Small scale mining contributes about 2 to 5 tonnes of gold per year in the above table. Although the amount of gold produced by the Small Scale Sector is much smaller than the bigger mines, it gives very large economic benefits and support system to over ten thousand miners
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

The more gold, the faster the process. This is because it is the friction of gold against gold which facilitates the cleaning process. Once the gold is glittery, rinse the soapy water out of the jar, pour the gold into a small (metal) finishing pan, and heat it up (outside and down wind) until the gold takes on a deep, natural, shiny luster.

This is handy when processing silver containing minerals to convert them to silver metal. The addition of scrap iron to smelt mixes is a useful technique to smallscale operators experimenting with smelting techniques on goldsilver ores. It could also be used with small lots of sulfide concentrates.
For most smallscale gold prospectors, crushing ore to determine the amount of free gold is the best method to determine gold content within an ore sample. Free gold can then be collected using traditional gravity based methods, which do not require the same level of permitting as the chemical methods used by commercial gold mines.

gold, referred to as flour, flood, or colloidal gold, is lost in processing. Early miners recovered no more than 60% of assayed gold values, and as late as 1945 recovery of free gold averaged only 7075% (Spiller, 1983). Moreover, it is likely that most remaining placer deposits have a higher percentage
