How do i separate gold from sulphides without using chemicals or dieing from sulpheric acid?
My freind has a large supply of microscopic gold particles, however they need to be separated from sulphides. there is a high concentration of gold in this solution, and millions of dollars could be made. however, heating the sulphides will make sulpheric acid, which burns away your lungs (also used in chemical warfare). chemicals currently used for the process of separating sulphides from gold are very toxic, and also expensive. the chemical process is very inefficient too. i am looking for a way to separate sulphides from gold without using (toxic, dangerous, expensive, rare) chemicals.
