ABSTRACT The prohibition of river sand mining has drawn the attention researchers in finding practicable alternatives. In approach these alternatives, it is essential to ensure minimal or zero impairment ecological balance, which can be mainly attained by making use industrial waste/byproducts. wastes from industry are major contributors causing environment, and their influence on stability mortars using as fine aggregates needs systematically investigated with view long-term performance concerns. Thus, present study explores applicability mine tailings optimum dosage cement investigating engineering properties microstructure development aid qualitative quantitative analysis associated hydration products. studies confirm that increased consumption portlandite for secondary reactions followed additional formation calcium silicate hydrate (CSH) aluminum (CASH) phases tailing-based helped achieving a quality microstructure. These formations CSH CASH also confirmed through Fourier transform infrared spectroscopy identifying shift Si-O-Si stretching vibration bands toward lower wavenumber. lowering calcium/silicate atomic ratio mineralogical compounds related x-ray diffraction patterns confirms same.

Published: April 24, 2024

The recent tailings storage facility (TSF) dam failures recorded around the world have concerned society in general, forcing mining industry to improve its operating standards, invest greater economic resources, and implement best available technologies (BATs) control TSFs for safety purposes avoid spills, accidents, collapses. In this context, as era of digitalization Industry 4.0 continues, monitoring based on sensors become increasingly common industry. This article studies state art implementing sensor monitor structural health management issues TSFs, highlighting advances experiences through a review scientific literature topic. methodology applied adheres Preferred Reporting Items Systematic Reviews Meta-Analyses (PRISMA) guidelines utilizes maps data visualization. To do so, three steps were implemented: (i) quantitative bibliometric analysis, (ii) qualitative systematic literature, (iii) mixed integrate findings from (ii). As result, presents main advances, gaps, future trends regarding characteristics TSF digitalization. According results, existing research predominantly investigates certain technologies, such wireless real-time monitoring, remote (RS), unmanned aerial vehicles (UAVs), survey vessels (USVs), artificial intelligence (AI), cloud computing (CC), Internet Things (IoT) approaches, among others.

Published: Jan. 6, 2025

Abstract Due to the widespread application and development of copper, there is growing concern about increasing pressure on available resources significant environmental repercussions. To support improvements in copper mining, this study addressed life cycle assessment concentrate production from cradle gate, along with feasibility tailings reuse, which has received less attention. fill a critical gap, alternative use building landfilling disposal was also conducted. Sodium hydroxide (36.63%-95.22%), (4.73%-99.4%), carboxymethyl cellulose (0.06%-46.35%) were identified as main contributors. Marine ecotoxicity prioritized terms burdens (31.28%) followed by human toxicity freshwater potential. It interesting note that photovoltaic systems treated wastewater provided required energy water for production, alleviated final impacts. For management, it initially found intensified impacts 1.67–65.15 times higher than processing. However, utilization cement road construction benefits conserved resources. Summing up, additional insights into indicators industry efficiency future applications.

Coastal Environments: LiDAR Mapping of Copper Tailings Impacts, Particle Retention of Copper, Leaching, and Toxicity

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(5), P. 922 - 922

Published: March 5, 2025

Tailings generated by mining account for the largest world-wide waste from industrial activities. As an element, copper is relatively uncommon, with low concentrations in sediments and waters, yet very elevated around operations. On Keweenaw Peninsula of Michigan, USA, jutting out into Lake Superior, 140 mines extracted native Portage Volcanic Series, part intercontinental rift system. Between 1901 1932, two mills at Gay (Mohawk, Wolverine) sluiced 22.7 million metric tonnes (MMT) copper-rich tailings (stamp sands) Grand (Big) Traverse Bay. About 10 MMT formed a beach that has migrated 7 km original pile to River Seawall. Another 11 are moving underwater along coastal shelf, threatening Buffalo Reef, important lake trout whitefish breeding ground. Here we use remote sensing techniques document geospatial environmental impacts initial phases remediation. Aerial photos, multiple ALS (crewed aeroplane) LiDAR/MSS surveys, recent UAS (uncrewed aircraft system) overflights aid comprehensive mapping efforts. Because natural quartz basalt stamp sands silicates similar size density, percentage sand determinations utilise microscopic procedures. Studies show beaches contrast greatly physical, chemical, biological characteristics. Dispersed particles retain copper, release toxic levels dissolved concentrations. Moreover, leaching exposure high DOC pH characteristic riparian environments. Lab field toxicity experiments, plus benthic sampling, all confirm serious on aquatic organisms, supporting removal. Not only should companies end discharges, advocate they adopt UNEP “Global Management Standard Mining Industry”.
