How can I separate gold mixed with iron ? : askscience

Iron's melting point is around 500degC higher than that of gold (1538 Vs 1064). That can be used to separate them. Thermite reaction is one possible way to melt them. Alternatively, you can react the iron with something external as it is much more reactive or use aqua regia as it readily dissolves noble metals but only dissolves iron sparingly.
