Introduction: The mineral ore processing industry is a sector that can generate pollutants in the form of dust during the production, commonly known as respirable dust.
Environmental impact assessments are made by experts including, environmental engineers, environmental scientists, regional planners, sociologists, and even archeologists who make assessment to propose mining activities on the basis of scientific knowledge, scientific models and a broad knowledge based on past experience.
This study reports on the assessment of the impact of antimony mine wastes from Xikuangshan (XKS) Antimony Mine in Lengshuijiang City, Hunan Province. We focus on the leaching of a number of potentially toxic elements (PTEs) from residues from the processing of antimony ore. The PTE content of ore p …
Mineral processing, metal extraction and metal recovery are the crucial steps required for the extraction of critical metals in the context of re-processing solid …

Purpose The aim of this literature review is to investigate the role of the beneficiation stage in the Life Cycle Assessment (LCA) of metals and minerals with a focus on the flotation process. Methods The systematic literature search included LCA studies comprising the beneficiation stage in their system boundaries and resulted in 29 studies …
Life cycle assessment (LCA) of the mining and mineral processing of iron ore in Australia was carried out in this chapter using SimaPro LCA software as a case study. The environmental impacts considered in the study were embodied energy and greenhouse gas (GHG) emissions, while the functional unit was 1 t of iron ore, ready for …
Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract valuable metals from ore deposits. These …
In the context of iron ore processing, hematite is a mineral of importance and has consequences for ore quality and extraction methods. The research on …
Sensor based automatic ore sorting technologies are used in the minerals industries to efficiently remove waste and submarginal grade material from crushed and screened run-of-mine (ROM) ore, producing a coarse (typically >10 mm) upgraded preconcentrate at an early stage in the mineral processing circuit. This avoids additional energy intensive …
Results on the role of beneficiation in the metal value chain environmental impacts are conflicting, partly because of its site depend-ency. Site-dependent parameters found to …
In summary, the process of ore mining and metal processing involves ore excavation, pulverization and concentration, conversion of concentrates into oxides, …
Quantified textural data including mineral size and distribution have been extracted from mineral maps with the aim of ranking mineral processing behaviour such as liberation and flotation.
To address the environmental impacts caused by the mining sectors, this paper is going to analyse the environmental impacts caused by the 5 major minerals extraction …
Some of the multiple applications of automated mineralogy in mining, mineral processing, geology, geometallurgy, and research are discussed by Sutherland and Gottlieb (1991), Gottlieb (2008 ...

Haldar described mineral processing «as the value-added processing of raw material (run-of-mine ore) to yield marketable intermediate products (e.g. copper concentrate) or finished products (e.g. silica sand) containing more than one valuable minerals and separation of gangue (tailing).»The run-of-mine components consist of the …
The goal of ore sorting technology is to differentiate between ore and waste. Sorting is an age-old practice, with documented examples of hand-picking in the medieval workshops of alchemists (Agricola, 1556) through to modern picking tables at coal mines and fluorescent picking at tungsten deposits.Modern sorting is done mechanically …

of mineral deposits, method of mining and capacity of mines, agricultural activities, forest reserves, etc[2]. Iron ore mining and processing of ore, affects the environment in myriad ways. Figure 3 shows various unit operations of iron ore mines and its associated environmental aspects.
The impact of ore sorting is wide reaching (Allen and Gordon, 2009, Dalmijn and de Jong, 2004, Harbeck, 2004, Riedel, 2006). But to date, very few impact studies have been performed to identify some of these advantages offered by implementing the technology. ...
