Mining Massachusetts Institute of Technology
Mining is the extraction of minerals and elements of economic interest from the earth''s surface. As the demand for natural resources increases, the amount of material in mineral deposits decreases. An increase in price of these materials allows companies to continue to profit from mining deposits with lower ore grades.

Coking FSC 432: Petroleum Refining
Three different coking processes are used in the refineries: delayed coking, fluid coking, and flexicoking (a variation of fluid coking). The common objective of the three coking processes is to maximize the yield of distillate products in a refinery by rejecting large quantities of carbon in the residue as solid coke, known as petroleum coke.
