chemical method for separating platinum from gold

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.
