Graphite is a form of pure carbon that normally occurs as black crystal flakes and masses. It has important properties, such as chemical inertness, thermal stability, high electrical conductivity, and lubricity (slipperiness) that make it suitable for many industrial applications, including electronics, lubricants, metallurgy, and steelmaking.
water and graphite ore processing through the mine life. The Chilalo Graphite Project is located within the Mozambique Belt of SE Tanzania (Figure 1), which is host to some of the world’s highest grade and coarse flake graphite deposits, including the Chilalo Graphite Project (Graphex Mining), Balama Project
While other materials include soya beans oil, kerosene and graphite ore. METHOD A sample of ground graphite was weighed up to 300g using the triple beam balance. Distilled water of up to 1000cm3 was measured and mixed with the graphite ore, poured into the flotation cell and agitated for 2 minutes at the speed of 1500rpm.
As the high value and the scarcity of large-flake graphite ore resources, it is in the best interest to maximize the amount of large flakes and minimize any processing that will reduce flake sizes.
PROCESSINGThe processing method for Malawi graphite will be through flotation. It is expected that the weathered ore has larger quantities of chlorite, sericite, smectite and kaolin. Iron oxides are also in abundance. The unweathered ore is composed largely of feldspar, quartz and micas.
The ore of vein graphite exhibits high crystallinity (basal plane separation of 0.335 nm) and the highest purity, of ca. 90e99 wt% of carbon content, flake graphite has carbon content ranging from
Graphite chemical purification of the most mature process is the use of caustic and graphite melting at 700 ℃, after washing to neutral, plus hydrochloric acid treatment, washing, so that graphite carbon content reach 98% to 99%. Some manufacturers use hydrofluoric acid to produce high-purity graphite. There are many graphite ore processing

Weber (1993) has also demonstrated that the chromite ore cannot be reduced by CO gas alone, in the absence of carbon. The ore can be reduced by carbon, but the reaction may proceed through two steps: FeCrO 4 + 4C Æ Fe + 2Cr + 4 CO 2 and C + CO 2 Æ 2CO.

Graphite Statistics and Information. Graphite is a soft, crystalline form of carbon. Other forms are diamond and fullerenes ("buckyballs"). It is gray to black, opaque, and has a metallic luster. It is flexible but not elastic. Graphite occurs naturally in metamorphic rocks such as marble, schist, and gneiss.
