Abstract
Postupak za uklanjanje prevlake od cinka sa čeličnih otpadaka, naznačen time, što se otpaci galvanizovanog čelika prenose kroz sudove (14, 16, 18) u nizu od prvog (14) ka poslednjem sudu (18); što se kroz sudove (14, 16, 18) propušta kaustični rastvor za luženje koji sadrži oksidans i to u nizu, od poslednjeg suda (18) ka prvom (14); što se rastvor za luženje iz prvog suda (14) prebacuje u postrojenje (22) za izolovanje cinka iz rastvora za luženje; što se pomoću elemenata za izolovanje cink izdvaja iz rastvora, čime se rastvor za luženje recikluje; što se rastvor za luženje iz postrojenja (22) za izolovanje cinka vraća u poslednji sud (18); i što se iz poslednjeg suda (18) odnose otpaci iz kojih je uklonjen cink i koji se koriste kao sirovina za punjenje peći za topljenje. Prijava sadrži još 1 nezavisan i 19 zavisnih zahteva.
