The production & consumption of phosphate fertilizer and sulfuric acid in China in 2004

A review is made to the outputs and structure of various phosphate fertilizers, the output of sulfuric acid and its structure of raw materials, as well as the appearance consumption and the import/export amounts of phosphoric and compound fertilizer, elemental sulfur and sulfuric acid. The total output of phosphate fertilizer in 2004 is 10.174 million tons P_2O_5 with the proportion of 54% in highanalysis phosphate fertilizer. The total output of sulfuric acid in 2004 is 39.95 million tons with the raw material proportions of 35.8% in the production from pyrite and of 40.6% from elemental sulfur. The selfproviding rate of Chinamade phosphate fertilizer is 94.3% with the domestic market share of 87%. In 2005, the outputs of phosphate fertilizer and sulfuric acid is predicted for 11 million tons P_2O_5 and 44 million tons respectively, and meanwhile the import amount of elemental sulfur for 8 million tons.
