Sulfate Slag Testing

Sulfate slag is a kind of chemical waste residue, also known as pyrite baking slag or burnt slag. It is the waste residue discharged from the process of making sulfuric acid or sulfurous acid from pyrite. It is a kind of chemical waste residue. Since the slag contains iron, it can be used as a raw material for iron and steel metallurgy. The main chemical component is Fe₂O₃, which generally contains 40%~55% iron, 1.5%~2.0% sulfur, and also contains Cu, Pb, Zn and a small amount of Au and Ag.

Sulfuric acid slag can be used as a raw material for sinter, mainly utilizing the iron content in it to reduce the production cost of sinter raw materials. The sulfuric acid slag is processed to increase its fineness, increase its iron content, and reduce its sulfur content, and can be used as a raw material for pellets. The beneficiation process and beneficiation effect of sulfuric acid slag depend on the physical and chemical properties of sulfuric acid slag. Therefore, the study of sulfuric acid slag is very important.

STEMart provides comprehensive sulfate slag testing services to ensure that the sulfate slag meets the required standards and that it is safe and effective for reuse.
