“…Moreover, the environmental consequences of mining such as pollution and ecosystem damage are crucial factors that should not be overlooked. For instance, uncontrolled bauxite mining in Malaysia has led to severe environmental degradation, prompting the government to impose a temporary ban on mining activities (Rahmat et al 2022). This underscores the signi cance of comprehensive Environmental Impact Assessments (EIAs) and decision-support frameworks, such as the Analytic Network Process (ANP), to guide sustainable mining practices (Rahmat et al 2022).…”

The concept of sustainability in mining is multifaceted and often lacks a universally accepted de nition, leading to speci c approaches for assessing sustainability (Phillips 2012).…”

The extractive industry has a profound impact on the environment, emphasizing the need for environmentally friendly practices. This study employs a mixed-methods approach to evaluate the environmental impact of bauxite and iron mining projects in Boke and Kerouane, Guinea. Primary data were collected from October 2022 to January 2023, with a focus on water pollution, soil, noise, air quality, vegetation, fauna, and flora. A reference matrix was used to assess the impact of mining activities, categorizing them as negligible, moderate, or significant. This study analyzed 400 soil samples from 21 sites to evaluate water quality, measured noise levels using an NL52 Class 1 sound level meter, and monitored air quality using the DustMate system. Biodiversity surveys were conducted to identify potential impacts on the receptors. The results showed that the pH of the water averaged between 5.79 and 8.66, and some companies exceeded the average value of electrical conductivity. The soil composition showed the presence of Cr, Cu, Ni, and Zn in both the mining regions. Noise and particulate matter pollution exceeded the guideline values at some sites. This project will result in the direct loss of natural and modified habitats, including erosion of lateritic soil in ridge areas. Non-native plant species have been identified in the Kerouane Iron Project. This study underscores the need for policymakers to integrate climate change mitigation strategies into land use planning and use an integrated index of economic and environmental performance to improve sustainability in the mining industry.

“…thorium is a naturally occurring radioactive heavy element, widely distributed in nature as an easily exploitable resource in many countries. It found in a variety of minerals, such as monazite, xenotime, zircon, and ilmenite [ 3 , 4 , 5 ]. Some human activities, such as nuclear fuel plants, ore mining, tin processing, rare-earth extraction process, production of phosphate fertilizer, phosphate rock processing, industrial boilers, coal-fired utilities, and laboratories dealing with radioactive substances, contributed to an increase in the concentration of thorium in our environment as a result of waste generated from such activities [ 6 , 7 , 8 , 9 ].…”

The natural zeolite has been modified with sulphate and phosphate. The adsorption of thorium from the aqueous solutions by using the natural and modified zeolites has been investigated via a batch method. The adsorbent samples were characterized by X-ray Diffraction (XRD), N2 adsorption–desorption (BET), Fourier transform infrared (FTIR), field emission scanning electron microscopy (FESEM), and energy dispersive X-ray spectroscopy (EDX). Modification of natural zeolite with sulphate and phosphate was found to increase its adsorption capacity of thorium but reduced its specific surface area (SBET). The adsorption experiments were expressed by Langmuir, Freundlich and Dubinin–Radushkevitch (D–R) isotherm models and the results of adsorption demonstrated that the adsorption of thorium onto the natural and modified zeolites correlated better with the Langmuir isotherm model than with the Freundlich isotherm model. The maximum adsorption capacity (Qo) was determined using the Langmuir isotherm model at 25 °C and was found to be 17.27, 13.83, and 10.21 mg/g for phosphate-modified zeolite, sulfate-modified zeolite, and natural zeolite, respectively. The findings of this study indicate that phosphate-modified zeolite can be utilized as an effective and low-cost adsorbent material for the removal of thorium from aqueous solutions.
