Enrichment of aladağ (Adana) chromite using taguchi methods

Chromium is the mineral one of which has the largest reserve in Turkey. By applying different beneficiation techniques, chromiumcan be enriched depend on its liberated grain sizes. There several types of beneficiation methods, and the most common beneficiation procedure is the shaking table method from gravity enrichment class. Besides ,magnetic separator is applied to serve for enrichment facilities as well as flotation. Firstly, in prior to determining best kind of method, liberated grain size was settled by performing crushing, grinding and sieve analysis operations. Next best method was selected, and related parameters were detected. For the shaking table method, slope, amplitude of shaking table, velocity and grain size, whereas for flotation, ph, type of collector, grain size and foaming agent were investigated as a parameter. These experiments will be carried out by using taguchi method. Variance analyses(ANOVA) of the variables obtained by using the experiments were performed and tables were prepared. Optimum parameters were determined using the analysis. Shaking table tailings were ground and flotation experiments were carried out with different ph. In these experiments; at first MgO was enrichment with flotation in basic medium after chrom was enrichment with flotation in acidic medium. Keywords : Cromite , Enrichment, Taguchi method, Flotation
