As an artisanal miner would it not make sense for me just sink a shaft and hope, because generally, people mining within 200 meter radius of this area are getting very high yields of gold, more than 100g/ton
The urge to make wealth, reduce unemployment, and improve the living conditions of its people pushes the Ethiopian Government to regulate the mining legislation to favour investment in the sector.

The recovery of the precious metals like gold and silver from the cyanide solution is almost universally accomplished by precipitation with zinc, either in the form of fine threads or of dust (the condensed fume recovered in the process of retorting the metal).. The phenomena of precipitation are essentially electrical and may be traced to the action set up by two metals of different
The difference between the copper and zinc protectors (galvanizing) may SEEM to be small but these are two metals are opposites that were commonly used to make electrolitic cells and batteries. In Europe gold leaf has been popular on many fancy jobs but the gold has the highest electromotive potential and iron is slightly low (Au +1.5 to Fe .44).
