Ore Minerals: How they are found, mined, and processed for human use Flashcards
The process of mineral extraction
Iron mining
Modern mining uses _______ to measure magnetic, gravity, and sonic responses of rocks
geophysical techniques
extract ore minerals near the surface of the earth, and uses blasting
Surface mining
3 types of surface mining
Open-pit, Strip mining, and Dredging
common type, a big hole through explosives and blasting
Open-pit mining
removal of thin strips
strip mining
mining from the bottom of a body of water
dredging
extract minerals that can be found beneath the surface of the earth, creating a tunnel means expensive and dangerous
Underground mining
extracting minerals from the ore, refining, and preparing these for use
Mineral processing
What is the process of mineral processing?
Sampling, Analysis, Communition, Concentration, Dewatering
removal of a portion, represents a whole needed analysis
Sampling
evaluate the valuable component in an ore
analysis
valuable components are separated through crushing and grinding, turning it into powdered form
Communition
separate valuable from the raw materials
Concentration
convert it to usable minerals, filter and sedimentation of the suspension and drying of the solid materials
dewatering
