配料是灵活的,也是有規律可以计算的。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％才能作配料計算。对铜矿石的分析只分析銅,不分析其他元素,要作配料計算是不可能的。化学分析当中需包括下面七种元素的分析:銅、硫、氧化鈣氧化鎂、二氧化硅、二氧化鋁氧化鉄等。作配料計算之前,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、燃料消耗及铜在渣中的損失。还原熔煉中,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 other oxide 鉄. 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. In smelting reduction, the variation range of slag is as follows:
