Knowledge of and Adherence to the Cyanide Code Among Small
The use of cyanide for gold extraction is a relatively efficient process.1415 While cyanide has been commonly used by large scale gold miners this technology is now popular and is being used in the SGM industry worldwide.81416 This is the case in northern Tanzania including the Lake Victoria basin where cyanide is used to leach the gold
The Borax Method of Gold Extraction for SmallScale Miners
An obvious drawback of this method is the toxicity of mercury.23 The health risk of mercury is well known today in many parts of the world but in remote smallscale mining SSM communities that knowledge is still scarce.4 Gold extraction by amalgamation releases large amounts of mercury into the environment as metal mercury which is later transformed to metholated mercury a powerful
OreCorp continues special mining license engagement in Tanzania
This sentiment was also echoed by the Minister of Minerals in recent press articles in Tanzania. OreCorp will continue to work with all levels of the GoT to deliver the SML and ultimately the first large scale gold mine in Tanzania in over a decade.

Human exposure to mercury due to small scale gold mining in
Abstract. In northern Tanzania large numbers of small scale miners use mercury in the gold extraction process causing contamination of the environment and risks to human health. Human exposure to Hg was assessed in populations in and around small scale gold mining camps by means of human hair and urine surveys.

DOC VAT LEACHING AND ELUTION PLANT GOLD PROCESSING
This Manual will provide a detailed illustration of VATLeaching process as carried by small scale miners in Tanzania which is the second gold extraction process used by small scale miners after amalgamation. The process has eagerly raged all over the country where there are deposits of gold.
Smallscale Mining and Sustainable Development within the
Main countries for smallscale mining activities are Tanzania 550000 miners and Zimbabwe gt 350000 miners where more people are involved in the smallscale rather than in the large and mediumscale mining industry. All country research reports show that smallscale mining is a fast rising sector. The figure

Borax an alternative to mercury for gold extraction by
two smallscale mining communities in Tanzania in May 2009 demonstrated that abandoned tailings from smallscale gold mining may contain a very high gold content with up to 100 ppm of gold. The average gold grade in the ore mined by the smallscale miners is in the order of 3 to 50 ppm. It was
