Helix EOOD has been mining raw vermiculite in Livade deposit near the village of Belitsa, Ihtiman municipality. Vermiculite is extracted by using open-pit mining techniques, through digging.

After being extracted, the raw material is screened by on-site fitted mobile screening plant. The selected raw vermiculite is transported to the Raw Vermiculite Separating Installation in the village of Gara Elin Pelin where it is enriched by using a drying method. The Raw Vermiculite Separating Installation is newly built, operating fully automated production processes. These processes include drying, screening, pneumatic-gravitational and magnetic separation. Quality control is strictly exercised at all stages of vermiculite processing.

An on-site testing laboratory has been closely monitoring the characteristics of the produced vermiculite concentrate, such as: proper separation of fractions, bulk weight, expansion rate, humidity and impurities as prescribed by the Vermiculite Test Methods of the Vermiculite Association (TVA). A qualitative analysis for asbestos is performed by the internationally-recognized accredited IOM Laboratory in Edinburgh, Scotland.

Generally vermiculite concentrate is packaged in Big Bags of 1-1.2 tons. Helix EOOD may provide other forms of packaging according to the specific customer’s requirements.
