云南省硫酸磷肥工业的发展方向

Development trend of Yunnan province's sulphuric acid and phosphorous fertilizer industries

论述近年来云南省硫酸磷肥工业的发展情况及今后的发展方向。到2010年,云南省硫酸产能应控制在12．5 Mt／a左右,约占全国总量的20％;磷肥产能应控制在4．1 Mt／a左右,约占全国总量的25％,其中高浓度磷复肥约占全国总量的35％以上;磷矿产量应控制在20 Mt／a左右,约占全国总量的30％,其中擦洗与浮选磷矿约占70％。

Recent development and future trend of Yunnan province＇s sulphuric acid and phosphate fertilizer industries are discussed. In 2010, Yunnan＇s sulphuric acid capacity will be controlled at about 12. 5 Mr/a, 20% of China＇s total capacity, phosphate fertilizer capacity at 4. 1 Mr/a, 25% of China＇s total capacity, among which high-analysis phosphate ＆ compound fertilizers will be about more than 35% of China＇s total capacity, and phosphate rock output at about 20 Mr/a, around 30% of China＇s total capacity, about 70% of which are scrubbing and flotation concentrats.
