Wohlwill process and electricity travels through the electrolyte of chloroauric acid. Gold and other metals are dissolved at the anode, and pure gold (coming through the chloroauric acid by ion transfer) is plated onto the gold cathode. When the anode is dissolved, the cathode is removed and melted or otherwise processed in the manner required for sale or use. The resulting gold is 99.999% pure, and of higher purity than gold produced by the other common refining method, the Miller process, which produces gold of 99.95% purity. For industrial gold production the Wohlwill process is necessary for highest purity gold applications. When
Purity and Danger contexts. What is regarded as dirt in a given society is any matter considered out of place. (Douglas took this lead from William James.) She attempted to clarify the differences between the sacred, the clean and the unclean in different societies and times. But this does not entail judging religions as pessimistic or optimistic in their understanding of purity or dirt—e.g., as dirt-affirming or otherwise. Through a complex and sophisticated reading of ritual, religion, and lifestyle, Douglas challenged Western ideas of pollution, making clear how the context and social history is essential. As an example of this approach, Douglas first
