WHAT IS COPPER SLAG?

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.

(Excerpted from wiseGEEK)

Air-cooled copper slags have a black color and glassy* appearance. As a general rule, the specific gravity will vary with iron content...The unit weight of copper slag is somewhat higher than that of conventional aggregate.

(Excerpted from Publication Number: FHWA-RD-97-148)

* Please note that this glassy appearance results when the slag has been granulated with water. SHARPSHOT® gets its unique qualities by being ambient (air) cooled, and is dull - not glassy.

For ARTICLES on some of the applications for which copper slag is an ideal choice, and for specific details about SHARPSHOT® copper slag, refer to the SHARPSHOT® Technical Data Page in our LIBRARY.
