FIRST NAME ___Graham ____ LAST NAME _____Nagle-Deamer______ CLARKE VALUES 1. Some ore metals are more valuable than others. To be economical, ore deposits must contain a sufficient amount of the metal of interest to make mining profitable. We defined the Clarke Value as a concentration factor that is the amount a particular resource must be enriched above the resource’s normal crustal abundance to be economically minable. Minable grade refers to the minimum concentration a particular resource in a particular ore deposit must have for that volume of rock to be economically mineable. Use the data provided to calculate the concentration factor (Clarke value) for each metal. A B B/A element crustal wt % minable grade (wt %) concentration factor (Clark value) aluminum Al 8.0 28. 3.5 iron Fe 5.8 40. 6.89 copper Cu 0.0028 0.52 185.714

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
