兴城县位于辽宁省的西南部,山区佔全县面积的50％,拥有比较丰富的矿产资源。矿石性质除南大乡的峡山所产銅矿石为硫化矿外,共它部屬于氧化矿石,矿石含銅品位较低,含杂質較高。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％。根据上述矿石性质及其化学成份,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取的生产流程和操作技术方法及爐子構造等,用各地矿石連續进行了約10次的小型試驗。經試驗的結果証明,在氧化矿石用还原熔煉方法时,由于矿石含銅低(2％),操作技术条件很难控制,因而大部份铁被
Xingcheng County is located in the southwest of Liaoning Province, the mountainous area accounts for 50% of the county, with rich mineral resources. In addition to the ore properties of Xiantao Nanda Township, copper ore sulfide ore, the total part of the ore belongs to the oxide, 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 composition, most of which belong to the oxide ore, and oxide ore is low in copper, it is difficult to take with the blast furnace smelting raw ore into black copper, while the consumption of coke is large, Affect the cost of rising. Therefore, the ore smelting should take the production process and operation of technical methods and furnace structure, with the ore around the continuous about 10 small trials. The experimental results show that, in the reduction ore smelting ore oxidation method, due to low copper ore (2%), the operating conditions are difficult to control, so most of the iron
