size from zero to extremely large lump.

Hence, the main aim of this paper is: first, to develop a three-dimensional RMR model of an open pit mine under active operation based on the extensive field mapping carried out, and then produce ...
