Refining and Purification: 4. The extracted gold is typically in the form of a concentrated solution or a semi-pure alloy. 5. Refining processes, such as electrolytic refining or Miller process, are used to remove impurities and produce pure gold. 6. The pure gold is melted and cast into bars or other forms for further processing.

The end product, if you do your work properly, can be excellent quality. Be sure to use a trace of sulfuric after you've dissolved the recovered gold. It's not uncommon for gold filled material to have lead used in the assembly process. It's death on gold quality. Sulfuric will insure it's removal through filtration. Harold

Named for the process's inventor, Francis Bowyer Miller, the Miller Process can refine gold up to a purity level of 99.5%. It's ideal for applications that require refining large volumes of gold, and it involves several complex steps. Like most gold refining processes, the Miller Process begins by melting the gold into doré bars. Details
