i test for gold in a solution with stanous chloride crystals-----i put one or two crystals into a becker,and spread over a small quantity of a solution that i suspect,that contains gold---if the solutions darkens ,indicates gold--the darker the solution,more the concentration of gold in it----this dark solutions, of what i think is coloidal gold, i put in a stock pot----now i acumulated 2liters of this solution which i think is coloidal gold-----How to get back the gold from this coloidal solution? i think ,that it is not much--but is still gold(a few grams) -----------thanks for the help------
