山西晋城县北石店公社革委会,用毛主席哲学思想指导科学实验,利用晋城煤矿的煤矸石成功地制取了氨水,为煤矸石综合利用闯出了一条新路。该地煤矸石含有一定数量的铵盐及有机氮化物,燃烧后分解成氨,通过铁管,经水冷却即得氨水。氨水含氮量约百分之五左右,可作速效化肥。自去年十二月份以来,该公社大搞 The Revolutionary Committee of Beishidian Commune of Shanxi Jincheng County used the Chairman Mao’s philosophical thinking to guide scientific experiments and successfully used ammonia from Jincheng coal mine to produce ammonia. A new road has been created for the comprehensive utilization of coal gangue.

The nitrogen content of ammonia is about 5 percent, which can be used as quick-acting fertilizer. Since December last year, the commune has been engaged in
