The document outlines a 7-stage process for mineral liberation, separation, and extraction: 1) blasting, 2) primary crushing, 3) secondary crushing, 4) grinding, 5) separation by size, 6) separation by values, 7) extraction of values. It then discusses process design, mineralogy, technological tests, and various process routes including crushing, grinding, gravity concentration, thickening, flotation, and smelting.

insitu stress field in earth crust, stress environment in mines, effects of horizontal stress, control measures of horizontal stress, stress mapping, measurement of insitu stress field
Room and Pillar mining method is one of the oldest existing mining methods. This system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. Usually those room and pillars are uniform size. Pillars may or may not be removed after extraction.
Used for soft as well as hard rock mining and is commonly associated with coal, potash, uranium, and other industrial materials.

Separation of Macromolecules by Their Size: The Mean Span Dimensioncypztm
Size Exclusion Chromatograpphy (SEC, also called GPC) separates polymer molecules by their size in dilute solution, but which size parameter to use has been a matter of debate. This presentation contains a brief summary of our work on this problem.
This was my pharmaceutics presentation for mixing. Provides definitions, mechanism, types of mixers etc.
P.S: I am not the sole presenter. Ideas are from my two other colleagues as well.
