Fig 18.2 Avg Consumption/Person/Y; Class, name one product you use from each resource

Fig 18.2. USA Consumption Exceeds ProductionClass: What are chromium and nickel used for? The other elements?

Fig 18.3Enrichment scale If concentration of the element in a mineral or rock is greater than the enrichment factor, the rock or mineral is an oreClass: Define an ore in terms of extraction profitably

Fig. 18.4 Minerals Form From Hydrothermal VentsClass: Name three elements of economic interest found within vents

Fig. 18.4B“Black Smoker” Copper Minerals Being Formedsee Textbookplay video

Fig. C18.1 Hydrothermal Vents On LandSome very interesting chemistryZnS and PbS, good ore minerals,have low solubilitiesHigh concentrationof Cl in the brine solution “complex” Zn and and Pb leading to high concentrations of Zn and Pb

Fig. 18.5Vein containing copper, zinc, and lead

Fig 18.6 Gypsum, halite, and potassium deposits Class, how does the anthroposphere use these three deposits??

Fig 18.7Sedimentary Iron depositChert, Iron-Silca-Carbonate Class, was/is the USA a principal source of iron from these deposits?

Fig 18.7A Silica leached, left with iron rich ore, 60% iron!! Class: What “sphere” is responsible for the removal of silica from these deposits

Fig 18.8 An apparent sedimentary deposit rich in copper, zinc and lead minerals Class: What two spheres are responsible for these deposits??
