Research on the Treatment of Lead-Zinc Oxide Ore by CSC
摘要
Abstract
For typical lead-zinc oxide ores,valuable metals in run-of-mine ore mainly exist in carbonate-oxide phases with an extremely high oxidation rate,making separation or enrichment via mineral processing difficult.Based on mineral processing test results and raw material compositional characteristics,a combined pyrometallurgical-hydrometallurgical smelting process is adopted to directly extract metallic zinc and lead from lead-zinc oxide ores for higher metal recovery rates.Therefore,technical research is carried out on direct smelting of run-of-mine ore,where CSC technology is used for ore pretreatment to upgrade lead and zinc grades.Specifically,the process route adopts two-stage fuming and volatilization,namely CSC smelting volatilization followed by CSC fuming volatilization,to produce secondary zinc oxide through pyrometallurgical volatilization and enrichment.The research results verify that treating lead-zinc oxide ores by pyrometallurgical enrichment with the CSC process is feasible.This process benefits zinc hydrometallurgy,reduces the quantity of leaching residue and its corresponding treatment burden,and complies with national cleaner-production requirements and relevant industrial policies.关键词
