摘　　要：对富硼渣熔态钠化—加压水浸制硼砂、富硼渣碳碱法制硼砂、富硼渣硫酸浸出一步法制硼酸三种工艺进行了研究．结果表明：硼铁矿火法分离得到的富硼渣可以作为制硼砂和硼酸的原料。Three kinds of processes of producing borax and boric acid are study. They are melten boron - rich slag sodium carbonate and water leaching under pressure process, carbonate - alkaline process and sulphuric acid leaching process. The results show that the boron - rich slag obtained from melting ludwigite can be used as the raw material of producing borax and boron acid.
