摘要
讨沦了磷矿中的MgO对化学加工过程的影响.在热法加工中,MgO的影响利多弊少,应重视利用高MgO磷矿发展热法磷肥;在酸法加工中MgO有多种十有害的影响,必须严格控制磷矿中的MgO含量.简要介绍了作者新近开发的化学处理除镁方法的实验结果和应用前景.
: The influences of MgO on various processes for phosphate rock processing are discussed. For thermal processes,MgO
exhibits mainly adventageous effects, and therefore it should be promoted to produce thermal phosphate fertilizers with the
phosphate rock (s) of high MgO content. On acid (wet) processes,MgO has a number of very harmful influences, and so the
MgO content in the phosphate rock used for acid processing has to be limited rigorously. A new process for the removal of MgO
from phosphate rocks developed by the authors and the results are outlined.
