Opencast mining is a surface mining operation where we extract minerals from an open “pit” in the ground. This method of mining is the most popular for mineral mining and doesn’t require the use of extractive methods or tunnel digging. Opencast mines are used when minerals or ores are found close to the surface of the earth.

A rather special problem can sometimes arise when analyzing certain t)rpes of copper sulfide ore from an open cast mine. In this case it can happen that, close to the surface, where air has been in contact with the sulfide ore, the ore can be oxidized. Thus a particle of chalkopyrite CuFeSa may be converted to CuFeOa.

Open cast mining. Open cast mining is also known as strip mining and is used for bedded deposits, and most commonly for coal. Although it is similar to open pit mining, the distinguishing characteristic is that the overburden is not hauled away to waste dumps; but rather, it is immediately cast directly into the adjacent mined-out cut.
