Ekstrakcija bakra iz topioničke šljake kombinovanim postupcima
Copper extraction from smelting slag by combined methods
Abstract
Po svakoj toni proizvedenog bakra u pirometalurškoj proizvodnji nastaje 2,2-3,0 t
šljake, što na svetskom nivou iznosi oko 40 miliona tona šljake godišnje. Ova šljaka u sebi sadrži 0,5-2,1% Cu i tradicionalno se smatrala čvrstim otpadom i odlagala na deponije. Sa padom prosečnog sadržaja bakra u rudi ispod 1% šljaka je postala značajna sekundarna sirovina...
Per each tone of produced copper in the process of pyrometallurgy, there has been
obtained 2,2 – 3,0 t of slag, which is on the world level around 40 million of tones of slag per year. This slag contains 0,5 – 2,1% Cu and it has been considered traditionally the solid waste for years, being dumped on waste dumps. With the decrease of the average copper content in copper ore to under 1%, slag has become a very important secondary raw material...
