San Jose in Santa Clara County, California — The American West (Pacific Coastal)
Hoeing Table and Cleaning Tank
The two examples above left are “manual” hoeing tables whereupon a worker used a hoe to thoroughly mix mud with lime and allow mercury globules to coalesce and flow out of a spigot into a catching bucket. The cleaning tank, below left, was powered by an electric motor. The motor turned four rubber paddles to mix the mud with water and lime and allow clean mercury to settle to the bottom of the tank, where it was drawn off through a spigot. This type of cleaning tank was able to operate nearly continuously, freeing the worker to perform other duties.
These three tables were used in the Guadalupe mine from the 1940s until the mine closed in the 1970s. The Guadalupe Rubbish Company donated the tables to NAQCPA in 1987.
