Science Reviewer Presentations #3 Minerals Flashcards
Natural Rock as sediment
Metalliferous minerals and gangue.
Rock Seam or Ore
It is a geologic term
Mineral deposit
It is an economic term
Ore deposit
It is a complete sequence of activities which aims to discover deposits of minerals and rocks that can be used to meet the resource needs of society.
Mineral Exploration
Stage in formulating a project.
Project Design
Stage involves physical activities.
Field Exploration
Project to determine whether it is feasible and should go ahead.
Pre-production Feasibility
Process of mineral extraction from a rock seam or ore.
Mining
Utilized to extract ore minerals that are close to Earth’s surface.
Surface Mining
Utilized to extract ore minerals from the ore body is that is deep under the Earth’s surface.
Underground Mining
It is the process of extracting minerals from the ore, refining them, and preparing these minerals for use
Milling or Mineral Processing
Is the removal of a portion that represents a whole need for the analysis of this material.
Sampling
Is important to evaluate the valuable component in an ore. This includes chemical, mineral, and particle size analysis.
Analysis
Is the process where the valuable components of the ore are separated through crushing and grinding.
Comminution
Involves the separation of the valuable minerals from the raw materials
Concentration
This involves filtration and sedimentation of the suspension and drying of the solid materials harvested from this suspension.
Dewatering
The crushed rocks are submerged in liquid where the heavier/denser minerals sink thus are separated from the tighter minerals.
Heavy Media Separation
If the metal or mineral is this magnetic, the crushed ore is separated from the waste materials using a powerful magnet.
Magnetic Separation
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.
Flotation
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.
Cyanide Heap Leaching
