Mining industry of Ghana
Ghana has produced and exported gold for centuries. In precolonial times, present-day Ghana was one source of the gold that reached Europe via trans-Saharan trade routes. In the fifteenth century, Portuguese sailors tried to locate and to control gold mining from the coast but soon turned to more easily obtained slaves for the Atlantic slave trade. Most gold mining before the mid-nineteenth century was alluvial, wherein miners recovered gold from streams. Modern golGhana is one of the leading producers of gold in Africa and the seventh leading producer in the world. Large commercial companies mine the majority of it using heavy machinery.

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 Tarkwa Mine in Western, was the largest mine in Ghana, producing approximately 13.19 million metric tons per annum (mmtpa) of Run-of-Mine (ROM) and primarily produced gold (521.7 thousand ounces) in 2021. The Tarkwa Mine is owned by Government of Ghana;Gold Fields Ltd, and is due to operate until 2034. The second largest mine with Ghana: Five Largest Mines in 2021 GlobalData

The differing impact of artisanal and industrial mines is related to the process of gold extraction, said study co-author Amanda Payton of East Carolina University. Large-scale industrial mines use heavy machinery to dig deep in a concentrated area.The annual incidence rate of mining-related injury was 289 per 1000 workers. Injuries were mainly caused by machinery/tools 66 (46.1%), followed by slip/falls 46 (32.2%). The major risk factor for injury was underground work (adjusted odds ratio for injury 3.19; 95% CI = 1.42–7.20) compared with surface work.Injury rate and risk factors among small-scale gold miners in Ghana
