湖南省花垣锰矿富锰降磷采样工作,根据长沙黑色冶金矿山设计研究院设计,分别采取南、北矿段两个矿样,1986年11月17日通过设计审查,至1988年11月,历时两年,在设计、研究、生产部门密切配合下,采出南段样126t,锰品位18.41％,较设计品位18.34％超差0.07％≤±1％,磷品位0.2％,较设计磷品位0.181％超差0.019％<±0.02％,1987年9月已运到各试验单位;采出北段样53(?),锰品位18.25％,较设计品位18.48％超差0.023％<±1％,磷品位0.282％,较设计磷品位0.286％超差0.004％<±0.02％,此样也已运至各试验单位。根
According to the design of Changsha Black Metallurgical Mine Design and Research Institute, two ore samples from the South and North ore mines were taken respectively. The design review was passed on November 17, 1986 and lasted until November 1988 In the past two years, with the close cooperation of design, research and production departments, the southern segment of 126 t was taken and its manganese grade was 18.41%, which was 0.07% less than ± 1% of the designed grade and ± 0.2% of the designed grade. The phosphorus grade was 0.2% % Exceeded ± 0.019% <± 0.02%, which was transported to each experimental unit in September 1987; 53 (?) Northern section was sampled with manganese grade of 18.25%, exceeding the design grade of 18.48% by 0.023% <± 1% 0.282% phosphorus grade, 0.286% better than the design grade tolerance 0.004% <± 0.02%, this has also been shipped to each test unit. root
