The relation. between the con- verting rateof chromium and roasting temperature , the amount of soda , the amount of back slag - copper oxide are also studied.
研究了铬转化率与焙烧温度、配碱量、返渣氧化铜的量等条件的关系。

Pyrite roasting process was studied by using TG-DTA thermal analysis. The effects of sample size, heating rate and roasting atmosphere on the roasting process were discussed.
用TG - DTA热分析法研究黄铁矿在不同粒度和不同升温速率及不同气氛中的焙烧过程。
