What is Mining and How Does it Work?
A fundamental breakdown of the mining value chain, from prospecting to processing.
**Mining** is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. These deposits form a mineralized package that is of economic interest to the miner.
In the context of General Mining, the process is critical for obtaining materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory.
The Mining Lifecycle
The process of mining involves several distinct stages:
- Prospecting and Exploration: Finding and defining the extent and value of the ore body.
- Development: Planning and building the mine infrastructure.
- Extraction (Production): Removal of the ore from the ground.
- Processing: Separating the valuable mineral from the waste rock (gangue).
- Closure and Reclamation: Restoring the land for future use.
Surface vs. Underground Mining
Broadly, mining methods are divided into two categories: Surface Mining and Underground Mining. Surface mining is much more common, including open-pit and strip mining. Underground mining is used to reach deeper deposits and is generally more expensive and dangerous.
