Problems solved by technology

In the fluidized furnace combustion stage of this process, the roasting temperature needs to be controlled within the range of 800-900°C. If the temperature is too high, high-temperature scarring will cause dead furnaces. If the temperature is too low, the slag residual sulfur is high, the yield is low, and the quality of iron concentrate is poor. , and affects steam production
Pyrite is the main raw material for producing s

Abstract

The invention discloses a raw material for preparing sulfuric acid by roasting, and belongs to the sulfuric acid preparation field. The raw material is prepared by mixing and piling up 10-40wt% of titanium dioxide waste residues and 60-90wt% of ore-dressing waste residues, wherein the S content in the raw material is 20-25%, and the moisture of the raw material is less than and equal to 8%; and the ore-dressing waste residues are at least one of copper-dressing waste residues, zinc-dressing waste residues, cobalt-dressing waste residues and titanium-dressing waste residues. The raw material is from industrial wastes and low in cost, resource waste and environmental pollution are avoided, a normal sulfuric acid roasting and preparing process can be met, and qualified fine iron powder is obtained.
