Price rise of element sulfur puzzles phosphatic compound fertilizer industry in China;

硫磺涨价困扰磷复肥行业

4 US $/t in 2005,a remarkable price appreciation of element sulfur appears in the international market in the recent years,for a fast increase in imported amount of element sulfur in China,with imported element sulfur amount of 8.

根据近几年我国进口硫磺量的迅速增长,2005年进口量达830万t,占全球硫磺产量的1/5,导致国际硫磺价格猛涨,1997年硫磺到岸价在35~45美元/t,2005年已达94。
