Submerge the unrefined gold in a mixture of nitric and hydrochloric acids. This method will dissolve the ore and separate the gold from the impurities, which can later be washed away. The remaining substances will be just water and gold, the latter having a purity level of more than 99.99 percent. Dry this residue until only gold powder remains.
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. The purpose of ...
When the diamond-rich depth is reached, the raw material extracted from the ground is then transported to a special screening plant for further processing.
