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 ...
Separation of huntite and hydromagnesite from magnesite in combination of physicochemical treatment and size reduction
(Elsevier Science Bv, 2019)
Huntite and hydromagnesite are important minerals in the synthesizing of fire-safe composites. They are mostly not pure and associated with gangue minerals like magnesite, dolomite, aragonite and calcite. In this study, ...
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 ...
Redox behavior of galena in alkaline condition
(Springer Heidelberg, 2018)
Electrochemical potential determines types of redox products formed on electrically conducting minerals like galena, which might manipulate process efficiency applied on the target mineral. Therefore, electrochemical ...
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 ...
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 ...
Relating rock mass properties with Lugeon value using multiple regression and nonlinear tools in an underground mine site
(Springer Heidelberg, 2019)
The Lugeon test is one of the commonly applied field methods for measuring hydraulic conductivity of a rock mass. Understanding hydraulic conductivity is especially necessary when groundwater is present, as it has a direct ...
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 ...
