Graphite purification
WebOct 1, 2002 · After roasting with NaOH at 250 °C, and followed by water washing and H 2 SO 4 leaching, the fine flotation concentrate from Woxna Graphite AB can be purified to about 99.4% from 87–88%, and the sulphur content in the product can be reduced to below 0.05% from 0.6%. Acknowledgements WebThrough careful control of total diffusion-limited regime, it is possible to purify carbon black at the expense of far more stable graphite. This shows that targeted exploitation of total diffusion may be used to bypass the classical chemical reactivity.
