Question

Which of the following methods is NOT typically used for concentrating a dilute ore?

P SRAVAN KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
 **Primary Concept**: Ore concentration techniques
 **Related Topics**: Metallurgy, mineral processing, separation techniques
 **Prerequisites**: Basic understanding of physical and chemical properties of minerals.
## SOLUTION PATHWAY
**Given Information**:
  The question asks to identify the method NOT used for concentrating dilute ores.
**Method & Steps**:
 1. Analyze each option to determine its suitability for ore concentration.
  Reasoning: Ore concentration aims to increase the concentration of valuable minerals in an ore by separating them from unwanted gangue materials.
 2. Evaluate each method:
  Froth flotation: Uses differences in hydrophobicity to separate minerals.  Effective for many ores.
  Magnetic separation: Uses magnetic properties to separate magnetic minerals from non-magnetic ones. Effective for ores containing magnetic minerals.
  Gravity separation: Exploits differences in density to separate minerals. Effective for ores with significant density differences between valuable minerals and gangue.
  Distillation: A separation technique based on boiling points. Not applicable to solid ore concentration.
 3. Identify the unsuitable method:
  Result: Distillation is not used for concentrating solid ores.  It's used to separate liquids based on their boiling points.
  Verification: The other three methods are all common techniques in ore concentration.
 ## OPTION ANALYSIS
A :x: Froth flotation is a common method for concentrating ores.
B :x: Magnetic separation is used for ores with magnetic components.
C :x: Gravity separation utilizes density differences for separation.
D ✓: Distillation is a liquid-liquid separation technique and not suitable for solid ores.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing distillation with other separation techniques: Understanding the principles behind each method is crucial.
  2.Overlooking the physical state of the ore: Ore concentration deals with solid materials, whereas distillation is for liquids.
 **Quick Tips**:
  1.Focus on the physical and chemical properties used in each separation technique.
  2.Remember that ore concentration involves separating solids, not liquids.
