In this study, it was aimed to recover metallic values by gravity methods from the floor sweeping waste with high gold and silver contents, which are produced as a result of various activities in the jewelry workshops. In addition, the metallic values that remains in the slag phase after thermal process of the floor sweeping wastes were concentrated by centrifugal separators. As a result of gravity separation tests in which the floor sweeping waste subjected to shaking table, MGS (multi gravity separator) and Knelson concentrator, a heavy product (24.2% wt.) was produced with 638 g/t Au and 6227 g/t Ag grades and the metal recovery rates were calculated as 84.4% and 82.2%, respectively. The slag was first ground below 100 μm and then fed to the centrifugal separators in order to obtain fine size gold and silver particles that were trapped in the glassy phase. As a result of enrichment studies with Knelson concentrator, a concentrate (13.8% wt.) was obtained with 30 g/t Au and 52 g/t Ag grades, and the metal recoveries were found as 64.6% and 44.4%, respectively.

Bu çalışmada, kuyumcu atölyelerindeki çeşitli faaliyetler sonucunda açığa çıkan, yüksek altın ve gümüş içeriklerine sahip zemin süpürme artıklarından metalik değerlerin gravite yöntemleri ile geri kazanılması amaçlanmıştır. Ayrıca, bu artıklardaki değerli metalleri kazanmak için uygulanan ısıl işlemler sonucunda oluşan cüruf içerisinde kalan altın ve gümüşü konsantre etmek amacıyla santrifüj ayırıcılar kullanılarak zenginleştirme deneyleri yapılmıştır. Yüksek metal içeriklerine sahip zemin süpürme artığı ile sarsıntılı masa, MGS (multi gravite separator) ve Knelson konsantratörü kullanılarak yapılan zenginleştirme işlemleri sonucunda, ağırlıkça %24,2 oranında bir ağır ürün 638 g/t Au ve 6227 g/t Ag içerikleri ile üretilmiş, metal kazanma verimleri ise sırasıyla %84,4 ve %82,2 olarak bulunmuştur. Cüruf içerisinde ince boyutlarda hapsolmuş altın ve gümüş’ün kazanılması amacıyla malzeme ilk olarak 100 μm altına öğütülmüş ve daha sonra santrifujlü ayırıcılara beslenmiştir. Knelson konsantratörü ile yapılan zenginleştime çalışmalarının sonucunda, ağırlıkça %13,8 oranında bir ağır ürün 30 g/t Au ve 52 g/t Ag içerikleri ile elde edilmiş olup, metal kazanma verimleri sırasıyla % 64,6 ve % 44,4 olarak bulunmuştur.
