Bu çalışma kapsamında refrakter olmayan sülfürlü altın-gümüş cevherinin zenginleştirilmesinde çevreye daha dost proseslerden olan flotasyon yönteminin uygulanabilirliği araştırılmıştır. Çanakkale-Serçeler bölgesinden temin edilen 18,85 ppm Au ve 120 ppm Ag içeren numune üzerinde gerçekleştirilen flotasyon çalışmalarına göre, -74 µm tane boyutunda, kaba devrede 1000+1000 g/t Aerophine 3418 A+Aero 208 kullanımı ve 2 kademeli temizleme devresi ile konsantrede %75,8 verim ile 625 ppm Au, %86,5 verim ile 4833 ppm Ag elde edilmiştir. Kaba devrede 1500+1500 g/t Aerophine 3418 A+Aero 208 kullanımı ve 3 kademeli temizleme devresi ile ise konsantrede %69,6 verim ile 1026,5 ppm Au, %80,6 verim ile 8058,1 ppm Ag elde edilmiştir. Bu sonuçlara göre, refrakter olmayan sülfürlü altın-gümüş cevherinden flotasyon yöntemi ile doğrudan izabeye gönderilebilecek nitelikte bir konsantre elde edilebileceği belirlenmiştir. Flotasyon kinetiği ile ilgili çalışmalarda ikinci derece kinetik modelinin bu cevher için uygulanabilir olduğu ve ikinci dereceden flotasyon kinetik sabitleri göz önüne alındığında, gümüşün altına göre 2,5 kat daha fazla flotasyon hızına sahip olduğu sonucuna varılmıştır.
