Fig. 1, above shows an illustration of a Open Pit Surface Mine. The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine''s life." To expose and mine the ore, it is generally necessary to excavate and relocate ...

This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.
Openpit, opencast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks are found near the surface.

I recently requested an upgrade to the Open Pit > Open Cut Design > Pit Topography tool. Basically, what the tool does is an automated boolean of two triangulated surfaces: a pit design and an existing topography. The result can give one or all of three things: a new surface topography, a mined solid or an intersection of the two surfaces.
