Production of White Barite from Barite Concentrates of Shaking Tables by Bleaching Process after Magnetic Methods
(Polish Mineral Eng Soc, 2018)
Market price of industrial minerals depends on the purity of products, and increases almost exponentially with the decrease in grade of coloring impurities. Therefore, this work was conducted to investigate the applicability ...
Optimization of an industrial scale open circuit three-compartment cement grinding ball mill with the aid of simulation
(Elsevier Science Bv, 2016)
An industrial scale FLSmidth (R) three-compartment cement grinding ball mill operating in open circuit was sampled at the steady state conditions. The three-compartment ball mill was modelled by using the perfect mixing ...
Prediction of cementitious grout take for a mine shaft permeation by adaptive neuro-fuzzy inference system and multiple regression
(Elsevier Science Bv, 2017)
Cement grouting is a common technique implemented for permeation and ground improvement in civil and mining engineering projects. Basically, it is the injection of cement and water mixture into a fractured rock mass. Due ...
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 ...
Investigation of design parameters of a failed soil slope by back analysis
(Pergamon-Elsevier Science Ltd, 2017)
A soil slope instability occurred at the surface facility area of a mine site, which was successfully managed from occupational health and safety point of view, and no human or material loss was encountered. Three different ...
Investigations into tilt angles and order of cutting sequences for cutting head design of roadheaders
(Pergamon-Elsevier Science Ltd, 2018)
This paper explains optimum arrangement of gauge tools and corner cutting picks for cutting head design of roadheaders. Full-scale simulation of roadheaders cutting heads of practical types with a wide range of tilt angles ...
High-temperature electrocoagulation of colloidal calcareo-argillaceous suspension
(Elsevier Science Bv, 2018)
In this work, the temperature-dependent electrocoagulation behavior of the highly stable calcareo-argillaceous colloids was studied. The response surface methodology was implemented to explain the performance of this ...
Performance evaluation of a conventional closed circuit process at different cement productions
(TMMOB Maden Muhendisleri Odasi, 2017)
Performance of a conventional Polysius® two-compartment ball mill and a OSepa® high efficiency dynamic air classifier (FLSmidth) closed circuit process was investigated at the steady state conditions at CEM II type Portland ...
Analysis of the self-similarity of single particle impact breakage distributions of cement clinker particles
(TMMOB Maden Muhendisleri Odasi, 2017)
This study analysis how the impact breakage pattern changes at different specific comminution energy levels. Impact breakage patterns of two different cement clinker samples were investigated by plotting size-normalized ...
A rational comparison of groove deepening to relief cutting in terms of tool spacing with drag tools
(TMMOB Maden Muhendisleri Odasi, 2017)
This paper mentions a rational comparison between relief cutting and groove deepening for tool lacing design of partial-face cutting machines employed for mechanical excavations of rocks, coal and stones. The comparison ...
