Extraction stages
1st PHASE
The first phase consists in making the horizontal cut on the mountain. The protagonist of this process is the chain saw, an innovative machine on rails, which makes precise cuts in the rock penetrating like the blade of a knife.
2ND PHASE
The second phase consists in the vertical cut to the mountain and with which a portion of rock called ‘bank’ is separated from the marble mass by using the diamond wire machine.
3rd PHASE
The third phase consists in squaring the blocks: the bank by now overturned is divided into portions by using the diamond wire machine.

Environment 
Kingtone has always considered fundamental, in carrying out its production and extraction activities, the needs of respect for the environment and in particular that of landscape protection aimed at restoring and preserving the quality of the territory.
The company adopts the innovative cultivation system “by sectors”, whereby the recovery of the area takes place at the same time as the extraction works. The quarry area of the cultivated sector is returned to its agricultural purpose already during the cultivation of the next sector.
Before the start of cultivation, the soils are subjected to geochemical analyzes in order to identify the “0” point not to be altered. Furthermore, in compliance with international environmental protection standards, all the guidelines of the UNI EN ISO 14001: 2015 standard are adopted.
