Gold is undoubtedly the most desirable among precious metals. You may
extract gold in a number of ways, after grinding the gold bearing mass so that
maximum gold surface is exposed. To mention few (all under a hood):
a. The aqua regia solution obtained by mixing 3 parts of concentrated HCl with
one part concentrated HNO3
b. The cyanide process using KCN or NaCN solution and air bubbling
c. Same but using (carefully) H2O2 instead of air
d. Iodine solution in KI solution
e. Chlorine obtained by mixing HClO solution with HCl solution
f. Sodium thiosuphate, Na2S2O3, solution, with air bubbling
Stirring and or heating will help in most cases
