Miller process the gold is removed and processed in the manner required for sale or use. The resulting gold is 99.95% pure, but of lower purity than gold produced by the other common refining method, the Wohlwill process, which produces gold to 99.999% purity. The Wohlwill process is commonly used for producing high-purity gold, such as in electronics work and the manufacture of some silicates, where exacting standards of purity are required. When highest purity gold is not required, refiners often utilize the Miller process due to its relative ease, quicker turnaround times, and because it does not tie up the large
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
