我院在山西五台和北京郊区怀采县試驗一种簡易的冰銅处理方法——焙燒——反应熔煉法。这种方法在技水上很簡便,不需要动力設备,适宜于中小型的土法煉铜厂处理冰铜。現將这一方法的技术操作实踐介紹如下。供各地参考。生产流程在这几次生产試驗中,我們將貧冰铜先經一次焙燒,放在鼓风爐內进行富集熔煉,然后以其2/3总量富冰銅放在燒結鍋內进行死燒,此后即与小于1/3总量未焙燒的富冰銅放在坩堝爐进行反应熔煉。如果鼓风爐产出的冰銅品位很高,达60％以上,那么这种冰銅可不必富集,而直接进行死燒,然后按同样步驟进行反应熔煉。这一方法的生产流程如左图。
Our hospital in Wutai Shanxi and Beijing suburbs Huai mining a simple method of matte - roasting - reaction melting method. This method is very simple in technical water, does not require power equipment, suitable for small and medium-sized indigenous copper smelting process. The technical operation of this method is now described below. For reference. Production process In these several production tests, we will be first impoverished copper matte, placed in the blast furnace enrichment melting, and then its 2/3 total amount of iced cupper placed in the sintering pot to death , And then with less than 1/3 of the total amount of unfrozen ice-rich copper in the crucible furnace for reaction smelting. If the blast furnace output of matte grade is high, reaching more than 60%, then this matte does not have to be enriched, and directly burned, and then the same steps for reaction smelting. The production process of this method is shown on the left.
