摘要

本文以高磷鲕状赤铁矿为原料,通过探讨焙烧条件、酸浸条件以及水解沉淀方法、煅烧条件等对制备氧化铁红的影响,推荐湿法制备氧化铁红的生产工艺。试验表明,高磷鲕状赤铁矿通过还原焙烧得到金属Fe精矿更容易酸浸,得到的FeSO_4溶液经过除杂、水解沉淀、洗涤、干燥煅烧等工序后,可得到纯度为99.5%的氧化铁红,达到开发利用高磷鲕状赤铁矿的目的。
        In the paper, by using the high phosphorus oolitic hematite as the raw materials, the influence of roasting, acid leaching condition, hydrolysis precipitation method and calcination condition one the preparation of iron oxide red were discussed, recommending wet production technology for preparation of iron oxide red. The results showed that the Fe concentrate was more easily obtained by reductive roasting of the high phosphorus oolitic hematite. The produced concentration can obtain the purity of 99.5% of iron oxide red by the process of removing impurity, hydrolysis precipitation, washing, drying and calcining, achieving the goal of development and utilization of high phosphorus oolitic hematite.
