Artisanal and SmallScale Gold Mining Without Mercury
In many countries, elemental mercury is used in artisanal and smallscale gold mining. Mercury is mixed with goldcontaining materials, forming a mercurygold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury
PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.

Smelting and Roasting Ores to recover gold, silver and
The product of melted sulfides is called a matte, and is highly corrosive liquid. Converting that molten sulfide matte to metal is called smelting. Small scale smelting can be done in a crucible – in fact that is what a fire assay is. When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix.
