Closure and reclamation of the mine site has become a necessary part of the mine life cycle because of the demands of society for a cleaner environment and stricter laws regulating the abandonment of a mine. Reclamation has been added to these stages since the first edition, to reflect the times. Likewise, development and exploitation are closely related stages they are usually considered to constitute mining proper and are the main province of the Mining engineer. Geologists, Geophysics, and Mining engineers often share responsibility for these two stages-geologists more involved with the former, mining engineers more with the latter. Prospecting and exploration, precursors to actual mining, are linked and sometimes combined.

Harraz Presentation The Mining Cycle 1 February 2016 9 STAGES IN THE LIFE CYCLE OF A MINE PROJECT The overall sequence of activities in modern mining is often compared with the five stages in the life of a mine: Sequence of Activities in Mining: Stages in the Life of a Mine: Responsibility Geologists, Geophysics, and Mining engineers often share responsibility for these two stages-geologists more involved with the former, mining engineers more with the latter Stage 1 : Prospecting 1)Prospecting 2) Exploration (discovery) Stage 2 : Exploration and Assessment 3) Feasibility study Stage 3 : Construction 4) Mine development 5) Extraction/ production Mining engineer Stage 4 : Exploitation or Operation 6) Processing/ beneficiation/ milling 7) Marketing Stage 5 : Reclamation 8) Closure/post-mining use Prof.

Harraz Presentation The Mining Cycle 1 February 2016 3 WHAT IS MINING? Mining The activity that removes from the earth’s crust the abnormal concentration of metal found in the deposit Mining is extracting ore or minerals from the ground Mine An opening or excavation of the earth from which minerals are extracted Prof. Harraz Presentation The Mining Cycle 1 February 2016 Outline of Topic 2: WHAT IS MINING? MINE LIFE CYCLE LIFE CYCLE OF DEPOSITS LIFE-CYCLE OF A MINE PROJECT STAGES IN THE LIFE CYCLE OF A MINE PROJECT: 1) Prospecting (Mineral Deposit) 2) Exploration (Ore Body): 3D modeling software's for mining sectors Mineral Resource Mineral Reserve 3) Development 4) Exploitation (Mine): MINE PLANNING CYCLE 5) Reclamation: ENVIRONMENTAL IMPACTS OF NONRENEWABLE MINERAL RESOURCES: SOURCES OF METAL POLLUTION Harmful Environmental Effects of Mining Persistent, Bio-accumulative and Toxi (PBT ): Lead Mercury Cadmium Arsenic We will explore all of the above in Topic 2.
