A byproduct from the production of rod mills is copper scale. Cal-Chem has a long history of buying this copper scale as well as the associated filter media that is used to separate the byproduct from rest of the mill. Cal-Chem purchases the scale and filter paper separated and also has a program to purchase the scale & paper mixed together.
In addition to smelter feed, this material is used in the production of a specialty oxide product for another industry. Cal-Chem has the ability to purchase and process virtually all copper rod mill byproducts making it a “one-stop” solution for copper rod producers.
