Al_2O_3和二元碱度对炼钢炉渣中磷酸盐富集机理的综合影响
, 2016 以六元Ca O-Si O2-Fe O-P2O5-Fe_2O_3-Al_2O_3炼钢渣系为研究对象,结合热力学计算和实验检测,分析(Al_2O_3)和二元碱度B综合变化对该六元渣系中磷酸盐富集行为的影响.结果表明:炼钢炉渣中生成游离C2S含量对磷酸盐富集相n C2SC3P内的(P2O5)至关重要.该渣系中增加Si O2会降低总的C2S生成量,增加Al_2O_3可促进钙铝黄长石C2AS相生成,降低游离C2S(f-C2S)的量,进而影响磷酸盐的富集.六元Ca O-Si O2-Fe O-P2O5 ...

, 1998 本文的目的是开发出一条简便、高效、节能、洁净地从转炉吹炼渣中提取钴、铜等有价金属的新途径。对转炉渣的工艺矿物学研究发现铜主要以辉铜矿及金属铜形式（二者大约占93%左右）在渣中损失。95%以上的钴在铁橄榄石及磁铁矿集中。浓硫酸熟化方法能很好地分解转炉渣。-200目炉渣加入120%化学计量的H_2SO_4，在75 ℃的最佳条件下熟化1h，Co、Cu的提取率分别大于90%和80%。进一步浸渍陈化30d使Co、Cu的浸出率明显上升，二者均可达到98%以上。研究了熟化后渣的浸出过程。实验对比了从溶液中除去铁的方法。
