Katrenov B.B., Zhumashev K.Zh., Selivanov E.N. Copper sulfate impact on dynamic strength of copper concentrate pellets

Abstract

The article examines the impact of copper sulfate on indicators of dynamic strength of the dried pellets of copper concentrate. The using of copper sulfate as addition to lignosulphonate water solu-tion, which is used as a binder in the granulation of copper concentrate, was suggested. This solution allows to reduce binder solution density from 1.09 to 1.04 g/cm3, and thus, reducing the flow-rate of lignosulfonate on granulation.

Keywords

Copper concentrate pellets, pellets static strength, copper sulfate, lignosulphonate water solution.
