The separation of minerals from gangue is called mineral processing. Oftentimes, inefficient processing methods can produce gangue that still holds an ample amount of valuable minerals. As values of minerals increase, it can even be profitable to reprocess gangue to extract additional minerals …

The highwalls of a quarry are often of imposing height and steepness, some attaining overall vertical dimension approaching 300m. Note: Crushed limestone may be mined in a quarry, but it produced by the mining method known as open pit mining, and dimension stone is extracted from a quarry using the mining method known as quarrying.

A quarry is a place where rocks, sand, or minerals are extracted from the surface of the Earth. A quarry is a type of mine called an open-pit mine, because it is open to the Earth's surface.Another type of mine, a sub-surface mine, consists of underground tunnels or shafts.. The most common purpose of quarries is to extract stone for building materials.

In other words a quarry is a big man-made hole in the ground from where minerals or rock are taken out. Quarries are made when big deposits of commercially helpful minerals or rock are found close to the Earth's surface. Quarrying is a type of mining and is also called as open pit mining or strip mining.

Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes. The mineral exposed is completely extracted.
