Deconstructing the Leaching Ratio
(Springer, 2020)
The heap leaching process has been widely used for recovering different metals since its first application at the end of the 1960s. In Chile, copper production via heap leaching has accounted for between 30 and 40% of ...
How to select the best portfolio of oil and gas projects?
(Canadian Inst Mining Metallurgy Petroleum, 2008-05)
The traditional analytical tool for selecting portfolios of financial assets is Markowitz's mean-variance model. The final product of this model is the efficient frontier. Markowitz's approach comes up with an infinite set ...
