2013 phosphorus and sulfur market seminar held in April this year, the data provided by the China Sulfuric Acid Industry Association ,2013-2015, new sulfuric acid production capacity of a large number of completed and released, more adequate supply of sulfuric acid, the oversupply situation more severe. 

As of the end of 2012, the sulfuric acid production capacity of more than 100 million tons, which sulfuric acid (50%), smelting acid 26%, 23% mineral acid, other acid 1%. 

China Sulfuric Acid Industry Association, who said the massive release of sulfuric acid production, consumption growth is limited, there is no upstream raw materials, the downstream product support sulfuric acid plant will cut, cut. 

Smelting acid ,2011-2012, about 7.5 million tons of plant put into operation. In 2013-2015, there will be about 450 million tons the Fangcheng Jinchuan, Lu Fang, Dongying, Shandong, Anhui Tongling Nonferrous Metals, Fuchun River and Ding Copper plant built, there are some supporting medium-sized lead and zinc smelting acid plant is also under construction in 2015, smelting acid production capacity will increase to more than 13 million tons. 

Sulfuric acid ,2013-2015 there will be about 600 million tons of Hubei Xingfa, Hubei Xin Yang Feng, Guizhou Road, Guizhou Wengfu woven gold, Zhejiang Ningbo Fu device is completed. The mineral acid pyrite limit future capacity growth is limited.
