The effects of the calcine size, leaching temperature, leaching time and solution-solid ration no the leaching rate of the sodium chromate in the chromium calcine are investigated.
结果表明，在试验的浸出条件下，铬焙砂粒度对铬浸出率的影响不显著，铬浸出率随浸出温度升高、液固比增大和浸出时间延长而增加。
The calcine temperature and lasting time were selected as technological parameter during the calcining process.
选取的参数为：煅烧温度和保温时间(煅烧时间)。
