Artisanal and smallscale gold mining (ASGM) has long been practiced in Nigeria and around the world. Bolstered by historically high gold prices, a lack of viable alternative livelihoods, and a ready – if expensive – supply of mercury, there has been a resurgence of ASGM activities in .
artisanal and smallscale gold mining due to its ease of use, low cost, and abundant supply. Whole ore amalgamation dramatically increases the potential for the mercury that is used to be released to the environment. In some cases, this excess mercury approaches 90% of the total in use. Alternative techniques include many options for concentrating

Artisanal and SmallScale Mining occurs in approximately 80 countries worldwide. There are approximately 100 million artisanal miners globally. Artisanal and smallscale production supply accounts for 80% of global sapphire, 20% of gold mining and up to 20% of diamond mining.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
gold mining operation in Portovelo, Ecuador (Veiga et al., 2009). However, economic and technicalconstraints limit the feasibilityof this technology in the majority of artisanal and smallscale gold mining camps. Mercury retorts, designed to collect mercury emissions during gold processing, have the potential to reduce mercury
