Methodology for a Dump Design Optimization in LargeScale

This paper presents a methodology to optimize the ultimate dump design in a mining operation by minimizing the unit haulage cost using a linear algorithm and Mine dumps are made up of a complex mixture of metals and dust particles This means that dust exposure can be high for communities living nearby, particularly during windy conditions and whenHow mine dumps in South Africa affect the health of

Maintaining the stability of the dump may require relocation of weathered rock or material blending, especially if water is present (Russell, 2008) • If it is a dump leach, a leaching cycle time will define the mining delivery rate and dumping schedule Ideally, deliveries rate from the mine should match the leaching cycle times of the dumpWORKPLACE COMPETENCIES Plant manager Crushing and screening Diesel Mechanic Frontline Management Internal course undertaken at Lumwana Mining Company this includes training and assessment in a number of areas including personnel management, reporting requirements, financial management, safety and environmental management Shawn Potgieter Process Plant Manager / Acting COO LinkedIn
