摘要
用物质自由焓函数法,计算了硫化铜精矿进行硫酸化焙烧时主要反应的标准自由焓△G_T^0,作出了△G_T^0-T图和优势区图(1gPso_2-1gPo_2关系图),较为简单,明了、直观地从理论上确定了硫化铜精矿硫酸化焙烧时所应控制的炉温和气氛,为工业生产提供了理论上的依据。
Free-enthalpy function of substances mothods is used to calculate standard flee enthalpies of main chemical reaction in the process of sulphatizing roasting, and the △ G_T^0-T diagram and 1gPso_2-1gPo_2 diagrams are drawn. The furance temperature and the gaseous phase composition, which should be controlled in the process, are determined simply, clearly and directly. This provieds theoretical basis for industrial production.
