Socio-Ecological Analysis Of Artisanal Gold Mining In West Africa: A Case Study Of Ghana, Richard Takyi, Rasha Hassan, Badr El Mahrad, Richard Adade
Journal of Sustainable Mining
The surge in artisanal gold mining (AGM) activities and the associated environmental impact in Ghana have elicited several stakeholders' attempts to curb the problem. However, due to little understanding of the underlying issues, these efforts have been ineffective. This study aims to use a socio-ecological framework to analyze drivers of AGM activities, the environmental pressures, the state change, their impact on human welfare, and the management response as measures (DAPSI(W)R(M)) to the problem. Evaluate AGM's impact on Ghana's ability to achieve the United Nations Sustainable Development Goals (SDGs). Data were collected from relevant literature on the subject and analyzed with …
Growth Of Invasive Plant Species Communities As A Substantial Issue In Post-Mining Land Development,

Growth Of Invasive Plant Species Communities As A Substantial Issue In Post-Mining Land Development, Paweł Olszewski
Journal of Sustainable Mining
This article concerns the issue of the appearance and growth of invasive plant species in land degraded by hard coal mining and the repercussions of this process, particularly in the context of land reclamation. These species, such as Canadian goldenrod or Japanese knotweed, which nearly always form extensive and monocultural patches of vegetation, contribute to the displacement of both native species and those introduced as part of biological restoration. In 2015, the Central Mining Institute in Katowice prepared a land development concept for a part of the area of the former KWK Paryż mine in Dąbrowa Górnicza (Upper Silesian Industrial …

Mining Engineering Faculty Research & Creative Works
In order to explore the effect of the attachment site of the benzene ring in the backbone of the surfactant on its diffusion characteristics on the surface of anthracite, the molecular dynamics simulation method was used, and the four isomers (m-C16, m = 2,4,6,8; m represents the attachment site of the benzene ring in the backbone) of sodium hexadecyl benzene sulfonate (SHS) were selected. Binary models of surfactant/anthracite, surfactant/graphene modified by oxygen-containing functional groups, and a ternary model of water/surfactant/anthracite were constructed. By analyzing a series of properties such as interaction energy, contact surface area, relative concentration distribution, radial distribution …

The Factors Impacting The Incorporation Of The Sustainable Development Goals Into Raw Materials Engineering Curricula, Dimitris Damigos, George Valakas, Anna Gaki, Katerina Adam
Journal of Sustainable Mining
It is widely recognised and acknowledged that the mining industry, if properly operating and managed, has the potential to positively contribute to “The 2030 Agenda for Sustainable Development”. In this direction, the Raw Materials (RM) engineering education possesses a crucial role, given the need to instil in tomorrow’s mining engineers the sustainability principles. This paper explores the educational needs of the Greek RM sector and the factors constituting the RM whole value chain SDGs-education-innovation eco-system. The research follows a two-stage focus group approach. First, the perceptions, opinions and beliefs of invited stakeholders were explored in the context of semi-structured interviews. …

Rare earth elements (REEs) are essential raw materials in a variety of industries including clean energy technologies such as electric vehicles and wind turbines. This places an ever-increasing demand on global rare earth element production. Coal fly ash (CFA) possesses appreciable levels of REEs. CFA, a waste by-product of coal combustion, is therefore a readily available source of REEs that does not require mining. CFA valorization to zeolites has been achieved via various synthesis pathways. This study aimed to evaluate one such pathway by monitoring how REEs partition during CFA processing by the wet, magnetic separation process and zeolitisation. South …

Effect Of Shock Vector/Polarization Vector Configuration On The Generation Of Ultrahigh Voltage By Adiabatically Compressed Ferroelectric Materials, Sergey I. Shkuratov, Jason Baird, Vladimir G. Antipov
Mining Engineering Faculty Research & Creative Works
Compact autonomous megawatt-power systems based on shock depolarization of ferroelectric materials are capable of producing kiloampere currents and ultrahigh-voltage pulses with amplitudes exceeding 100kV. Herein, we report the results of experimental investigations of the generation of ultrahigh voltage by poled Pb0.99(Zr0.95Ti0.05)0.98Nb0.02O3 and Pb0.99(Zr0.52Ti0.48)0.98Nb0.01O3 ferroelectrics subjected to shock loading at different shock vector/polarization vector configurations. Our experiments demonstrated that under loading perpendicular to the polarization vector (transverse stress mode) the ferroelectrics are capable of generating high voltages exceeding 400kV, while the loading parallel to the polarization vector (longitudinal stress mode) causes a distortion of the depolarization process in ferroelectrics of large …
