Abstract
本发明涉及冶炼技术，是从铜转炉烟灰矿渣中冶炼回收铅的一种新工艺及其成团配方，其特征是：首先在铜转炉烟灰矿渣中加入添加剂后经混辗、压制成团块，再投入冶炼炉中冶炼回收铅；其成团配方是：在每100公斤矿渣中加入2-10公斤石灰、2-10公斤水泥、5-15公斤烟煤。本发明解决了原冶炼技术中炉料透气性差的问题，可提高冶炼炉的生产能力，提高金属回收率，降低能耗。
Description
(一)技术领域：本发明涉及冶炼技术，是一种铜转炉烟灰矿渣成团冶炼铅的工艺方法。
(二)背景技术：在现有技术中，从铜转炉烟灰矿渣中冶炼回收铅的工艺是将烟灰矿渣(水洗渣)直接投入鼓风炉中进行冶炼，由于粉料多，造成炉料透气性差，致使鼓风炉生产能力低，能耗高，同时金属回收率也较低。
(三)发明内容：本发明的目的是要克服上述现有技术中存在的问题，提供一种能耗低、生产力高、回收率高的铜转炉烟灰矿渣成团冶炼铅的工艺方法。
本发明的技术方案特征是：首先在铜转炉烟灰矿渣中加入添加剂后经混辗、压制成团块，再投入冶炼炉中冶炼回收铅。
所述的添加剂为石灰、水泥、烟煤，其配比为：在每100公斤矿渣中加入2-10公斤石灰、2-10公斤水泥、5-15公斤烟煤。
本发明将矿渣成团后再入炉冶炼，有效地解决了炉料透气性差的问题，可提高冶炼炉的生产能力，提高金属回收率，降低能耗。成团添加剂材料易购，成本低，而且对冶炼无不良影响；成团技术简单，操作方便。
(四)具体实施方式：本发明的具体工艺流程是：1.称量：取铜转炉烟灰矿渣(俗称水洗渣)100公斤，石灰2-10公斤，水泥2-10公斤，烟煤5-15公斤；2.混辗：将上述流程1中的原料放入轮辗机中进行混辗；3.压制：将上述流程2中的混合料放入压砖机中压制成团块；4.冶炼：将上述流程3中的成形团块投入鼓风炉中冶炼回收金属铅。
