云南省磷矿84％以上是中低品位的高硅矿,特别适于生产黄磷,对此实行投资倾斜政策是正确的。全国黄磷生产能力约13～14万吨,可满足需求,但因国内电力紧张,部分黄磷,磷酸出口,加剧了紧缺状况。预计1990年新增能力13万吨左右。云南在新建扩建小黄磷时应搞好市场调查,不要盲目上马;应首先考虑未并入电网的小水电以确保开工率,建厂规模以不小于2500吨为宜;应尽量深加工以提高价值;要增加电极、焦炭的供
More than 84% of phosphate rock in Yunnan Province is medium and low grade high-silicon ore, especially suitable for the production of yellow phosphorus. It is correct to adopt a tilt investment policy. National phosphorus production capacity of about 130,000 to 140,000 tons to meet the demand, but due to domestic power shortage, some phosphorus, phosphoric acid exports, exacerbating the shortage situation. It is estimated that the new capacity of about 130,000 tons will be added in 1990. Yunnan should do a good market survey when expanding the small yellow phosphorus in the new construction and do not start the project blindly; first, consider the small hydropower that has not been incorporated into the grid to ensure the operating rate and the scale of construction should not be less than 2,500 tons; the deep processing should be conducted to increase the value To increase the electrode, the supply of coke
