The preparation of ferrous sulfate from pyrite cinder by reduction roasting method 用熟化法從硫鐵礦燒渣中提取鐵
Abstract : zinc calcine contains a small amount of refractory zinc ferrite that can be reduced by reduction roasting 文摘:鋅焙砂含有少量難溶的鐵酸鋅,通過還原焙燒可以降低鐵酸鋅含量。
This paper explores mainly the influence of reduction roasting temperature , time and pulverized coal consumption on content of soluble zinc 本文主要探討還原焙燒溫度、時間和煤粉用量對可溶鋅含量的影響。
