Graphite Statistics and Information. Statistics and information on the worldwide supply of, demand for, and flow of the mineral commodity graphite. 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.
Ore Veins typically hold less ore than they do before, but due to the style, you'll see a lot more ore around. Surface Ore - Harvest loose rocks for a chance to find ore. 77.0: Removed double metal ore. Enabled Kaolinite spawning and made Graphite more rare. Small surface ore spawning change to make copper more prevalent and tin less so. 78.0
