芬兰奥托昆普公司研制出一种能耗低 ,污染小的“水铜”湿法冶炼新技术。先将铜精矿石冶炼成铜粉 ,再将铜粉溶化直接浇铸成铜棒 ,也可以制成其他铜产品。这种新技术 ,不仅能耗低 ,而且冶炼过程中不会产生硫酸 ,对环境污染小 ,可以较好地回收铜精矿石中含有的金和银。为从各种铜 Finland Outokumpu company developed a low energy consumption, pollution, small “water copper” smelting new technology. First smelting copper concentrate into copper powder, and then pouring the copper powder directly into a copper rod can also be made into other copper products. This new technology not only low energy consumption, but also does not produce sulfuric acid during the smelting process, the environmental pollution is small, can better recover gold and silver contained in copper concentrate ore. For all kinds of copper
