The 5 Stages of the Mining Life Cycle
Mining operations are complex.
They aren’t your run-of-the-mill type projects. These billion dollar complexes consist of various interconnected projects, operating simultaneously to deliver refined commodities like gold, silver, coal and iron ore. It’s a five stage process and we’ve broken it down using GIFs.
The beginning of any mining project begins with the exploration stage. It’s where the magic happens. Companies enlist geologists and others to prospect remote areas in search of mineral deposits. Methods such as geological surface mapping and sampling, geophysical measurements and geochemical analysis is often applied at an early stage to pin out potential deposits.
2. Mine-site design and planning
Once mapping and mineral resource data is collected, and the results are strong, the project can move forward to the design and planning stage. This typically consist of studies to help companies determine if and how a project can be safe, environmentally sound, economically viable and socially responsible.
If you build it, they will come. The construction process occurs after research, permitting and approvals are complete. Construction of mining sites invovles building roads, processing facilities, environmental management systems, employee housing and other facilities.
The two most common methods of mining are surface and underground mining. The method is determined mainly by the characteristics of the mineral deposit and the limits imposed by safety, technology, environmental and economical concerns.
The first step in the production stage is recovering the minerals. This is the process of extracting the ore from rock using a variety of tools and machinery.
The second step is processing. The recovered minerals are processed through huge crushers or mills to separate commercially valuable minerals from their ores.
Once processed, the ore is then transported to smelting facilities.
The final step in production is smelting. This process involves melting the concentrate in a furnance to extract the metal from its ore. The ore is then poured into moulds, producing bars of bullion, which are then ready for sale.
5. Closure and reclamation
The fifth and final stage in mining operations is closure and reclamation. Once a mining site has been exhausted of reserves, the process of closing the site occurs, dismantling all facilities on the property. The reclamation stage is then implemented, returning the land to its original state.
A comprehensive mine rehab (rehabilitation) program has many clearly stated objectives which may include:
• ensuring public health and safety
• minimizing environmental effects
• removing waste and hazardous material
• preserving water quality
• stabilizing land to protect against erosion
• establishing new landforms and vegetation

What are the 5 stages of the mining life cycle?
There are five stages of the mining life cycle, these include: exploration, mine-site design and planning, construction, production, and closure and reclamation.
What is mine rehabilitation?
According to the Department of Industry, Tourism and Resources, mine rehab (rehabilitation) is “the process used to repair the impacts of mining on the environment. Mine rehabilitation can also be referred to as coal mine rehabilitation, land rehabilitation, mine site rehabilitation or mine site restoration.
What are the different types of mine rehabilitation?
According to the Minerals Council of Australia, there are several different types of mine rehabilitation including: cropping, conservation, grazing, and native restoration.
Why should a mine be rehabilitated?
According to the Federal Department of Industry, Innovation and Science, there are four key factors that make up the business case for mine rehabilitation. They are:
1. Project approval
2. Compliance risk
3. Financial liability
4. Reputational risk
