Role of particulate fillers in elastomer reinforcement: a review

This is caused by the short range of intermolecular forces and the resulting easy propagation of small cracks or flaws in the material or at its surface under the high local stresses at rela- tively slight deformations. These cracks develop and grow in a direction perpendicular to the direction of the main stress.

Recovering Gold through the Froth Flotation Process

Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
