Zista Gilsonite: Gilsonite Supplier and Powder Factory

Zista Gilsonite stated its activities in 2008 as a division of Zista Group with supply of the rare mineral of Uintaite also called natural bitumen or Gilsonite from Iran. As second largest Gilsonite supplier of the world, Iranian Gilsonite has shown a great potential of market expansion causing over 60,000 MT of natural bitumen annual exports by 2013 mostly in form of Gilsonite Powder. Zista Gilsonite owning nearly 50% market share has established a Gilsonite Powder factory in order to respond to customers’ needs on different concepts including Packaging, Powdering and Powder Sizes (Mesh) and efficient quality control of the raw material Gilsonite supply in form of lumps.

As a major Gilsonite Supplier, Zista Gilsonite had made upstream investment in mining operations throughout the years and has secured a portion of supply by storing the exploited material at its Powder factory. Such action has provided the chance to be a Gilsonite Supplier during all seasons while other suppliers from Iran tend to lack quantified or qualified supply, especially in winter.

In addition to above, Zista Gilsonite owns a research facility in order to make sure the output of the factory is as per requested specifications and to ensure steady exports of Gilsonite Powder.
