一、硼精矿的综合加工工艺简介本文以辽宁宽甸杨木杆硼精矿为代表,对硼精矿的综合加工工艺进行了小型试验。我们所研究的综合法有两层含义,其一是,工艺过程是前部酸法生产硼酸;分离出硼酸后的母液,用碱法生产轻质碳酸镁与化肥,工艺过程酸碱综合。其二是硼精矿中所含硼、镁以及加工过程中所加入的酸根,碱中的阳离子全部综合回收利用,化工厂可实现无三废工艺。
First, the boron concentrate processing technology briefing In this paper, Kuandian Liaoning Kuobu boron concentrate as a representative of the boron concentrate comprehensive processing technology for small-scale experiments. The comprehensive method we studied has two meanings. The first is that the process is the production of boric acid by the front acid method; the mother liquor after the boric acid is separated, the light magnesium carbonate and the chemical fertilizer are produced by the alkaline method, and the acid and alkali synthesis process is comprehensive. The second is the boron concentrate contained in boron concentrate, magnesium and acid added in the process of processing, the cations in the alkali all the comprehensive recycling, the chemical plant can achieve no waste process.
