- Definition: Concentrated Ore
- Key Points: Dressing of Ores
CISCE: Class 10
Definition: Dressing of Ores
The process of removing gangue, the rocky impurities like SiO2 present in an ore, is called concentration of an ore or ore dressing and the purified ore is called concentrated ore.
CISCE: Class 10
Key Points: Dressing of Ores
- Ore dressing removes impurities (gangue) from ore; the result is concentrated ore.
- Gravity separation uses water to separate denser ore from lighter impurities.
- Magnetic separation separates magnetic ores from non-magnetic impurities.
- Froth flotation separates sulphide ores by forming froth with pine oil and air.
- Leaching dissolves the ore using chemicals; flux is added later to form removable slag.
