Uranium Mining Techniques and Waste Management
European Journal of Sustainable Development Research, 2022, 6(4), em0198,
ABSTRACT: In this paper, mining techniques of uranium were investigated. Basically three type of mining techniques are applied. Basic mining techniques are underground mining, open pit or surface mining and in-situ leaching mining methods. Each of them has several advantages and disadvantages to the other. Specifications of each technique was evaluated in this study. Uranium mine wastes present the most significant waste management problem because of their large volume and their radioactivity. Most of the constituents in these radioactive wastes are found naturally in soils and bedrock. During the uranium mining and milling operations, natural radioactive material changes its chemical and physical form so that their potential for mobility is increased. The mobility results leakage to the environment and the public.

Assessing Social and Environmental Impacts of Artisanal and Small-Scale Gold Mining Practices in Lolgorian, Kenya
European Journal of Sustainable Development Research, 2022, 6(3), em0192,
ABSTRACT: The environmental implications of artisanal and small-scale gold mining (ASGM) practices have significantly grown, particularly on environment, socio, and livelihoods of the mining communities. The study aims to investigates the environmental and socioeconomic consequences of these practices. A survey research design including primary data as well as a random sample process were employed in the study. A total of 250 questionnaires were distributed to randomly selection respondents across the artisanal mining and processing areas. The statistical package for social sciences version 26.0 was used to analyze the data, which included frequency distribution tables, pie charts, bar graphs, percentages, regression, and correlation analyses. According to the data, 97% of gold miners use the mercury amalgamation process, 95.5% operate illegally, and 94.3% do not conduct environmental impact assessments for their mining activities. In terms of ASGM formalization, 68.1% say that poor governance has had an influence on the process, hampered sustainable practices and operations. According to the data, 91.4% of respondents strongly agreed that ASGM provides livelihoods for both women and children, while 73.1% strongly felt that ASGM is more profitable than other forms of livelihoods. The total health implications of hazardous chemical exposure linked with ASGM activities are that 75.5% are aware of major health consequences. Unfortunately, 83.2% of individuals surveyed said they continued to burn amalgam without protective equipment. The environmental implications of ASGM operations have significantly grown, particularly in terms of forest destruction and soil and water contamination (60.4%). The data from model fitting revealed that, at p=0.05, trends, practices, and governance structures were statistically significant with independent variables (X1, X2, X3, and X4) in predicting ASGM environmental sustainability. According to the data, Nagelkerke=0.198, or about 20% of the variance in mining operations in the ASGM sector, may be attributed to the four independent variables. According to the findings of the study, ASGM’s current practices and governance structures have a major influence on the sector’s environmental sustainability. The study suggests that ASGM formalization be accelerated and decentralized, and that governance mechanisms be operationalized in order to improve miners’ skills and knowledge through education and socioeconomic development. Promoting miners’ self-regulation is also essential for ensuring environmental sustainability.

Estimating the Regional Development in Gems Mining Areas in Brazil
European Journal of Sustainable Development Research, 2021, 5(4), em0172,
ABSTRACT: The activity of extracting gems can be improved if public policies are adopted to expand the production chain in Brazil. In theory, the mining activity could be enhanced by increasing the financial collection of the taxes through mineral extraction aligned with the characteristics of the local economy. The present study uses a decision tree model for classifying the regional development of Brazilian states with gemstone mining activities, based on the regional data on financial compensation for mineral extraction (CFEM), gross domestic product (GDP), Human development index (HDI), environmental impact, and geo-tourism applying decision tree models. CFEM, HDP, HDI, and geo-tourism were continuous variables, and the environmental impact was discretized as ‘low,’ ‘medium,’ and ‘high.’ The results indicate that regional development is not only directly related to revenue from the financial compensation for mineral extraction. The GDP and environmental impact also influence regional development. The variables geo-tourism and HDI did not appear to exert influence on regional development. We infer that the increase in taxes would not directly benefit the local government or community from the results. Further initiatives and appropriate public policies would be necessary for planning the adequate distribution of the received resources from gem mining to improve regional growth and development.

Bauxite Mining in the Boké Region (Western Guinea): Method Used and Impacts on Physical Environment
European Journal of Sustainable Development Research, 2019, 3(3), em0087,
ABSTRACT: This study assesses the environmental impact of bauxite mining and the attempts at managing those impacts around the three different bauxite mining communities “zones” (Sangarédi, Boké, Fria) in the western Guinea. Mining sector is important to the country’s economy; it represents 75 to 85% of resources exports by year, especially bauxite and figures prominently in the government's development priorities, evidenced by the broad movement of reforms undertaken by the authorities since 2010. In this context, these reforms aim both to minimize the risks while maximizing the benefits of the mining activity. This implies among other things, a better distribution of income from the mine, strict compliance with environmental standards, to record activity in a sustainable development perspective. To better understand these reforms and scope, this research evaluates the existing framework and innovations of the new reforms in the context of sustainable development. The researcher conducted a data collection, a series of interviews with resource persons (The local communities, the Ministry of Mines, mining companies and NGOs working in the mining sector), to analyze the Environmental and Socio-economic impact of mine. The results showed that the mining code of 1995 was both inadequate and very rarely applied in the field. In contrast, the 2011 code contains advanced Transparency important for equitable sharing of benefits and stringent measures for environmental protection. Thus, this 2011 mining code is more attractive and oriented towards sustainable development.

Perception of the Environmental Degradation of Gold Mining on Socio-Economic Variables in Eastern Cameroon, Cameroon
European Journal of Sustainable Development Research, 2018, 2(2), 23,
ABSTRACT: Artisanal mining is associated with a number of environmental impacts, including deforestation and land degradation, open pits which pose animal traps and health hazards, and heavy metals contamination of land (water and soil), dust and noise pollution. The study examines the perception of environmental degradation of gold mining sites in eastern Cameroon. Human-environment interaction and distance decay models are the conceptual framework for this study.  This study employed a survey research design through the use of primary data while a purposive sampling technique was utilized. A total of 440 questionnaires were administered to selected households across the localities in the study area. Frequencies, percentages, chart, cross tabulations and chi-square tests were used for the data analysis. In other to achieve the aim of this study, a comparison between the nearby and far away residents were done. The study revealed that mining exploitations have brought about changes in the colour and taste of water in the active mining sites (41.7%). Malaria is the number one type of disease that has caused more damage in the localities (81.6%). Mining activities have successfully enabled children in the active mining sites to abandoned school for mining (75.0%). Inhabitants of unit 1 directly linked the problems facing their economic activities to inadequate arable land for agriculture (33.8%) and inhabitants across the study area correlated the problems facing livestock farming to diseases as a result of mining activities (64.6%). The perceived negative effects of gold mining on different socio-economic variables (such as culture, health, education, economy and livestock) vary significantly depending on the proximity from the mining areas (p<0.05). The study concludes that residents living within and far away from the active mining sites were affected by gold mining activities. However, the most worrisome situation concern people working and living within the active mining sites. Therefore, the study recommends that: companies that are involved in mining activities and the government should embark on development projects such as portable water, schools, hospitals, roads, markets, communications facilities in the affected communities.
