Mining Process The conversion of natural stone marble, granite, slate, etc. from the quarried mineral to the decorative home accent is a timely process. Blocks are cut from the natural quarries and transported to factories for cuts into slabs and tiles.
MINING. The first step in our mining process is to strip overburden which is the rock and soil overlying a resource away from the resource. We use multiple types of equipment to do this, such as scrapers, excavators, and haul trucks, depending on the digging conditions.

Machines and equipments for stone, gravel and sand processing are mainly used in building industry. The range of machines type is biggest in this branch. It starts from the largest high-capacity stationary aggregates, including medium types in semi-mobile design
Under a Bluestone Exploration Authorization, small quantities of stone can be extracted to determine if the material is workable and marketable. A landowner or quarryman can determine whether a potential deposit is worth mining before making significant investment of time and money to apply for a full Mined Land Reclamation Permit.
Fiber separation in mechanical pulping is less dramatic. In the stone groundwood process, de-barked logs are forced against rotating stone grind-ing wheels that are constantly washed by a stream of water. The ground pulp is then screened to remove course debris, thickened, and stored for the paper-making process.
