Recovery Of The Recovery Zinc Concentrate In A Weakly Reducing Gas Atmospheric Environment, B T. Berdiyarov, S T. Matkarimov, J B. Ismailov

Technical science and innovation

This article provides information on the formation of substances resulting from the roasting of sulfide-zinc concentrates, which negatively affects the course of subsequent stages. The resulting calcine was sent for reduction roasting in a weakly reducing inert gas atmosphere. Based on this, it can be assumed that the impact on the calcine of "weak" energetic inert gases the reduce minimises or formation of ferrites and zinc silicates. Since the principal primary using agent is gaseous H₂, (hydrogen) in a mixture of gases with a weak reducing environment, all redox reactions occurring in total reduction were studied. The course …
