Kuvars flotasyonu veriminde tane boyutu etkisinin incelenmesi

Flotasyon, istenen fazları konsantre etmek için belirli bir sıvı üzerinde yüzey özelliklerine göre cevher parçacıklarının ayrılmasıdır. Bu çalışmada, mineralin daha iyi yüzdürme performansını elde etmek için farklı boyutlarda mineraller kullanılmıştır. Partikül büyüklüğünün ayırma verimi üzerindeki etkisinin araştırılması amaçlanmaktadır. Zenginleştirme işleminden önce, mineral yüzeylerinin aktive edilmesi için yüzey işlemleri uygulanmıştır. Flotasyon işlemi, kuvars minerali ve ilgili safsızlıklar arasındaki ayrım işlemini sağlamıştır. Bu çalışmada geleneksel flotasyon kullanılmıştır. X-ışını kırınımı (XRD), Taramalı Elektron Mikroskobu (SEM) ve Enerji Dağılım Spektroskopisi (EDS), faz analizi, yüzey morfolojisi ve kuvars cevherinin yaklaşık bileşimini belirlemek için kullanılmıştır. Daha yüksek miktarda flotasyon ürünü daha ince minerallerle elde edilmiştir. Bu ise, yüzey alanındaki artışla açıklanmaktadır.

The influence of particle size on efficiency of quartz flotation

Flotation is the separation of the particles of the ore according to their surface properties for floating on a given liquid to concentrate the desired phases. In this study, different size of minerals were used to achieve better flotation performance of mineral. It is devoted to investigate the influence of particle size on the separation efficiency. Prior to the beneficiation process, surface treatments were applied for obtaining agitated mineral surfaces. Flotation process provided the separation phenomena between the quartz mineral and associated impurities. In this study conventional flotation was used. X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) were used to perform the phase analysis, surface morphology and approximate composition of the quartz ore. The higher amount of flotation product was achieved with finer mineral. This is explained by the increase in surface area.
