腐植酸磷矿团块的制造方法

PKODUCTIONMETHOD OF THE LUMPS OF HUMICACID PHOSPHATE ROCK

本文采用腐植酸的盐类作为粘合剂，用于粘结磷矿粉并制成团块，这种团块具有强度好、成本低、Ｐ＿２Ｏ＿５降低在０．３％以下、反应活性好、无污染等优点，可作为生产钙镁磷肥或黄磷的矿石原料，使磷矿粉得到利用，此方法值得推广和应用。

Ground phosphate rock coheres and then is fashioned into lumps withthe salts of humic aeid as adhesive. The lumps made with the method suggested in the paperis of many advantages such as high strenght,low production cost, P_2O_5 content ≤0. 3%,high reactivity and uncontamination etc..It may be used as the raw materials forproducing calcium magnesium phosphate and yellow phosphurus in order that the groundphosphate rock can be fully used.The method is worthwhile to be generalized and cm- ployed.
