Copper slag - Wikipedia

Copper slag is mainly used for surface blast-cleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece. Copper slag is just one of many different materials that may be used as abrasive grit. Rate of grit consumption, amount of dust generated, and surface finish quality are some of the variables affected by the choice of grit material.

Copper Slag - an overview ScienceDirect Topics

The replacement of copper slag by copper mine tailings reduced the compressive strength of the alkali-activated cements (Fig. 7.13), depending on the curing temperature. Specimens cured at 60°C and 90°C, containing 50 wt.% copper slag showed comparable strengths to that obtained by samples with 100 wt.% copper slag.

Copper Slag Blast Media Copper Slag price Copper

Copper Slag is often used for steel maintenance and new steel.It is an aggressive abrasive media that is a by-product of copper mining by smelting.. During the process of smelting, all impurities become slag which floats on molten metal. Slag that is reduced in water generates angular granules which are either used in sandblasting or constructing or disposed of as waste.
