Scope
Main technical content: There are approximately 55 known zinc minerals in nature, which are divided into sulfide minerals, oxide minerals, and mixed minerals. About one-third of zinc minerals are sulfide minerals or mixed sulfate minerals, of which about 13 zinc minerals are of economic value. Sphalerite (ZnS) is the most zinc-rich mineral, accounting for about 90% of the total zinc production. Other important zinc minerals include fibrolite, anhydrite, rhodochrosite, hydrozincite, red zincite, and silicazincite. The chemical phase analysis method for zinc ores specifies the extraction process and determination methods for zinc content in mineral phases, and clarifies technical indicators such as method detection limits, determination ranges, and precision. It provides important guidance for resource evaluation, mineral exploration, development and utilization, analysis and testing, and beneficiation recovery of zinc ores.
