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. Mineral processingis the practice of beneficiating valuable minerals from their ores.
— There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, …
— Granite quarrying. Granite is a type of rock formed deep below the earth´s surface from slowly cooling magma. Large machinery is brought in to extract (or quarry) the granite from open-pit mines using wire saws or diamond wire saws. ...
As a technique, quarrying is normally only used where raw materials of adequate quality and size cannot be obtained economically by other means. Since natural sand and gravel are not always readily available, for example, a large proportion of the world's annual output of aggregates is produced by quarrying and processing rock.

Quarrying is similar to open-pit mining except the term is commonly applied to the extraction of dimension stone and aggregates. Fewer benches are required in quarrying than in open-pit metal mining ... Because mineral processing applications release organisms into the environment, researchers will have to be mindful of regulations governing ...
Run-of-mine ore is usually too large to be useful for construction or metallurgy. Large particles must be reduced to specific sizes to either comply with aggregate sizing regulations, or facilitate mineral liberation; therefore, in the aggregates and mineral processing industries, run-of-mine ore is broken in crushing circuits by cone crushers. …
— quarry, place where dimension stone or aggregate (sand, gravel, crushed rock) is mined.The products of dimension stone quarries are prismatic blocks of rock such as marble, granite, limestone, sandstone, and slate.After cutting and polishing, these materials are used in the primary construction of buildings and monuments and also for …
