In this study, pre-enrichment of a typical lead-zinc leaching plant solid tailings were investigated. After the leaching process, due to the decrease in the grain size of the residual minerals (filter cake) and the deterioration of the mineral crystal structures, a concentrate with high recovery for lead (Pb) and zinc (Zn) could not be obtained with mineral enrichment methods / machines such as flotation, multi-gravity separator (MGS), shaking table and Knelson separator. It was determined that the Pb and Zn minerals were concentrated in very fine fractions (<75 µm) by chemical analyzes according to grain size fraction. Thus, it was decided to perform the enrichment method according to the grain size classification and 150 micron sieve and hydrocyclone were used respectively in the enrichment process. After the sieving, a concentration (51.35% by weight) was obtained with 86.64% Pb and 64.84% Zn recoveries. The enrichment process was continued with a series of hydrocyclone experiments using the obtained pre-concentrate. The highest recoveries for Pb and Zn with hydrocyclone experiments were obtained as 71.18% and 52.6%, respectively. As a result, it was found appropriate to disperse the agglomerated coarse sized grains using a roller and/or bar mill prior to sieving to obtain a concentrate with higher recovery.

Bu çalışmada, tipik bir kurşun-çinko liç tesisi katı atıklarının ön zenginleştirilmesi araştırılmıştır. Liç işlemi sonrasında kalan minerallerin (filtre keki) tane boyutunun büyük oranda düşmesi ve mineral kristal yapılarının bozulması sebebi ile flotasyon, multi gravite separatör (MGS), sallantılı masa ve Knelson separatörü gibi cevher zenginleştirme yöntem/makineleri ile kurşun (Pb) ve çinko (Zn) için verimli bir konsantre elde edilememiştir. Tane boyutu faksiyonuna göre yapılan kimyasal analizlerde Pb ve Zn minerallerinin çok ince boyuttaki fraksiyonlarda (<75 µm) yoğunlaştığı tespit edildi. Böylece, zenginleştirme metodunun tane boyutuna göre sınıflandırma ile yapılmasına karar verilmiş ve zenginleştirme prosesinde sırasıyla 150 mikronluk elek ve hidrosiklon kullanılmıştır. Eleme sonrasında % 86,64 Pb ve % 64,84 Zn verimleri ile konsantre (ağırlıkça % 51,35) ürün elde edilmiş ve bu konsantre kullanılarak bir dizi hidrosiklon deneyleri ile zenginleştirme prosesine devam edilmiştir. Hidrosiklon deneyleri ile Pb ve Zn için en yüksek verim sırasıyla % 71,18 ve % 52,6 olarak elde edilmiştir. Sonuç olarak, daha yüksek verimli konsantre ürün elde etmek için aglomera olmuş iri boyutlu tanelerin eleme öncesinde merdaneli ve/veya çubuklu değirmen kullanarak dağıtılması uygun görülmüştür.
