As a volcanic rock, phonolite is formed predominantly from alkali feldspar (a group of rock-forming minerals such as sanidine and microcline that are commonly found in igneous rocks) and other such compounds. Applications for phonolite include ceramics, glass production, gravel aggregates and use as a dimension stone.
The rock itself boasts high alkali content and a high proportion of aluminium oxide, as well as various other properties depending on its formation and transformation.
After extraction, multistage blasting process treatment begins, producing crushed sand with grain sizes of 0.2mm and 0.3mm from the rock fragments. This material can then be used as a flux in the ceramics and glass production industries, as well as in the conditioning of slag in steel production. Finer grain sizes can also be used in welding technology.
