1.16: Methods for Separating Mixtures
Separation of Mixtures Not everyone is out searching for gold (and not many of those searchers is going to get much gold, either). In a chemical reaction, it is important to isolate the component (s) of interest from all the other materials so they can be further characterized. Studies of biochemical systems, environmental analysis, pharmaceutical research – these and many other areas of

2010722· Haven''t done anything chemical yet to them. I sat down, make some research on common copper and gold thickness on PCBs, played with data on Excel and find that Molality-wise there''s way too much copper against gold in most configuration of copper/gold thickness. I find that seperating copper from gold using HNO3 is quite costly.

How to segregate gold ore from copper ore
3. Chemical Separation Processes Flotation: This is the most widely used technique for separating gold from copper ores. The ground ore is mixed with water and special chemicals, which result in the preferential attachment of gold and copper particles to air bubbles. These air bubbles rise to the surface, forming a froth that is then skimmed off.
