Surface Mining & Quarrying Techniques
In its simplest form, surface mining can be described as a method of extracting minerals or rock from just under the surface of the earth. Surface mining itself can be broken down into multiple categories. In hard rock mining, much of the world's annual output of copper, gold and iron ore is won from open-pit operations. Other commodities produced from open-pit mining include diamonds, molybdenum, manganese, lead and zinc, uranium and a variety of industrial minerals, such as borates, talc and specialist clays.Open-Pit Mining Method and Process Epiroc

Quarrying My Time at Portia Wiki Fandom
Quarrying, also colloquially referred to as mining, refers to obtaining crafting materials by breaking rocks. The player can break rocks with either Pickaxes or a Mini-Drill, although larger rocks require stronger tools and/or a higher attack to break. Larger rocks can be quarried after gaining a high enough Attack stat.

What the difference between mining and quarrying?
Types of materials: Mining is typically associated with the extraction of minerals such as coal, gold, copper, diamonds, and iron ore, while quarrying is associated with the extraction of construction materials such as limestone, marble, granite, and sandstone. Depth of extraction: Mining often involves extracting materials from deep World demand for copper for the year 2011 was about 20 million tonnes. World reserves of copper are estimated to be 700 million tonnes. Most of the copper used is obtained from copper ores, which are mined. The copper ore chalcopyrite is heated in a furnace to produce copper sulfide, CuS The furnace is heated by burning fossil fuels.(1) (2) MME Revise
