Abstract

Surfactant application in hydrometallurgical technologies intensifies leaching and electrolysis processes. Lignosulfonates proved their effectiveness in oxidative pressure leaching of zinc sulfide concentrates. Lignosulfonates act as dispersing agents, removing impactful molten sulfur layer from the mineral surface during leaching. However, lignosulfonate application has negative influence on further processes of purification from Cl, Fe, Cu, Ni, and Co. This phenomenon might be related to incorrect reagent dosage. In this paper, the adsorption mechanism was investigated by two different lignosulfonates on surfaces of natural sphalerite and zinc concentrate. Characteristics of adsorption change versus sulfuric acid concentration variation and adsorption isotherm were acquired. It is shown that lignosulfonate adsorption depends significantly on lignosulfonate composition, lignosulfonate and sulfuric acid concentration, and adsorbent nature.
