    Even once the gold has been extracted from the earth, it’s still in its raw form. 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
