Abstract

Kuvarsın saflaştırılması, içeriğindeki demirin kimyasal yöntemlerle uzaklaştırılıp öncelikli olarak cam, elektronik, deterjan, seramik, boya, refrakter, metalürji sanayilerinde kullanılabilecek hale getirilmesi açısından önemlidir. Bu çalışmada kuvars cevherlerinden özellikle demir gibi safsızlıkların fiziksel ve kimyasal yöntemler ile uzaklaştırılması ve yüksek saflıkta, nitelikli ürün eldesi laboratuar ölçekte araştırılmıştır. Yüksek alan şiddetli manyetik ayırıcı ile manyetik özelliğe sahip safsızlıklar uzaklaştırılmış, liç testlerinde ise farklı asitlerin performansı, sıcaklık, liç süresi, katı/sıvı oranı, ve asit derişimi gibi parametrelerin demir uzaklaştırma verimine etkisi incelenmiştir. Başlangıçta 400 ppm Fe2O3 içeriğine sahip kuvars örneği ile yapılan deneysel çalışmalar sonucunda Fe2O3 içeriği 37,8 ppm’e düşürülmüş, beyazlık indeksi değeri de 87,43’den 96,81’e yükseltilmiştir.

Removal of Iron from Quartz Ore by Physical Enrichment and Hydrometallurgical Methods

Abstract

Removal of
impurities (iron in particular) from quartz using aqueous chemical processes is
important for its potential use in many industries including detergent,
ceramics, paint, refractory, metallurgy and, in particular, glass and
electronic industries to fulfill the desired requirements by these industries
for high quality quartz as raw material. In this study the removal of
impurities, iron in particular, from the quartz ore by physical and chemical
methods with the aim of producing high quality quartz with desired
specifications were investigated on laboratory scale. Impurities with magnetic
properties were removed by high field intense magnetic separator and in
leaching tests, the influence of various factors including the performance of
acids, reagent type/concentration, temperature, leaching time and solid/liquid
ratio and extent of the removal of iron were studied. After the experimental
studies with quartz sample, Fe₂O₃ content was decreased
to 37,8 ppm from 400 ppm, whiteness index was also increased to 96,81 from
87,43.
