由于1957年在波兰西南部发现了新的铜矿床,最近15年来铜冶金有了迅速的发展。波兰浮选精矿的特点与世界产出的精矿相比含铜量相似(17～32%),铁和硫则低得多(分别为2～5%,7～10%)。另外的特点是含有有机碳(5～7.5%)和铅(1～3%)。在波兰,生产矿铜的两种方法是鼓风炉法和闪速熔炼法。本文介绍这两种方法的条件和参数以及二者的优缺点,并讨论在铜冶金中采用的新技术和新工艺。
Due to the discovery of a new copper deposit in southwestern Poland in 1957, copper metallurgy has developed rapidly in the last 15 years. Polish flotation concentrates are characterized by similar amounts of copper (17-32%) and iron and sulfur (-2-5%, 7-10%, respectively) compared to the world’s concentrate. Another feature is the organic carbon (5 ~ 7.5%) and lead (1 ~ 3%). In Poland, the two methods of producing copper ore are the blast furnace method and the flash-melting method. This article describes the conditions and parameters of these two methods, as well as their advantages and disadvantages, and discusses the new technologies and processes used in copper metallurgy.
