Study on the Preparation of ZnFeO4 by Roasting Zinc-Containing Gossan Ore

Gossan ore is typically abandoned after mining, which not only increases mining production costs but also wastes mineral resources, and its long-term accumulation can easily lead to environmental pollution hazards. Therefore, this paper takes zinc-containing gossan as the research object and, based on high content of zinc iron minerals in ore, study conducts a roasting experiment prepare ZnFeO4. X-ray diffraction used characterize analyze ZnFeO4 sample prepared by ore. The experimental results indicate that controlling particle size roasted −0.074 mm effectively remove impurities facilitate reaction. influence temperature time formation remarkable. conditions for maximize are follows: sample, reaction zinc/iron molar ratio 1:2, mechanical activation 120 min, 1050 °C, min. These findings provide new ideas utilization lay theoretical foundation efficient development difficult-to-select
