Lecture 7 Flashcards
What minerals make bronze?
Copper and tin
What is an ore?
Metals that are combined to other elements.
What’s the difference between high and low grade ore?
High grade ores wouldn’t have waste rock, while low grade ores do.
What is smelting?
When heat is added to the ore to separate the material you don’t want in a molten state.
What is gangue?
The material you don’t want (waste)
What’s the present crisis we’re dealing with in the 20th century?
We’re generating waste and causing increase risks of pollution and GHG.
Is natural contamination as bad as anthropogenic contamination?
They both create bad affects on people and nature. Natural contamination is due to the parallel pathways having large amounts of heavy metals.
What are industrial minerals known as?
Non-metallic minerals
What’s the difference between precious and base metals?
Precious metals are not easily accessible and are expensive (ex. gold and silver) while base metals are common and cheap.
What are the two broad categories of metallic minerals?
Abundant (ex. Fe, Al, Mg, Mn) and scarce.( ex. Cu, Pb, Ni, Au, Ag)
What is atomic substitution?
When some metallic minerals occur where the dominant element is another mineral.
Briefly explain the exploited block diagram.
This diagram shows what to be concerned about when exploring for oil and gas. They’re interested in sedimentary rock (middle) and metallic minerals are in the crystalline rock (bottom).
What minerals are commonly located on the seafloor?
Cooper, zinc, manganese and sulphur
What are nonmetallic minerals used for?
Fertilizers, chemical industry and building and construction industry
What are dimension stones?
It’s a type of rock that has an attractive look for the face of buildings, gravestones, etc.
