前言为了处理澳北区沃里戈(Warrego)的佩科矿业公司铜精矿,决定建设一座冶炼厂,否则精矿运往海外市场出售增加运费和关税。同时铜精矿中的铋不能计价,而且铋的含量还在增加。期望沃里戈选矿厂生产的铜精矿含铋控制在2％以内,因此,考虑采用传统炼钢技术不能生产市场畅销的粗铜。决定用闪速炉配以有隋性气体吹炼期的顶吹转炉(TBRC)工艺
INTRODUCTION In order to process the copper concentrate at Peco Mining Company in Warrego, North Australia, a smelter was decided to be built or the concentrate will be sold overseas to increase shipping costs and tariffs. Bismuth in copper concentrate can not be priced at the same time, and the content of bismuth is still increasing. It is expected that the bismuth concentrate in the copper concentrates produced at the Warrigo concentrator will be controlled within 2%. Therefore, considering the traditional steel-making technology, it is impossible to produce the best-selling blister copper in the market. Decided to use flash furnace with inert gas blowing top blowing converter (TBRC) process
