The comminution of ores consumes a high portion energy. Therefore, different pretreatment methods prior to their are considered reduce this However, the results and technological development scattered in literature. Hence, paper aims at collating ore with applications from published articles, conference proceedings, verified reports. It was found that include thermal (via oven, microwave, or radiofrequency), chemical additive, electric, magnetic, ultrasonic, bio-milling. Results showed...
The effect of high temperatures on rock's thermophysical and mechanical properties is critical to the design underground geotechnical applications. current work investigates impact temperature rhyolitic turf physical properties. Intact cylindrical core rock samples were heated different (200, 400, 600, 800 °C). uniaxial compressive strength (UCS) elastic modulus unheated determined as important In addition, rhyolite (density, color, absorption) was investigated in conjunction with its...
The combined microwave-assisted sorting and comminution of minerals has been proposed to reduce the huge grinding energy consumption in mineral processing. However, gangue would be discarded after process despite microwave absorbed during their treatment. Therefore, this paper investigates effect pretreatment on Bond work index (BWI) quartz calcite samples, as they represent dominant gangues many ores are key inputs cement industry, which requires intensive grinding. samples were...
Rocks’ physical, mechanical, and mineralogical properties are essential in the design process of underground applications. To understand changes these rocks’ at high temperatures, numerous studies have been conducted on several rock types, with little being known about microschist rock. This paper presents experimental study physical (e.g., density P-wave velocity), mechanical (uniaxial compressive strength (UCS)), microstructural behavior room temperature (22 °C) i.e., 400, 600, 800 °C. The...
ABSTRACT: In open pit mining operations, the decision to select ultimate slope angle is critical due its significant impact on safety and economic outcomes like net present value, mine life, operational costs, risks. Recognizing variability in rock properties discrepancies between planned actual conditions, this paper introduces a robust framework that aligns monitoring of wall conditions with optimizing angles. We proposed use data from geotechnical model conduct stability analysis...
Grinding is an important process of ore beneficiation that consumes a significant amount energy. Pretreating before grinding has been proposed to improve grindability, reduce comminution energy, and enhance downstream operations. This paper investigates hybrid thermal mechanical pretreatment iron behavior. Thermal was performed using conventional microwave approaches, while conducted with pressure device piston die. Results indicate (heating rate: 10 °C; maximum temperature: 400 °C), (2.45...
The discrete cash flow (DCF) model is usually used to estimate the net present value (NPV) of most projects. However, produces results that could be short reality, especially for projects with high uncertainties last decades, as in mining Hence, this paper develops a Continuous Cash Flow (CCF) economic evaluation feasibility gold mine project Saudi Arabia. dynamic DCF also same and obtained from both models were simulated using Monte Carlo technique. Results show CCF lower NPV values than...
