Procedures for processing of copper secondary raw materials
Postupci prerade sekundarnih sirovina bakra
Abstract
The technological procedures for copper secondary raw materials processing include two basic stages: pretreatment of the copper waste and its further metallurgical processing. For copper waste pretreatment technology, there are different applied procedures depending on the type of raw material. Scrap of copper cables and wires preparation includes cutting, crushing, air separation and sieving; with the aim of separating the copper from the electrical insulation. The brass slag is grinded, followed by separation metal from oxide components. Chips preparation includes sorting, sieving, degreasing, magnetic separation, and briquetting. The process of electronic scrap preparing is more complex and consists of crushing, sorting, magnetic separation, calcination, combustion, shredding, and sampling. All operations of pretreatment are influencing the quality of metallurgical processing.
Tehnološki postupci prerade sekundarnih sirovina bakra uključuju dva osnovna stupnja: pripremu bakarnih otpadaka i njihovu dalju metaluršku preradu. Za pripremu bakarnih otpadaka koriste se različiti postupci u zavisnosti od vrste i kvaliteta sekundarne sirovine. Priprema bakarnih provodnika obuhvata rezanje, drobljenje, vazdušnu separaciju i prosejavanje sa ciljem odvajanja bakra od izolacije. Masingana šljaka se melje, a potom odvaja metalna od oksidne faze. Pripreme strugotine uključuje sortiranje, prosejavanje, odmašćivanje, magnetnu separaciju i briketiranje. Proces pripreme elektronskog otpada je složeniji i sastoji se od drobljenja, soriranja, magnetne separacije, kalcinacije, sagorevanja, usitnjavanja i uzorkovanja. Sve operacije pripreme utiču na kvalitet metalurške prerade, odnosno na kvalitet proizvoda.
