The evaluation of haulage truck size effects on open pit
This thesis investigates the effects of equipment size selection on the economics of open pit mining. The work presented, illustrates the importance of considering equipment selection in the wider context of the entire mine. A methodology is presented for evaluating the various variables that are affected by equipment size, Equipment Size Sensitive Variables, (ESSV) that will aid the industry ...

Laser Induced Breakdown Spectroscopy (LIBS) is a geoanalytical tool capable of identifying elements, and measuring element concentrations and the composition of rock samples. LIBS is a method based on a laser energy pulse that creates an ablation in the surface of a rock sample and the ionization of photons to produce a breakdown of the sample’s elemental composition. The ionization process ...
Optimal and energy efficient operation of conveyor belt
2016/07/08 · Downhill conveyors are important potential energy sources within conveyor belt systems (CBSs). Their energy can be captured using regenerative drives. This paper presents a generic optimisation model for the energy management of CBSs that have downhill conveyors. The optimisation model is able to optimally schedule three configurations of a case-study CBS that is connected to the …

Comminution circuit design and simulation for the development
The application of High Pressure Grinding Roll (HPGR) in comminution circuits is well established in processing cement, diamonds and iron ore. Recently, the application of HPGR has been extended to high-tonnage precious and base metals operations with hard ore. This is due to the HPGR: being more energy-efficient than grinding mills, not requiring steel grinding media, and providing higher ...
Application of simulation techniques in development planning
The mining industry globally is moving towards exploiting more mineral deposits by underground methods for several reasons.
