graphite were 51,400 t and 129,000 t, respectively. U.S. apparent consumption of natural and synthetic graphite was 60,300 t and 297,000 t, respectively. World production of natural graphite was estimated to be 1.12 million metric tons (Mt) (tables 1, 9). Graphite is one of five forms of crystalline carbon; the

Graphite usually needs beneficiation, meaning varieties of processes to extract the highest purity of the mineral [ 8 ]. In graphite, beneficiation is carried out by handpicking the pieces of gangue (rock) and hand screening the product or by crushing the rock and floating out of the graphite.

In general, precipitated calcium carbonate (PCC) is used as a mineral filler in paper industries; while natural calcite (CaCO 3) ore is also suitable for industrial use if it is a finely ground high-grade material.Naturally, calcite is found in the form of high- or low-grade ores and it is one of the most widely distributed industrial minerals on the earth’s

Flotation is one of the most used methods to upgrade natural graphite resources. However, the efficiency is usually decreased due to the entrainment of undesirable fine gangue minerals. In this work, the impact of different factors such as particle size, pulp density, and flotation reagent on the entrainment of mica and quartz in a flake

Abstract. Herein, synthetic graphite materials with hierarchical pores and large specific surface area were successfully prepared by one-step impregnation with lignite as the carbon source, sulfuric acid (H 2 SO 4) as the oxidant, and phosphoric acid (H 3 PO 4) as the activator.The microstructural characteristics of synthetic graphite were investigated via X
