前言;近几年来国外湿法冶金发展概貌湿冶发展史可追溯到1752年西班牙 Rio-Tinto 硫化铜矿堆浸—置换海绵铜。但早期湿冶大规模生产铜的主要对象是氧化铜矿,因它难选又易溶于稀硫酸中,例如智利 Chuquicamata 铜矿就是盐基性硫酸铜,每天用稀硫酸渗浸40,000吨矿石,富铜液电 Foreword; Overview of Hydrometallurgy Development in Foreign Countries in Recent Years The history of wet-metallurgy can be traced back to the heap-displacement sponge copper of Rio-Tinto copper sulfide ores in Spain in 1752. But the early wet metallurgy large-scale production of copper is the main target of copper oxide, because it is refractory and easily soluble in dilute sulfuric acid, for example, Chuquicamata copper mine in Chile is salt-based copper sulfate per day with dilute sulfuric acid infiltration of 40,000 tons of ore, Copper-rich liquid electricity
