利用锌浮渣重选尾矿制取活性氧化锌的研究

Research on Preparation of Active Zinc Oxide with the Tailings from Gravity Separation of Zinc Dross

利用锌浮渣重选尾矿,硫酸浸出高温氧化除杂,碳酸氢氨中和沉降、干燥、煅烧,研制生产橡胶制品添加剂碱式碳酸锌与活性氧化锌。

Additives of basic zinc carbonate and active zinc oxide for rubber products were developed and produced with the tailings from gravity separation of zinc dross, by sulfuric acid leaching, impurity removal through high temperature oxidization, neutralization and deposition with ammonium hydrogen carbonate, drying and calcination.
