Lignite

Lignite is evaluated within the Energy raw material group. Its chemical code or representative formula is No fixed formula. Mineralogical composition, purity, grain size and associated minerals determine technical and commercial suitability.

Use conditions vary according to deposit characteristics and processing route. Project-specific product claims must therefore be supported by representative sampling, laboratory analysis and application tests.

The displayed chemical code or formula is a general identifier. Natural ores and industrial products may contain associated minerals and variable compositions.

Uses

  • Mining and mineral-processing studies
  • Industrial raw-material and technical applications
  • Laboratory, product-development and quality-control studies
