Sand and gravel quarries are pumped to allow them to be worked dry or operated as lakes with extraction below water. A conveyor draws raw material into the processing plant, where it is washed to remove unwanted clay and to separate sand. Sand separated during processing is dewatered and stockpiled.

So, a quarry is any such working on the surface of the earth where minerals are extracted. Quarries are also known by other names around the world: 'surface mine', 'pit', 'open pit' or 'opencast mine'. Within the UK, the largest quantity of mineral extracted by quarrying is used for construction and known as "aggregates".

What is Limestone? Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3.It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.
