Apr 29, 2014· Enacting small decommissioning groups and contractors to take apart the mining processing facilities and plants; this process will allow the pipelines to be drained, equipment and parts of the mine to be cleaned and sold off, the buildings can be repurposed or demolished, warehouse materials recovered, and wasted disposed of.
The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about percent purity. The Wohlwill process increases purity to about percent by electrolysis.
