Despite the fact that potential of multi-criteria decision making (MCDM) to overcome a variety problems in mining and mineral processing has been widely recognised, no literature review these fields conducted. This manuscript addresses this issue by providing comprehensive overview applications trends MCDM methods for choice problem (i.e., determining best option from set) processing. 90 articles published between 1999 2017 were selected following searching methodology eligibility criteria...
Sustainability in the mining and raw materials sector is a key target EU Green deal agenda. The aim of this work to determine degree importance risks that may impede sustainable mining, considering UN Sustainable Development Goals (SDGs) indicators initiatives, taking as case study Greece. A total 49 for under six categories, were identified by means expert consultation review literature. identification prioritization potential can provide pathway towards operations. factors weighting...
The use of small hydrocyclones for the separation particles in micron range is growing interest. However, these are typically limited to conventional shapes or restricted specific outlet sizes, which can lead sub-optimal performance. aim this study present a method optimisation hydrocyclone design. This consists four steps that combine designing, Computational Fluid Dynamics (CFD) simulations, 3D printing and experimental testing. A printed 10 mm was shown first match performance ceramic...
The Sustainable Development Goals (SDGs) have been adopted by countries and companies, including mining companies around the world. aim of this study is to investigate degree importance seventeen sustainable development goals on using a rough sets based decision making approach. This novel approach consists three consecutive stages, namely questionnaire (survey), data analyses, SDGs classification. Firstly, survey conducted receive response from internationally experts across different...
Microplastics, particularly those in the 5–20 µm range, pose substantial risks aquatic environments, yet effective removal techniques are limited. This study assesses two critical geometric parameters of a 10 mm mini-hydrocyclone: inlet radius and insertion angle. Along with velocity, they optimised collectively to enhance MPs' removal. Computational Fluid Dynamics (CFD) simulations using Mixture model Reynolds stress were employed track particle–water–air interactions, revealing flow...
The use of renewable energy technologies is a key factor for sustainable development but their selection from several alternatives difficult task that relies on the careful assessment relevant criteria. While Multiple Criteria Decision Making (MCDM) methods have been used successfully in various technology problems, decision process becomes more challenging when preferential judgements are made basis non-homogenous and imprecise input data, there uncertainty due to disparities among makers....
The mining sector is vital for the world's economy and provides an important source of wealth various countries. mines future must adhere to sustainable principles, which rely on applying right technologies. This study evaluates alternatives choosing best process technology, mining, by using interval rough decision-making model, considering four main criteria (cost, efficiency, environmental, social) fifteen sub-criteria. approach was used treat uncertainty imprecision in information,...
A systematic investigation of the influence particle coverage on dynamics rising bubbles was carried out using high-speed photography and image analysis techniques to study bubble behavior in terms changes velocity aspect ratio. The buoyancy force drag exerted effect particles were calculated further understand their behavior. Results show that attached strongly dampen oscillations observed ratio decrease its acceleration. also render more spherical slow velocity. It found overall a is...
The rehabilitation of legacy mines continues to be a big challenge because the difficulties in returning them safe and stable conditions ensuring that mined-out areas become productive support economic activity host community. Previous efforts are often focused on purely technical environmental aspects, leading resistance from local community due their exclusion process. To address issues associated with lack participation community, we have developed project, Biodiversity Positive Mining...
The integration of artificial intelligence (AI) with human (HI) has been asserted to provide transformational power across the humanitarian supply chain (HSC). However, there is little rigorous work that analyses enablers promote AI–HI and application in HSC. Thus, this paper reports a hybrid decision support framework for analysing HSC complicated, uncertain, periodic information. First, collect interdependent preference data from experts, complex spherical fuzzy weighted Heronian mean...
Fluidised bed flotation cells (FBFCs) present a compelling solution for coarse particle flotation, enabling an increase in the target size comminution circuits, with corresponding energy savings. Despite their potential and strong industrial interest, three-phase fluid dynamics of large-scale FBFCs remain unexplored due to measurement complexities restrictions. This paper presents first quantification CoarseAir™-100, 2 m tall laboratory-scale FBFC. Measurements were obtained using positron...
Abstract Material flow analysis (MFA) is used to quantify and understand the life cycles of materials from production end use, which enables environmental, social, economic impacts interventions. MFA challenging as available data are often limited uncertain, leading an under‐determined system with infinite number possible stocks flows values. Bayesian statistics effective way address these challenges by principally incorporating domain knowledge, quantifying uncertainty in data, providing...
In this work, dynamic froth stability is used for the first time to investigate flotation behaviour of copper tailings. Reprocessing material from tailings dams not only environmentally desirable, but also increasingly economically feasible as head grades can be high compared new deposits. Flotation tailings, however, usually contain a large proportion fine (10–50 μm) and ultra (<10μm) effect these particle sizes on yet fully understood. For study, samples were obtained overflow underflow...
