How were the ores mined in Park City turned into silver, lead or gold bars? Why were they crushed and concentrated? Mining Engineer Donovan Symonds offers practical demonstrations and slides to explain the processes involved in sorting the ores into concentrates and waste rock.
Early prospectors used simple sorting methods compared to the complex processes used in the Silver King and California Comstock Mills. The refining process was predominantly conducted in large furnaces in the Salt Lake Valley and a brief description of what was involved is included.
Donovan Symonds is a long time resident of Park City, moving here in 1977. He is a retired consulting mining engineer specializing in mineral processing and holds a degree in mining engineering from Newcastle University in England and a PhD in gravity concentration from Nottingham University. He has enjoyed being a Park City Museum docent for about 8 years.
