    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. The complexity of this processing depends in part on the grade of the ore. Low-grade ore is relatively simple to process while high-grade ore is a more extensive and complicated process.
