Abstract
In this study, the enrichment of the Kutahya Altintas graphite ore by flotation was carried out. Flotation parameters such as particle size, pH, type and dosage of collector, and frother dosage, dosage of depressant, as well as solid ratio were investigated. As a result, a clean graphite concentrate of 77.80% total carbon content was obtained with 46.68% total carbon recovery.
Highlights
Graphite is a crystalline, polymorphic form of elementary carbon [1]
4.1.3 Effect of depressant dosage To determine the effect of depressant dosage, several flotation tests were performed with different dosages of sodium silicate varying from 500 g/t to 2500 g/t
The optimum particle size was determined as 0.106 mm
Summary
Polymorphic form of elementary carbon [1]. Depending upon the mode of occurrence and origin, graphite is graded in to three forms: flake-found in metamorphosed rocks as vein deposit, crystalline (lumpy)-found as fissure filled veins, crypto crystalline (amorphous) form in metamorphosed coal beds [4, 5]. Graphite generally occurs as a result of metamorphism of organic matter in sediments. Flake graphite is assumed to be derived from finegrained sediments rich in the organic matter. Carbonaceous material converts to amorphous graphite [3, 6]. The specific properties of graphite result in its increasing importance in the refractory industry [1, 10]
