The environmental impacts of mining activities are discussed based on their implications on various aspects of environmental resources, namely: impacts on water quality, ecosystem/loss of vegetation, soil quality, and on the land resource. He indicated that cyanide spills and leakages by mining companies such as Teberebie Goldfields Ltd and Ashanti Goldfield Company Ltd (now AngloGold Ashanti) resulted in polluting the Anikoko, Angonabe, Bodwire and Assaman rivers, all in the western region of Ghana. Different methods of mining have a variety of environmental impacts, ranging from minor to major. Even though there has been poor management of mercury in the process of extraction, but extensive use of the chemical in mining is necessary since it is added to the refined concentrate to form a gold amalgam, which is then heated to separate the gold. Mining activities in Ghana can be grouped into small-scale and large-scale mining. This results in destruction of landscape in the area. releasing ore dust into the atmosphere. Underground mines can also cause subsidence on the surface — the land above begins to sink, usually when underground supports fail in abandoned or inactive mines. In this form of coal e… Mining is a major economic activity in many developing countries such as Ethiopia (Tauli, 1997: UNEP,1997).Operations, whether small or large-scale, are inherently disruptive to the environment, producing enormous quantities of waste that can have deleterious impacts for decades (UNEP, 1997). Surface mining method by small-scale artisans often results in the removal of large quantities of topsoil, leaving the land bare and susceptible to erosion. Assel PG (2006) Evaluating the usefulness of Acacia auriculiformis in ameliorating surface mine degraded lands. side-effects can last after the initial mining operations have ended. Yankson PWK (2010) Gold mining and corporate social responsibility in the Wassa West district, Ghana, Development in Practice 20 (3): 354-366. However, small-scale mining activities are statutorily restricted to only Ghanaians. The study was carried out in the mining communities in Prestea, one of the small towns in the Prestea Huni-Valley District, Western Region of Ghana. local ecosystems. The government should address the weaknesses in environmental policies on mining and strengthen their enforcement in order to realize sustainability of the environment. [32] further states that substrates, usually called the overburden or mine spoil, are often the characteristic of all gold mined lands in Ghana. with electric engines are becoming increasingly popular, with some companies, This in turn leads to soil erosion and destruction of agricultural land. Environmental damages caused by mining activities are as follows: 1. The recommendations mainly focused on the current situation in Prestea Huni-Valley District. MSc Thesis, International Institute for Industrial Environmental Economics, Lund University, Sweden. The paper mainly focused on the mining activities in Prestea in the western region of the country. The amendments focused on revising the corporate tax and royalty rates and limiting the duration for mining lease. District Analytical Report. Learn how your comment data is processed. Another similar study by [12] found lower and reduced content of soil nitrogen (N) and phosphorus (P) when compared to the natural forest, due to the same reason of ecosystem disruption, removal of vegetation and loss of litter layer during mineral mining. Geological Society, London, Special Publications 113 (1): 163-181. As in, every city and town on the Keweenaw has its origins in the copper mining industry extensive. Also, the removal of the topsoil which destroys important soil organisms and disrupts stable soil aggregates and organic matter have been other significant threats to the productive use of the land. [3] reported that surface mining concessions have taken over 70% of the total land area of Tarkwa, a mining community in western region of Ghana.
