This week has been slow around campus, as it has been spring break. Things will pick up soon, however, as I have a busy week scheduled next week.
Sometime soon, the metal casting club (What The Foundry) will be building charcoal furnaces. I believe we have all of the supplies and construction will begin on Thursday.
We are still planning on a field trip to a local concete plant. It has been delayed several times but will happen soon. I will post about it when it happens.
In the mean time, I am in a holding pattern…
Thank you for reading my post.
Back in 2012, we took a trip to Tombstone, AZ, and toured the Good Enough Mine. I will write several blog posts on this trip, but today’s post is about some equipment found near the Good Enough Mine.
Here, we have a belt driven wheel.
I don’t know much about what was attached to it, but I was able to pull the text from the stand, and it reads:
“JOSHUA HENDY MACHINE WORKS S.F. CAL.”
Apparently, the Joshua Hendy Machine Works was a big name by the 1880’s. They specialized in mining equipment, particularly rock crushers, so perhaps this piece was part of a stamp or ball mill of some sort. Their equipment was used in the regrading of Seattle, the building of the Panama Canal, and the construction of the Hoover Dam. The Panama Canal bit was neat, because Joshua Hendy once sailed around Cape Horn to get to San Francisco; his inventions would soon make travel from one ocean to the next easier and safer.
My source is, of course, Wikipedia, and all of the links that I wanted to click on from there are broken.
I finished reading Yellowcake Towns by Michael A. Amundson. The book covered several important uranium mine and mill towns, including Uravan, CO; Moab, UT; Grants, NM, and Jeffrey City, WY.
The book remained objective; it reported facts about each town, rather than spending time on a political soapbox about uranium, mining or company stores. It painted a clear picture of what life was like in each of these towns during their booms and busts.
It told two different tales- one of cities that grew and adapted to changing economies (Moab, Grants) and ones that didn’t (Uravan and Jeffrey City). It also spoke of how the government had a large hand in how mines and mills were controlled and regulated, and the impact of uranium prices as set by the government.
Overall, I was impressed with the depth of research in this book. Each chapter had quite a few sources, as well as tales and quotes by residents in each town.
For anyone interested in the west, the desert, mining history or uranium history, this book is a “must have.”
Thank you for reading my book review.
I posted the first part of this series about nine months ago, and it is about time I followed up with the second and final part.
Back in 2009, an alumni member of the New Mexico Tech Industrial Archeology Club gave us a tour of the Victor and Cripple Creek Gold Mining Company. The first post (Dec 2014) was about the solution extraction plant. This post is about the rock crushing operations.
I like this sequence: this is a haul truck dumping its load into the crusher.
Thank you for reading my post.
We went and saw the remains of the Belmont Mill.
On site, there was some sort of support building. Nobody knows what this building used to be.
Same with the remnants of this wooden structure:
Due to vandalism and age, there were pieces from the mill all over the site:
Inside the mill, however, was a steam-driven wheel that controlled and powered some of the processing.
On the SIA Fall Tour of 2007, we toured what was left of Hamilton City, NV. There wasn’t much left, but there were some building remnants scattered around town.
The Robinson Mine is an open-pit copper mine in northwestern Nevada. As part of the SIA Fall Tour (2007), we were allowed to go into one of the processing facilities, as well as overview the mine from an observation deck.
Inside the processing facility were several large ball mills:
Here are several of the drill bits used in this mine for drilling holes for blasting.
Here is the copper mine pit itself:
