Background Information for Robert Phillips, lecturer on the Nordberg Steam Stamp, September 10, 2019

The Nordberg Stamp located on the grounds of WMMI is one of two remaining examples of this type of vintage rock crushing machine that was used predominately in the copper mining belt in Michigan’s Upper Peninsula.

Mr. Phillips is a graduate of Michigan Technological University also located in the same historic mining region. After attaining an engineering degree in 1968, he was employed for 45 years in mining or mining-related activities. During his university years, the copper mining industry was active in Michigan. This exposure instilled an intense interest in mining and metallurgy and, in particular, the historically important and textured history of Michigan copper mining.

Mr. Phillips worked as a student engineer during the summer of 1967 in the last operating stamp mill in the US and witnessed the operation of the Nordberg stamps and associated copper concentrating equipment.

The stamps fell silent forever fifty years ago this year.  Their activity, sounds, and smells now exists only in the memory of those that were there.
