How Gold Is Refined: A Step-By-Step Guide
It's still just raw ore that requires processing before it becomes pure gold. First, the ore is crushed. It then undergoes a series of processes that will vary depending on the different elements and minerals that are mixed in with the gold ore. The purpose of these procedures is to separate the gold from these surrounding elements.
How to Get Gold Out of Quartz (Step-by-Step Guide)

What's the best way to seperate Pyrite from gold?
It takes a long time to dissolve the pyrite that was present and I was also concerned that I might have dissolved some gold into solution because the gold I as trying to seperate was very small. As soon as I put HCl into the material it did turn a dark yellow and that was before I added the Peroxide.
Ausome: Non-Toxic Technology Extracts More Gold From Ore …
Traditionally, once gold ore is mined from the ground, it's crushed to a powder and passed through a series of tanks in a process called leaching. Cyanide is then used to separate the gold from the ore into the leached solution. With the new process, the leaching and recovery process is done with chloride, one of two elements in table salt.
How to Use Bleach on Gold Ore to Remove Gold
Pour the acid-and-bleach mixture into the plastic bowl with the ore grains and stir. Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold inside the ore to …
Refractory Gold Ore Treatment Methods
Where gold is associated with arsenic, antimony, tellurium, and certain other minerals, it is often only partly soluble in cyanide solution. The difficulty is usually more of a physical than a chemical one but special methods of treatment may be required.
