Bakır izabe curufu flotasyon atığına (CFA) daha önce literatürde ve endüstride hiç uygulanmamış pirit ilaveli asit kavurma işlemi sonrası liç ile baz metallerin ve liç atığı manyetik ayırma ile manyetik ürünlerin kazanımı çalışılmıştır. Çalışmadaki CFA, Türkiye’nin kuzeyinde bulunan sülfürlü bakır madeninin izabesi sırasında açığa çıkan curufun %87 bakır geri kazanılan flotasyonu sonucu kalan fayalit (FeO·SiO2) faz ve bu faza nüfuz etmiş (%0,34) Cu, (%4,16) Zn ve (%0,15) Co baz metallerini içeren çözünmeyen/refrakter camsı/amorf yapıdır. Piritli ve piritsiz asit kavurma işlemlerinin optimizasyonu için sıcaklıklar değiştirilirken (350⁰C -650 °C), asit miktarı 10ml H2SO4 olarak ve kavurma süresi 1s olarak sabit tutulmuştur. Asitsiz yapılan pirit kavurmada fayalit fazının bozunmadığı, 450⁰C’de yapılan kavurma ile 500⁰C, 550⁰C ve 650⁰C sıcaklıklarda elde edilen kalsinlerin X ışını kırınımı desenlerinin benzer olduğu tespit edien CFA için 350⁰C, 400⁰C, 450⁰C sıcaklıklarda 10 ml H2SO4 ve 1:4 pirit/CFA oranında pirit ilavesi yapılarak FeS2 ilaveli asit kavurma işlemi uygulanmıştır. Optimum piritli asit kavurma sıcaklığının tespit edilmesi için liç edilen kalsinlerin liç atıklarının X ışını kırınımı desenleri incelenmiş ve ana fazların manyetit, vustit, hematit ve fayalit olduğu görülmüştür. Liç atıklarının da değerlendirilebilmesi için gerekli olan manyetik ürünlerden vustit ve manyetit fazlarının en fazla görüldüğü koşulun 400⁰C’de yapılan piritli asit kavurmada açığa çıktığı tespit edilmiştir. Manyetik ayrımı gerçekleştirilen liç atığı ile elde edilen manyetik ürünün analizi sonucunda ana fazların manyetit olduğu görülmüştür.

Copper smelter slag flotation tailing’s (SFT) that has not been evaluated yet pyrite additive acid baking phase transformation and water leaching of base metals behaviour and magnetite product by magnetic seperation were investigated. The SFT in the study consists of the residual fayalite (FeO·SiO2) phase from the flotation, with a copper recovery of 87%, of the slag released during the smelting of the copper sulphide mine in northern Turkey, and the non-soluble glassy/amorphous structure containing the 0.34%Cu, 4.16%Zn and 0.15%Co base metals locked and doped to this phase. While the temperatures were changed (350⁰C -650 °C) for the optimization of acid baking processes with and without pyrite, the amount of acid was kept constant as 10ml H2SO4 and the baking time as 1h. It was determined that the fayalite phase did not decompose in acid-free pyrite roasting, and the X-ray diffraction patterns of the calcines obtained at 500⁰C, 550⁰C and 650⁰C temperatures by roasting at 450⁰C were similar. For this reason, an acid baking process with the addition of FeS2 was applied by adding 10 ml H2SO4 and 1:4 pyrite/SFT ratio of pyrite at 350⁰C, 400⁰C, 450⁰C temperatures. In order to determine the optimum pyrite acid baking temperature, the X-ray diffraction patterns of the leachates of the calcines were examined and it was observed that the main phases were magnetite, wustite, hematite and fayalite. It has been determined that the magnetic products required for the beneficiation of leachates, wustite and magnetite phases, are most common in pyrite acid roasting at 400⁰C. As a result of the analysis of the magnetic product obtained with the leachates, which was magnetic seperation, it was seen that the main phases were magnetite.
