This study was carried out to investigate the effect of illegal small-scale gold mining ( Galamsey ) operations on the water quality of the Akantansu and Sintim rivers in the Asutifi North District of the Brong-Ahafo Region of Ghana. Water samples were collected from the two rivers for physico-chemical and heavy metal analyses
Artisanal and Small-Scale Mining occurs in approximately 80 countries worldwide. There are approximately 100 million artisanal miners globally. Artisanal and small-scale production supply accounts for 80% of global sapphire, 20% of gold mining and up to 20% of diamond mining (World Bank, 2013)
Oct 28, 2015 Though artisan miners always argue that mining occurs on a relatively small portion of land, it contribution to land degradation is enormous. Osafo (2011) findings also indicated the effects of artisan mining on the environmental has a detrimental effect on the nearby water bodies and soil
4 Plate 4: A Current water impoundment: underneath the body of water is the course of the Mutare River Plate 5: Water Resources Degradation by Gold Panners in Mutare River Issues that came up after much probing during the interviews were the effect of alluvial gold mining on underground water and whether operations at Redwing have had at any point in time an effect
Impact of Gold Mining Activities on Water Quality of the Lower Pra River ’is the outcome of research work undertaken by myself under the supervision of Prof. V. K. Nartey and Dr. R. K. Klake and that it has neither in part nor in whole been presented for another
Mineral exploitation contributes significantly to economic growth and development in most world economies. In Africa, Ghana is the second largest gold producer, contributing to about 5.7% of the country’s GDP. The mining sector in Ghana consists of both small-scale and large-scale mining, each of which has varying environmental impacts. This paper provides an exposition
Dec 17, 2016 Impacts on the river started in the post war era when logging and irrigated agriculture moved into the watershed, gravel was mined from the riverbed in the lower reaches and then, in 1964, the Mt Washington Copper Mining Co. moved into the upper Tsolum watershed. The company began a small open-pit copper mine adjacent to the Tsolum River
Feb 07, 2017 Artisanal and small scale mining (ASM) is an important source of income for millions of poor people around the world. The past decade has seen increasing numbers of individuals and households turn to ASM, and this trend is likely to grow in the face of high mineral prices, population growth, poverty and climate change

Jan 26, 2016 The source of these elevated levels of As, Cd, Mn, Pb and Hg in water samples from the study area is attributable to artisanal small-scale gold mining (ASGM). For instance, though As and Cd are naturally occurring metals, they are also associated with gold-bearing ores in the study area and are often found at elevated concentrations near gold
May 28, 2015 Impact of artisanal small-scale mining . Artisanal small-scale mining (ASM) operations feature a number of rudimentary practices that pollute air and contaminate resident water bodies and soils, for example through the use of mercury (Hilson & Van der Vorst 2002).Mercury is used for gold amalgamation in artisanal mining
Mar 26, 2002 In Ghana, small-scale (gold) mining is defined as, “Mining by any method not involving substantial expenditure by an individual or group of persons not exceeding nine in number or by co-operatives society made up to ten persons or more.” In this study the term artisanal mining is defined as mining with the use of manual methods and procedures
Jun 16, 2021 On Tropical River, Goix et al. have shown the impact of some artisanal and small-scale gold mining. The study combined two different models to discriminate the part of the anthropogenic Hg in bottom sediments of tropical rivers affected by ASGM and the part of liquid Hg used by gold-miners in the anthropogenic Hg sources

The study examined the effects of the activities of Small Scale Mining on the environment in the Tarkwa-Nsuaem Municipality. A simple random sampling technique was used to select 123 small scale gold miners in the municipality. The study also ascertained why people engage in SSM and determined the effect of SSM on the environment
Aug 16, 2018 Small-scale mining by the artisanal and small-scale mining sector (ASM) has expanded rapidly in Ghana. More than 60% of the total mining labor force is in this sector. The ASM in 2014 produced about 34% of exported gold (compared to 9% in 2000) making it a major sector of the Ghanaian economy and an important source of livelihood and income for
