兴城县位于辽宁肖的西南邮,山区佔全县面积的50％,拥有比較丰富的矿产資源。矿石性質除南大乡的峽山所产銅矿石为硫化矿外,其它都屬于氧化矿石,矿石含銅品位较低,含杂质較高。据不完全的分析,含銅0.12～5.84％;鋅0.62～2.69％;二氧化硅25.14～50.52％;硫0.13～9.85％;铁19.49～44.84％;氧化鈣0.16～2.03％。根据上述矿石性質及其化学成防,其中絕大部分属于氧化矿,而氧化矿含銅又低,很难采取用鼓风爐还原熔煉生矿石成黑銅的方法,同时对焦炭的消耗很大,影响成本的升高。因而对此种矿石的熔煉所应采
Xingcheng County, Liaoning Province, located in the southwest of Shaoxing postal, mountain area accounts for 50% of the county, with rich mineral resources. Ore properties In addition to South Daxiang Xiashan produced copper ore sulfide ore, the other belongs to the oxide ore, copper ore grade is lower, with higher impurities. According to incomplete analysis, 0.12 ~ 5.84% copper, 0.62 ~ 2.69% zinc, 25.14 ~ 50.52% silica, 0.13 ~ 9.85% sulfur, 19.49 ~ 44.84% iron and 0.16 ~ 2.03% calcium oxide. According to the nature of the ore and its chemical resistance, most of which belong to the oxide ore, copper oxide and ore is low, it is difficult to take a blast furnace smelting raw ore into black copper, while the consumption of coke is large , Affecting the cost of rising. Therefore, the smelting of such ore should be adopted
