Lesson 5.1: Introduction to the Cycle of Operations
The process of exploitation reduces to two fundamental operations: winning, i.e., freeing the ore from the orebody, although that term is rarely used in ordinary conversation; and materials handling, i.e., transporting the ore to the mineral processing plant. Winning and handling are repeated over and over again, i.e., they are cyclic.

Steps of Surface Mining : Operation: Strip out overburden (becomes spoils) Traditional surface mining methods fall into two broad categories based on locale: I) Mechanical excavation methods { such as: Open-pit (or Open-cut or Open-cast) Terrace; and Strip mining}. II) Aqueous methods {such as: Placer and In-situ leaching (ISL)/ Solution mining}.

It is an overhand mining method that relies on broken ore being left in the stope to be used as the “working floor” and to support the walls. During the mining cycle, only 30 35% of the ore blasted is extracted being equivalent to the swell factor of in-situ ore to broken. When mining is complete to the next upper horizon, the ore is extracted.
