【摘要】：采用工業(yè)鹽酸分解高鎂磷尾礦并制備硫酸鎂產(chǎn)品,對(duì)酸解條件、酸化條件及濃縮比例進(jìn)行試驗(yàn)研究。結(jié)果表明,工業(yè)鹽酸與磷尾礦質(zhì)量比2.25、反應(yīng)時(shí)間20 min、反應(yīng)溫度60℃時(shí),分解率最高;當(dāng)濃硫酸質(zhì)量分?jǐn)?shù)98%時(shí),除鈣效果更佳;將酸化濾液進(jìn)行1次濃縮比例0.65、2次濃縮比例0.20,得到七水硫酸鎂產(chǎn)品,可達(dá)到國(guó)家行業(yè)標(biāo)準(zhǔn)一等品要求。該工藝可避免環(huán)境污染,節(jié)約資源,具有潛在的經(jīng)濟(jì)價(jià)值。
[Abstract]:Industrial hydrochloric acid was used to decompose high magnesium phosphate tailings and to prepare magnesium sulfate products. The acid hydrolysis conditions, acidification conditions and concentration ratio were studied. The results showed that the mass ratio of industrial hydrochloric acid to phosphorus tailings was 2.25, the reaction time was 20 min, and the reaction temperature was 60 鈩，
