The tuff landscape of Cappadocia begins around 250 kilometres south-east of the Turkish capital, Ankara. Here, where underground caves are home to rock castles and even entire hidden cities, dozens of hot-air balloons soar above the unique scenery and take in the sunrise. These mountains were originally formed from porous volcanic material – and the vitric tuff is now used all over the world as processed pumice. This material is particularly suitable for ecological construction, as the volcanic rock has a low weight and ensures that construction elements deliver outstanding insulation. The mining operators from the region entrusted their pumice production to the experienced allmineral team, marking the first time ever that our company has used sustainable dry processing in this context.
