How is gold processed after mining?
Gold extraction refers to the processes required to extract gold from its ores. … Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of low-grade, oxide deposits. Normally, the ore is crushed and agglomerated prior to heap leaching.
How do I know if I found gold?
A) Streak: Gold has a yellow streak. Pyrite has a greenish black streak. … Gold will not scratch a copper surface (Mohs hardness of 3), but pyrite will easily scratch copper. Gold can be scratched by a sharp piece of copper, but copper will scratch very few other materials.
What does fire do to gold?
The dore has to go through a trial by fire at a refinery. In an exciting process called refining, it is re-liquified in a furnace and then heaped with generous amounts of soda ash and borax. This effectively separates the gold from impurities and other metal traces.
