The quarrying process consists of separating large blocks, sometimes called loafs, from the surrounding rock. These blocks may be 6 metres high by 6 metres deep and 12 to 18 metres (about 40 to 60 feet) long, and they may weigh in the range of 1,200 to 2,000 tons. (Such large blocks are subsequently divided into mill blocks weighing 15 to 70 tons.)

Thus, the quarrying industry has sought advanced crushing technology and process control strategies to maximize profit (Svensson and Steer, 1990). On the other hand, in the mineral processing industry, the product of a tertiary crushing circuit typically goes through several more comminution and concentration steps until the valuable …

The raw stone is then polished and its quality and colour are looked at. Step 3: If the stone is found to be of good quality and it has been approved, the extraction process can begin. Extraction is done by breaking large chunks of the raw material to loosen them and create smaller pieces. Step 4: Once they've been extracted the stone is ...
