Open pit mines can be used in coal mining, and they are used extensively in quot;hard rockquot; mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

In modern times though, mining for gold is a much more intensive, yet sophisticated process. Most surface, or alluvial gold has been found, which is why gold is mainly mined from the earth today. Its largely a matter of technology and requires much expertise and elaborate equipment. Mining for gold today can essentially be broken down into 9
Waste rock from the open pit mine is used to build the embankment structures. The embankments retain the tailings slurry in a pond where solids settle and compact. Water is decanted off and used in the process plant or treated before it is discharged. See more detail on tailings disposal
An Overview of the Open Pit Mining Process Openpit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling.

Once mining engineers know where gold is located and what other materials surround it, the mining process can begin. If the gold is located close to the surface, its mined with openpit mining techniques. Gold thats located farther below the surface is collected with underground mining methods.
