配料是灵活的,也是有規律可以計算的。配料首先注重矿石的化学分析。分析元素的总和必須达到90％才能作配料计算。对銅矿石的分析只分析銅,不分析其他元素,要作配料计算是不可能的。化学分析当中需包括下面七种元素的分析:銅、硫、氧化鈣氧化镁、二氧化硅、二氧化鋁氧化铁等。作配料计算之前,必須根据矿石分析选擇接近而适当的渣型,这样才能減少溶剂用量、燃料消耗及銅在渣中的损失。还原熔煉小,渣的变化范圍如下:
Ingredients are flexible and regularly calculated. Ingredients first focus on the chemical analysis of ore. The sum of the analysis elements must reach 90% for ingredient calculation. Analysis of copper ore only analyze copper, do not analyze other elements, to make ingredients calculation is impossible. Chemical analysis should include the following seven elements of the analysis: copper, sulfur, calcium oxide and magnesium oxide, silica, alumina and iron oxide. For ingredient calculations, the slag type must be chosen to be close and appropriate based on the ore analysis, in order to reduce the amount of solvent used, the fuel consumption and the loss of copper in the slag. Smelting small reduction, the scope of the slag changes as follows:
