Results of an Opioid Hazard Awareness Training Intervention for Stone, Sand, and Gravel MinersMinerals & Metallurgical Processing - - 2021
Cora Roelofs
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 ...... hiện toàn bộ
Bulking Based Porosity Method to Predict Floodable Volume of Longwall GobMinerals & Metallurgical Processing - Tập 38 - Trang 1845-1859 - 2021
Joshua M. Silvis, Greg J. Hasenfus, Allison M. Haines
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...... hiện toàn bộ
Mineworkers’ Perceptions of Mobile Proximity Detection SystemsMinerals & Metallurgical Processing - Tập 36 - Trang 647-655 - 2019
Jennica L. Bellanca, LaTasha R. Swanson, Justin Helton, Michael McNinch
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 ...... hiện toàn bộ
Review of electrical separation methodsMinerals & Metallurgical Processing - Tập 17 - Trang 23-36 - 2000
H. R. Manouchehri, K. Hanumantha Rao, K. S. E. Forssberg
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.
Evaluation Index System of Green Surface Mining in ChinaMinerals & Metallurgical Processing - Tập 37 Số 4 - Trang 1093-1103 - 2020

The concept of green mining is to improve the mining industry in a holistic way so that it is safe, efficient, and environmentally sustainable. The purpose of this study was to develop an evaluation index system of green surface mining based on the theory of green grades. The evaluation model is comprised of three attributes (safety, efficiency, and environment), nine criteria, and 35 indicators. ...... hiện toàn bộ
Hydrolytic Stripping of Versatic Acid Solutions Containing Iron and Other MetalsMinerals & Metallurgical Processing - Tập 2 - Trang 47-51 - 1985
F. M. Doyle-Garner, A. J. Monhemius
Hydrolytic stripping is the process whereby metal ions in a loaded solvent extractant are hydrolyzed by water, typically at 130°C to 200 °C (265°F to 392°F). Equilibrium hydrolytic stripping tests were done on Versatic 10 solutions containing various metals, singly and in mixtures. Single solutions of Fe, Ni, Cu, mg, and Mn precipitated αFe2O3 Ni(OH)2 Cu2O + CuO, Mg(OH)2 and γMn2O3 respectively, d...... hiện toàn bộ
