Questions and Answers
Match the following terms related to mineral processing with their definitions:
ore dressing = the process of separating particles according to their sizes comminution = breaking down a substance into smaller pieces drying = the removal of mechanically held water or moisture from concentrate, or other solid materials by evaporation grinding = the process in which the particle size of the ore is progressively reduced through crushing and grinding
Match the following mineral processing terms with their corresponding descriptions:
ore dressing = the process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate containing most of the ore minerals and a tailing containing the bulk of the gangue minerals sizing = the process of separating particles according to their sizes drying = the removal of mechanically held water or moisture from concentrate, or other solid materials by evaporation grinding = breaking down a substance into smaller pieces

Study Notes
Mineral Processing Terminology
- Mineral processing involves various techniques and processes that separate valuable minerals from ores.
- The field includes terminology that is crucial for understanding processes, operations, and techniques used in mining and metallurgy.
Common Terms in Mineral Processing
- Crushing: A mechanical process that reduces the size of ore into smaller particles to facilitate further processing.
- Grinding: A subsequent step after crushing, grinding further breaks down particles to micron levels for mineral liberation.
- Flotation: A separation technique that uses differences in the hydrophobicity of minerals to separate valuable minerals from waste material.
- Leaching: The extraction process that involves dissolving minerals from ores using chemicals (like acids or alkalis) to isolate desired elements.
Key Processes
- Concentration: The process of increasing the purity of a valuable mineral through methods like flotation, gravity separation, or magnetic separation.
- Agglomeration: A technique that involves gathering or collecting particles into a mass or cluster for better handling and processing.
- Sintering: A thermal process that fuses particles together to create a solid mass, which is essential for certain ores before smelting.
Purpose and Application
- Understanding these terms and processes is critical for efficient operation within the mineral processing industry.
- These methods are aimed at improving recovery rates, increasing efficiency, and reducing costs in mineral extraction and processing.
