Abstract

In this study, the detailed mineralogy and beneficiation possibilities of a lateritic nickel ore from Mihalıççık-Eskişehir region was investigated. Quantitative mineralogical analysis of the ore was performed using MLA (Mineral Liberation Analyzer); ernienickelite and pimellite minerals were determined as nickel bearing minerals. Heavy liquid test was performed to determine the amenability of the ore to gravity separation. In the scope of beneficiation studies, optical sorting, dry and wet magnetic separation and microwave heating were applied. As a result of the tests, there was no significant improvement in nickel grade. Only a slight decrease in the arsenic grade of the microwave-heated ore was observed. The presence of ernienickelite locked with very fine silicates (usually clays and Si oxides), supports the fact that the ore cannot be beneficiated easily by physical beneficiation methods.

Özet

Bu çalışmada, Mihalıççık-Eskişehir bölgesine ait lateritik bir nikel cevherinin detaylı mineralojisi ve zenginleştirme olasılıkları araştırılmıştır. Cevherin kantitatif mineralojik analizi MLA (Mineral Liberation Analyzer) kullanılarak yapılmış; ernienikelit ve pimelit mineralleri nikel taşıyıcı mineraller olarak belirlenmiştir. Cevherin yerçekimi ile zenginleştirmeye uygunluğunu belirlemek için ağır sıvı testi yapılmıştır. Zenginleştirme çalışmaları kapsamında optik ayırma, kuru ve yaş manyetik ayırma ve mikrodalga ile ısıtma yöntemleri uygulanmıştır. Testler sonucunda nikel tenöründe kayda değer bir iyileşme gerçekleşmemiştir. Yalnızca mikrodalga ile ısıtılan cevherin arsenik tenöründe bir miktar düşüş gözlenmiştir. Ernienikelitlerin çok ince silikatlar (genellikle kil ve Si oksitler) ile bağlı formda bulunması, fiziksel zenginleştirme yöntemleri ile cevherin kolaylıkla zenginleştirilemeyeceğini desteklemektedir.
