Zentek

Zentek Ltd (formerly known as ZEN Graphene Solutions and before that, Zenyatta Ventures) is a mineral exploration and development company based in Ontario, Canada. Zentek is developing the Albany Graphite Deposit – a rare hydrothermal graphite deposit with the potential to produce a natural, high-purity graphite that may compete in high-technology markets traditionally reserved for synthetic graphite.

The company's high crystallinity graphite can be upgraded without the use of aggressive acid (HF) or high temperature thermal treatment. Zentek has developed an environmentally friendly metallurgical process flowsheet that consists of grinding, flotation and caustic treatment using sodium hydroxide. The company states that it has been able to achieve an extraordinary carbon purity result of >99.9 percent in bench-scale tests, using this proprietary and environmentally friendly purification process.

According to Zentek, current end uses for its graphene materials include composites (concrete, rubber and plastics), energy storage and environmental applications but many more are under development.
