Open-Pit Mine Optimization with Maximum Satisfiability
Minerals & Metallurgical Processing - Tập 36 - Trang 757-764 - 2019
A common casualty of modern open-pit mine optimization is the assurance that the resulting design is actually achievable. Optimized mine plans that consider value and a bare minimum of precedence constraints do not, in general, translate into practical, operational mine designs that can be used in the field. Ultimate pits may come to a sharp point at the bottom. Schedules may require taking small ......
Equilibrium analysis of carbon dioxide absorption in alkali solutions
Minerals & Metallurgical Processing - Tập 29 Số 2 - Trang 131-132 - 2012
Corrosive and Erosive Wear in Magnetic Taconite Grinding
Minerals & Metallurgical Processing - Tập 1 - Trang 10-14 - 1984
The relative significance of corrosive and erosive wear in magnetic taconite grinding is examined. The influence of different types of aeration (nitrogen, air, and oxygen) on hall wear was established for mild steel and high carbon low alloy steel balls. Ball wear data from dry and wet grinding tests are compared with those obtained in the presence of an organic solvent that does not promote elect......

Results of an Opioid Hazard Awareness Training Intervention for Stone, Sand, and Gravel Miners
Minerals & Metallurgical Processing - - 2021
In the USA, miners are at higher risk for work-related disorders that could precipitate an opioid prescription, injury-related opioid prescriptions, and opioid overdose. We aimed to support prevention of these outcomes with an “opioid hazard awareness” miner safety training module. In January and February 2020, the training module was embedded within required mining safety and health training for ......
Bulking Based Porosity Method to Predict Floodable Volume of Longwall Gob
Minerals & Metallurgical Processing - Tập 38 - Trang 1845-1859 - 2021
The floodable volume of longwall gob can be of great importance in developing accurate coal mine operation plans, particularly for mine water management and environmental control strategies. Given the inaccessibility and difficulty in direct measurement of gob characteristics following gob recompression, hydrologic, geomechanical, and spatial data and principles were used to solve for the porosity......
Mineworkers’ Perceptions of Mobile Proximity Detection Systems
Minerals & Metallurgical Processing - Tập 36 - Trang 647-655 - 2019
Accident data indicates that mobile haulage poses a significant pinning, crushing, and striking risk. Proximity detection systems (PDSs) have the potential to protect mineworkers from these risks. However, unintended consequences of mobile PDSs can undermine the safety benefit they provide. Soliciting iterative user input can improve the design process. Users help provide a critical understanding ......
Novel Scaling Methods for Modeling In Situ Leaching
Minerals & Metallurgical Processing - Tập 2 Số 2 - Trang 127-136 - 1985
Review of electrical separation methods
Minerals & Metallurgical Processing - Tập 17 - Trang 23-36 - 2000
The fundamentals of electrical separation, the electrical properties of minerals, the principal methods used for charging minerals and their mechanisms, the effective factors controlling the acquisition of charges by minerals, the general configuration of commercial electric separators and the forces operating during electrical separation of minerals are reviewed and presented.
