| Abstract: | A new technique for the preparation of active zinc oxide by precursor calcinating was investigated. Zinc oxide ore was introduced as the raw material for the active precursor preparation adopting a flowsheet including successive processes like acid-leaching, purification, precipitation, filtration, washing, beating and spray drying. The effect of reaction temperature, urea concentration and raw material mixing ratio in the preparation of alkaline zinc carbonate precursor, and the variety and dosage of dispersants added in the drying process, on the precursor particle size distribution, were emphatically studied. |
