中文摘要: 湿法炼锌低酸浸出改为预中和，可使矾渣含锌由大于7％降至6％以下，根据湿法炼锌工艺及设备实际生产能力，通过冶金计算，提出了预中和技术改造后应作的操作调整，从而指导整个生产流程建立新的平衡，以获得技改预期的经济效益。
中文关键词: 湿法炼锌 低酸浸出 预中和 工艺流程 技术改造
Abstract:Zinc content in jarosite slag can reduced from >7% to<6% after the low acid leaching technic is transformed into pre neutralization According to zinc hydrometrallurgy technology and the equipment capacity, operation adjustment have been put forward after transforming by metallurgy calculation A new balance of the technological process can established directly, and obtain the anticipated econmic profit.
