Western Railroad Discussion > Geneva Slag Ballast

The preference of the Rio Grande was for precious minerals slag as being the best for ballast purposes. The two pits used were Midvale from a large slag dump of years of smeltering and the Leadville smelter dump for the same reason. Slag was broken up at the pit by a dozer with a large toothed blade, loaded on the cars, and dumped where needed.

Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
