Study Notes
Mineral Extraction and Processing Overview
- Mining is the extraction of minerals from rock seams or ores, involving the separation of valuable components from raw materials.
- A mineral is a naturally occurring element or compound; an ore contains a high percentage of one or more minerals.
Methods of Mining
- Surface Mining: Extracts ores and minerals located near the earth's surface by removing overlying soil and rock.
- Underground Mining: Involves creating tunnels to access minerals found below the surface, requires explosives, and is typically more expensive and hazardous.
Types of Surface Mining
- Open-pit Mining: The most common method, creating large pits in the ground, used primarily for gravel, sand, and rock mining.
- Strip Mining: Involves the sequential removal of thin strips of overburden above mineral deposits, commonly used for coal and phosphates.
- Dredging: Extracts materials from the bottom of bodies of water like rivers or lakes, crucial for sourcing submerged minerals.
Mineral Processing Steps
- Sampling: Involves removing a portion of material for analysis, crucial for evaluating the ore's composition.
- Analysis: Essential for assessing valuable components; includes chemical, mineral, and particle size analysis.
- Comminution: The crushing and grinding of ores to liberate valuable minerals, with the final product being a powdered form.
- Concentration: The process of separating valuable minerals from waste materials, enhancing the quality of the extracted resources.
