Shrinking-core model for pig iron nugget production
Minerals & Metallurgical Processing - Tập 28 - Trang 24-32 - 2011
Considerable effort has been directed towards understanding the carbothermic reduction mechanisms of self-reducing, fluxing dried green balls to produce pig iron nuggets. Given the geometry of the situation, some investigators believed that the shrinking core model was applicable. Hence, this study involved investigation of the applicability of the shrinking core model to pig iron nugget productio...... hiện toàn bộ
Simultaneous mercury capture and silver leaching using Ag2S-bearing ores and residues
Minerals & Metallurgical Processing - Tập 31 - Trang 181-185 - 2014
Since mercury is chemically similar to silver, it tends to dissolve along with the silver and gold during cyanide leaching. Ultimately, mercury is recovered along with the silver as mercury/silver/gold amalgam, which requires retorting to remove the mercury prior to refining the silver and gold. A possible approach to separating mercury from silver and gold in cyanide leach solutions is to take ad...... hiện toàn bộ
Investigation of Machine-Mounted Area Lighting to Reduce Risk of Injury from Slips-Trips-Falls for Operators of Mobile Surface Mining Equipment
Minerals & Metallurgical Processing - Tập 37 - Trang 1919-1930 - 2020
Nonfatal injuries from slips, trips, and falls (STF) that occur at surface mines can result from inadequate lighting. Mobile equipment operators are among the occupations associated with the nonfatal incidents reported to the U.S. Mine Safety and Health Administration (MSHA). In addition, getting on/off the equipment (ingress/egress) frequently adds to the highest proportion of nonfatal incidents....... hiện toàn bộ
Application of bentonitic clays in suspension fertilizer formulations
Minerals & Metallurgical Processing - Tập 8 - Trang 55-55 - 1991
Characterization of Goldstrike ore carbonaceous material
Minerals & Metallurgical Processing - Tập 16 - Trang 37-43 - 1999
Carbonaceous materials (CM) from ores of varying preg-robbing activity from Barrick Goldstrike Mines Inc. (BGMI), Nevada, were characterized in terms of their functional group contents, hydrocarbon contents, elemental compositions and humic acid contents. Fourier transform infrared (FT-IR) analyses did not show the presence of hydrocarbons orcarboxylic, phenolic or suljhydrol functionalities. The ...... hiện toàn bộ
Variation of specific rates of breakage of coal-water slurries with changing slurry density determined by direct tracer measurement
Minerals & Metallurgical Processing - Tập 8 - Trang 73-76 - 1991
Spectroelectrochemistry of enargite I: Reactivity in alkaline solutions
Minerals & Metallurgical Processing - Tập 32 Số 1 - Trang 6-13 - 2015
Evolution Regularity and Control Technology of Coal Face Rupture Induced by The movement of Overlying Strata Under the Influence of Mining
Minerals & Metallurgical Processing - Tập 40 - Trang 435-452 - 2022
We address the problem of rib spalling caused by mining-induced roof movement. This problem affects production and safety of the working face. We address this problem by using the 3DEC numerical software to simulate the distribution and evolution regularity of displacement, stress, and the extent of plastic zone in the overlying strata and coal face during the advancing excavation of the 10,905 wo...... hiện toàn bộ
Application of Thermal Fragmentation in Australian Hard Rock Underground Narrow-Vein Mining

Adapting technology to beneficiate a low-grade phosphorite ore
Minerals & Metallurgical Processing - Tập 4 - Trang 14-18 - 1987
A flotation process has been developed to successfully treat ore from the Santo Domingo phosphate deposit in Baja California Sur. The ore contained less than 4% P2O5 with quartz, silicates, and carbonates as gangue minerals. Flotation of the low-grade feed in seawater required that the conventional Crago process, comprising direct anionic flotation, deoiling, and inverse cationic flotation, be aug...... hiện toàn bộ
