业内专家认为 ,我国硫酸产业应稳定硫铁矿制酸。随着冶炼烟气制酸以及硫磺制酸的发展 ,我国硫铁矿制酸的产量在总产量中将下降到 50 %左右 ,到 2 0 0 5年 ,其年产量基本稳定在 1 30 0～1 40 0万ｔ。对现有大、中型硫铁矿制酸能力暂不能盲目改为硫磺制酸 ,主要是采取积极措施解
Industry experts believe that the sulfuric acid industry in China should stabilize pyrite. With the development of smelter flue-gas acid production and sulfuric acid production, the output of pyrite-based sulphuric acid production in China will drop to about 50% in total production. By the year of 2005, the annual output will basically stabilize at 1300-1. 1 40 0 million t. The current large- and medium-sized pyrite-based acid production capacity can not be blindly changed to sulfuric acid production, mainly through active measures.
