What is Stone Quarrying Quarrying is the process of collecting stones from the natural rock surfaces. Site selection and methods used for quarrying for construction works is discussed. Quarrying of stone is completely different from mine. Mine belongs to underground operation only whereas quarry is carried out on exposed surface of natural rocks.

4.1 Quarrying. The quarrying operation cuts a block of stone free from the bedrock mass by first separating the block on all four vertical sides and then undercutting or breaking the block away from the bedrock. If the block is large it is called a "quarry block" and will be cut into smaller blocks at the quarry.

Quarrying by use Of Channeling Machines. In this method the channeling machines are driven by steam compressed air or electricity are used to make vertical or oblique grooves or channels on the rock mass These machines make rapidly the grooves having a length of about 24 m a width of about 50 mm to 75 mm and depth of about 240 cm to 370 cm.

2016-2-26 · crushed. The ore is then ground to flotation size approximately 65 mesh. Through flotation and filtering processes a high grade concentrate containing approximately 64 per cent iron is recovered. The filtered concentrate is shipped to steel plants where it is mixed with coarser ores before sintering.
Stone quarrying is the multistage process by which rock is extracted from the ground and crushed to produce aggregate which is then screened into the sizes required for immediate use or for further processing such as coating with bitumen to make bituminous macadam (bitmac) or asphalt.
