If you're introducing a new process at your workplace or documenting an existing one, a process map template can help. A process flow chart template uses symbols and diagrams to depict complex processes from start to finish. Just enter your process data to the Excel flowchart template, then export to automatically create the shapes and connectors that visually tell the story.
REFINEIT-EK will refine almost any type of gold except computer boards. Gold-filled items must be mixed with solid karat gold before refining. REFINEIT will provide the best gold return with the lowest consumption of chemicals, and will reduce the entire process to a single, simple step, minimizing the need for human involvement.

Mar 04, 2020· Other less common methods are cupellation, inquartation and parting, fizzer cell, aqua regia, and the pyrometallurgical process. According to the World Gold Council, the Miller process uses gaseous chlorine to extract impurities when gold is at its melting point. Impurities separate into a layer on the surface of the molten purified gold.
