摘要
对某磷矿尾矿的物相和化学组成、反应特性及发泡性能进行了研究。结果表明:该尾矿的主要物相为CaMg(CO3 )2、Ca5F(PO4 )3,MgO含量为19. 0%、P2O5 含量为5. 94%;尾矿的反应活性较好,抗阻缓性较差,发泡比较严重,加入消泡剂BMS-1后,发泡明显减弱。
The phase composition and chemical constituent,reaction properties and foaming ability of high-Mg phosphate gangue were studied. The results indicated that the main phase composition of the gangue was CaMg(CO_3)_2 and Ca_5F(PO_4)_3,the content of MgO was 19.0% and P_2O_5 5.94%. The gangue had high reaction activity and low resistance to retardency with highly foaming ability. When BMS-1 added as defoamer,the foaming ability weakened visibly.
