In 2013, a Bord and Pillar Task Team was established by the Department of Mineral Resources (DMR) Principal Inspector of the North West Region, to determine current industry best practice for bord and pillar mining (Platinum Task Team, 2013).
The secondary extraction of pillars from previously mined underground bord and pillar operations dates back to the early 1990s. However, opencast pillar mining is a complex method and entails multiple challenges compared to coal mining, which can adversely affect the process if control measures are not properly implemented (Clough and ...
Any mineral-laden water will generally cause scaling on pipes, fittings, and machinery that it contacts, and this scale can pose a significant cost to business. Mineral scale is deposited naturally in many and varied compositions, while dissolving …

How do mining and mineral-processing operations affect air quality? Tailings ponds dry up, allowing dust to enter the atmosphere, dust from drilling and blasting can get into the atmosphere, hauling rocks from the mine site creates dust in the atmosphere, and erosion of open-pit mines during windy days stirs up dust
• Bord and pillar (1.8 m–2.2 m stope widths using low-profile (LP) mechanized equipment) • Breast mining (1.3 m stope width using extra-low profile (XLP) mechanized equipment) A graphical representation of the bord and pillar and mechanized breast mining methods is shown in Figure 1 and Figure 2. It is important to note that the ...
Evidence of this is seen at Penjom Gold Mine (PGM) in Malaysia, where carbonaceous gold ores are mined and processed. PGM produces one of the world's worst preg-robbing gold ores, …
Abstract: Underground mining technology advancements and automation have progressed significantly in the past 50 years; often the refinement of existing equipment, and the automation thereof, which in effect does the same thing. It's often about progressing mining methods that have incremental impacts, rather than stepchange benefits. Processing, both currently and …
This four-year full-time course in mineral process engineering is open to both local and international students. Mineral process engineering focuses on the safe, economical, and environmentally responsible extraction and processing of mineral resources from the earth, transforming them into more user-friendly forms while minimizing environmental impact.
7. Basis of Sampling For the analytical results obtained to have any validity or meaning it is essential that appropriate sampling procedures be adopted. Thus sampling methods have 3 main groups. Those in which all the material is examined. Causal sampling on ad-hoc basis. Methods in which portions of the material are selected based on upon statistical properties.
