Abstract
Flotasyon tekniği tüm dünyada yaygın olarak kullanılan zenginleştirme yöntemlerinin başında
gelmektedir. Talkın sahip olduğu doğal hidrofobik yapısı sayesinde, grafit, taş kömürü, molibden
ve kükürt gibi ender mineraller kollektör adı verilen kimyasal toplayıcı kullanmaksızın yüzebildiği
bilinmektedir. Flotasyon yönteminde, kollektör ve köpürtücü adı verilen pahalı kimyasalların ve
suyun niteliği büyük öneme sahiptir. Bu nedenle flotasyonda kullanılan kimyasal sarfiyatının
azaltılması veya hiç kullanılmaması flotasyon tesislerinin işletim masraflarını büyük oranda
düşürebilir. Çözünmüş hava flotasyonu (ÇHF) tekniğinin ince tane boyutundaki (-38 μm)
malzemelere de uygulanabilmesi ince boyutlu artıkların değerlendirilmesine olanak verebilir.
Ayrıca günümüzde hızla tükenen ve kirlenen su kaynakları göz önünde bulundurulduğunda
flotasyon tesislerinde suyun çevrimi ve tuz içeriği yüksek kuyu suyu kullanımı zorunluluğu ortaya
çıkmaktadır. Bu çalışmada doğal hidrofobik minerallerden olan ince boyutlu talkın kollektör ve
köpürtücü kullanmaksızın tuzlu sular (NaCl, ve MgCl2) içerisinde yüzebilirliği araştırılmıştır. Tuzlu
sular varlığında laboratuvar ölçekli ÇHF ekipmanıyla yapılan flotasyon deneyleri sonucunda talkın
flotasyon veriminde %14’lük artış elde edilmiş olup sonuçlar ışığında Na+ ve Mg+2 iyonlarının talk
flotasyonuna etkisi ortaya konmuştur.
