Surface Characterization of Oleic Acid Coated Marble Dust
(Polish Mineral Eng Soc, 2020)
Calcite, being the most abundant mineral on earth crust, have wide application areas especially in polymer industry as a micronized functional filler material. It is hydrophilic in natural form, and made hydrophobic after ...
Field evaluation of flexible support system with radial gap (FSRG) under a squeezing rock condition in a coal mine development
(Springer Heidelberg, 2020)
A wide range of alternatives is available to design a support system to stabilize an underground opening under squeezing conditions. An underground mine development was selected for the research where the underground ...
Suggested methods for optimum rotative motion of point attack type drag tools in terms of skew angles
(Taylor & Francis Ltd, 2020)
Rotation of point attack picks in their tool holders is of crucial importance for an efficient performance of machines used for tunnelling and underground excavations of rocks and coal. With current machines, skew angle ...
Influence of time-dependency on elastic rock properties under constant load and its effect on tunnel stability
(Techno-Press, 2020)
In structures excavated in rock mass, load progressively increases to a level and remains constant during the construction. Rocks display different elastic properties such as E-i and v under different loading conditions ...
Ocena potencjalu pozyskania zmikronizowanego kalcytu z odpadów z bia?ego marmuru
(J.J. Strossmayer University of Osijek , Faculty of Electrical Engineering, Computer Science and Information Technology, 2020)
Natural calcium carbonates have a great importance in the world's economy due to their numerous applications areas such as calcium carbonate in the paper and paint industries. The final calcite products have rigorous quality ...
Quartz bleaching by phosphoric acid: An investigation on the relationship between Fe rejection rate and colour response
(Pergamon-Elsevier Science, 2021)
Advances in high-tech industries have led to increasing the demand for highly pure quartz. Research on thebeneficiation of quartz has been conducted to meet market requirements by different processes including hydrometal ...
Advances on the fragmentation-energy fan concept and the swebrec function in modeling drop weight testing
(MDPI, 2021)
The breakage index equation (BIE), or t10 model from drop weight testing (DWT) data for rocks and ores is used in the design of crushers and mills. Such models are becoming increasingly difficult to visualize as the number ...
Combined effect of pyrometallurgical and hydrometallurgical processes on quartz ore purification
(Chamber of Mining Engineers of Turkey, 2021)
Recent advances in high-tech applications have highlighted the growing demand on highly pure silicates like quartz. Therefore, purification of quartz ore was determined as the subject of this study performed by pyrometallurgical ...
Phase variation and mechanical properties of waste calcium carbonate to substitute quartz in composite slab production
(John Wiley and Sons Inc, 2023)
Owing to the fast-emerging nature and rapid advancements in the construction industry, huge volumes of marble dust (MD) are generated as reject during slab cutting in marble processing, causing significant environmental ...
Susceptibility to cyanidation of pyrrhotite-associated gold in pyrite calcines from (non)oxidizing roasting environments
(Elsevier Ltd, 2023)
The susceptibility to leaching of pyrrhotite-associated gold in roasted pyrite calcines was studied, with emphasis on the effects of the roasting environment and galvanic contacts under cyanidation conditions. The first ...
