Exam #1 Flashcards
Classification, Mining Methods, Cu, Fe, Mn, Al, Ti, Ni, Cr, Co, V, Pb, Zn
Magmatic Ores
Deposits formed from crystallization of magma
Pegmatite Ores
Deposits found in igneous rocks formed from the crystallization of magma at a late state of cooling
Carbonatitic Ores
Deposits found in igneous rocks that are primarily composed of carbonate materials
Epigenetic Deposits
Mineral deposits formed as a result of processes occurring after the initial formation of the host rock
Syngenetic Deposits
Mineral deposits that form simultaneously with the host rock
Diagenetic Deposits
Mineral deposits that form during the physical and chemical changes sediments undergo as the become rock
Hypothermal deposits
High temp, high depth
Mesothermal deposits
Moderate temps, moderate depths
Epithermal deposits
Low temps, low depths
Telethermal deposits
Very low temps
Xenothermal deposits
Temp and depths varies
Vein deposits
Mineral accumulations that form in fractures within rocks
Disseminated Deposits
Mineral accumulations where valuable minerals are distributed uniformly throughout the rock rather than in concentrated veins or masses
Kimberlite
Volcanic ores that forms in vertical structures
K-Feldspar
Minerals found in igneous rocks, important source of potassium and aluminum
Placer deposits
Concentrations of valuable minerals accumulated in sedimentary environments due to moving water
Porphyry Deposits
Large, low-grade mineral deposits in volcanic feeder systems above subduction zones
Main sources of Ti ore
Rutile and Ilmenite
Main product of Ti processing
TiO2 (93%), Ti-metal (7%)
What do we use the main Ti product for?
Whitening agent in paint, plastic, paper, cosmetics.
What do we use the minor Ti product for?
Metal production
Main environmental impacts of Ti production?
Marine placer mining destroys bottom fauna
Mafic rocks
Igneous rocks rich in magnesium and iron
Ultramafic
Even higher Mg and Fe than mafic
