2020-5-8  Mining has played a part in the economic development of developed countries such as the USA, Canada and Australia. However, the mining economic growth connection varies considerably from that claimed in the historical analogy reasoning. It is not evident that these countries’ historical experience applies to modern developing nations due to modifications in the nature of the world economy.

Impacts of mining on the environment; some local,

The mining, processing and utilisation of metals dates back to Roman times and earlier with extensive developments in many parts of the world by the eighteenth and nineteenth centuries. Many mineralised areas are no longer worked leaving a legacy of dereliction and contaminated land and drainage.

Environmental impact of quarrying of building stones

2020-7-14  Mining and quarrying for minor minerals impart significant economic, environmental and social impacts in and around the affected areas. The problem is severe in the small river catchments as the effective area available for assimilating negative impacts of the activity is minimal, compared to large river basins. To address these issues, an investigation has been carried out in two river basins

Environmental Geochemistry of Igarra Marble Mining

The determination of the impacts of marble mining on the environment in Igarra was carried out via the analysis of soil and water samples as geological medium. Seven soil samples, ten water samples and five rock samples were collected. The samples collected were subjected to petro-graphic and geochemical analysis. The mean concentration of metals in soil from Ekpeshi were Cd (3.254 mg/kg), Co

ORIGIN OF TANZANITE AND ASSOCIATED

Tanzanite is the blue vanadium-bearing variety of zoisite. The only known source of gem-quality tanzanite, to date, is the Merelani area of northeastern Tanzania, a structurally complex region consisting of granulite facies metacarbonate and metasilicate rocks

Phosphate induced Fluorosis a Global Geohealth Issue

High concentration of fluoride in the groundwater is observed to be associated with granitic aquifers as well as near phosphate mines around the globe. The present work is a hydrogeological study of the ground water of Beldih phosphate mines in India. Being located in the Singhbhum shear zone the area has a complex tectonic history and is dominated by phosphate, alkali granites, amphibolites

Environmental impact assessment of open pit mining

2008-8-26  Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and open-pit mining in particular. As such, a repeatable process to evaluate these effects primarily aims to diminish them.

What Are the Advantages and Disadvantages of Mining?
