Integration of JKMSI and Oxidation Index to Determine Flotation Behaviour of Sulphide Ores

This paper compares the use of the JKMSI technique and the Oxidation Index methodology to evaluate the change in flotation performance of Cu-Zn complex sulphide ore samples treated with hydrogen peroxide to generate artificially different levels of oxidation and thus ore floatability. The objective of the work is to compare the consistence of the two techniques to measure the variability of ore floatability to get a quick response for the estimation of flotation performance. The results showed that JKMSI can be incorporated in the current Oxidation Index methodology and both techniques have the potential to replace the standard batch flotation tests under certain conditions for geometallurgical ore characterisation programmes. This test uses much less material and much faster than a standard batch scale flotation test. However, both techniques is still have some limitations and further work is required for their improvement.

Sülfürlü Cevherlerde Flotasyon Davranımını Belirlemek İçin JKMSI ve Oksidasyon İndeksinin Entegrasyonu

Bu çalışma, hidrojen peroksitle muamele edilerek yapay olarak farklı derecelerde oksitlenmiş ve dolayısıyla farklı yüzebilirliğe sahip olan Cu-Zn kompleks sülfürlü cevherinin flotasyon performansındaki değişimi değerlendirmek için JKMSI tekniğini ve Oksidasyon İndeksi metodunun kullanımını karşılaştırmaktadır. Çalışmanın amacı, cevher yüzebilirliğindeki değişkenliğin flotasyon performansı üzerindeki etkisinin hızlı bir şekilde tahmin edilebilmesi için iki tekniğin hassasiyetini karşılaştırmaktır. Sonuçlar, JKMSI’nin mevcut Oksidasyon İndeksi metoduna dahil edilebildiğini ve her iki tekniğin de, jeometalurjik cevher karakterizasyon programları için belirli koşullar altında standart flotasyon testlerini değiştirme potansiyeline sahip olduğunu göstermektedir. Bu test, standart bir toplu ölçek flotasyon testinden çok daha az malzeme kullanımı ve çok daha hızlı olma gibi avantajları beraberinde getirmektedir. Bununla birlikte, her iki teknikte de hala bazı sınırlamalar bulunmakta olup bunları geliştirmek için daha fazla çalışma gerekmektedir.
