Volt Carbon Technologies has developed a flexible downstream manufacturing process at its Guelph, Ontario facility capable of converting graphite concentrate into either graphene oxide or expandable graphite using the same processing equipment, and has produced multiple batches of both materials for product trials.
The process operates downstream from Volt’s proprietary air classification technology, which dry-separates crushed graphite ore into a graphite concentrate. From that concentrate, the company’s new downstream process can be configured to produce either graphene oxide or expandable graphite without requiring two separate processing lines, an approach the company says supports its goal of building a North American supply chain for advanced carbon materials less dependent on foreign sources.
