Artisanal gold mining AGM is a very important topic of which the environmental and social impact has been widely studied However there are few studies on operational efficiency financial analysis and the lack of mine planning The purpose of this work was to investigate whether AGM operation without mercury is sustainable The following parameters
Studies that solely focused on large scale gold mining were also excluded as well as those that did not focus specifically on the health of the miners themselves Uptake of mercury free techniques has been slow due to large sum of funds needed upfront to install machinery buy equipment or alter operational procedures
Understanding and controlling the ground stress in deep coalfield mining is crucial for ensuring mine safety and efficiency This study aims to address two unresolved scientific issues in ground
In Ghana some informal gold miners operate in the abandoned open pits of large scale mining companies In the case of the Prestea Bondaye mining area most informal gold miners work in the abandoned pits of multinational large scale mining companies Arthur Holmes and Abrefa Busia 2022a Hilson and Yakovleva 2007
The community supplies the labour needed to mine the ore and for hauling it to various points underground where it is hoisted through the shaft including a former CEO and deputy CEO under whose watch the country made incredible gains on the large scale gold mining and exploration fronts 42 The first operation in the program 3 June
The mining industry is a significant asset to the development of countries Ghana Africa s second largest gold producer has benefited from gold mining as the sector generates about 90% of the country s total exports Just like all industries mining is associated with benefits and risks to indigenes and the host environment Small scale miners are mostly accused in

Abstract In Ghana small scale/artisanal gold mining has been on going for more than a century Artisanal mining has been the support for the rural people who more often than
Large scale miners such as Newmont Corp and Gold Fields Ltd have to adhere to strict environmental rules but a thriving artisanal and small scale mining industry is less regulated
There is an extraordinary amount of equipment used in mining ranging from hand tools to large scale machinery We ll focus on the heavy duty machinery here rather than all the mining tools you might find around a site Mining operations need plenty of machinery and vehicles to get the job done and some aren t even for the actual mining
In Ivory Coast Kouame et al 2017 investigated the role of artisanal small scale gold mining ASSGM in the economy and found that int the rural enclave of Ivory Coast ASSGM offers employment opportunities to a sizeable number of people On the basis of this the authors attributed ASSGM activities in the country to factors such as low
They are literally a gold mine of placer deposits There is also an enormous amount of gold bearing mountainous dry placer ground which has remained relatively untouched by large scale gold mining activity because of the scarcity of water required in those locations to support wet recovery methods

that small scale mining poses great risks emanating from inappropriate working tools and this poses great health risk with some causes ranging from inappropriate working equipment and lack of protective clothing Mining Newsweek Magazine 2020 opined that both small scale and large scale mining sectors need funding of over US$7 billion to
Artisanal and small scale mining ASM takes place under extreme conditions with a lack of occupational health and safety As the demand for metals is increasing due in part to their extensive use in green technologies for climate change mitigation the negative environmental and occupational consequences of mining practices are disproportionately felt in
