Surface Mining

Question 10

Utilized to extract ore minerals from the ore body is that is deep under the Earth’s surface.

Answer 10

Underground Mining

Question 11

It is the process of extracting minerals from the ore, refining them, and preparing these minerals for use

Answer 11

Milling or Mineral Processing

Question 12

Is the removal of a portion that represents a whole need for the analysis of this material.

Answer 12

Sampling

Question 13

Is important to evaluate the valuable component in an ore. This includes chemical, mineral, and particle size analysis.

Answer 13

Analysis

Question 14

Is the process where the valuable components of the ore are separated through crushing and grinding.

Answer 14

Comminution

Question 15

Involves the separation of the valuable minerals from the raw materials

Answer 15

Concentration

Question 16

This involves filtration and sedimentation of the suspension and drying of the solid materials harvested from this suspension.

Answer 16

Dewatering

Question 17

The crushed rocks are submerged in liquid where the heavier/denser minerals sink thus are separated from the tighter minerals.

Answer 17

Heavy Media Separation

Question 18

If the metal or mineral is this magnetic, the crushed ore is separated from the waste materials using a powerful magnet.

Answer 18

Magnetic Separation

Question 19

The powdered ore is placed into an agitated and frothy slurry where some minerals and metals based on physical and chemical properties may either sink to the bottom or may stick to the bubbles and rise to the top thus separating the minerals and metals from the waste.

Answer 19

Flotation

Question 20

This method is used for low-grade gold ore where the crushed rock is placed on a “leach pile” where cyanide solution is sprayed or dripped on top of the pile.

Answer 20

Cyanide Heap Leaching
