摘　　要：用熟化法提取硫铁矿烧渣中的铁 ,熟化温度与硫酸浓度对铁的提取率有显著影响 ,过高的酸浓度不利于铁的提取。为了提高铁的提取率 ,应选择适宜的硫酸浓度和熟化温度。The extracting iron from pyrite cinder by maturation was investigated.The results shows that the maturation temperature and sulfuric acid concentration have obvious effects on iron recovery.An excessive high acid concentration is unfavorable for iron recovery.So a suitable maturation temperature and sulfuric acid concentration should be chosen for raising iron recovery.

关 键 词：熟化法 硫铁矿 矿渣 铁 提取率 熟化温度 硫酸浓度 综合利用
