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.

The recovery of gold from gold-bearing ores depends largely on the nature of the deposit, the mineralogy of the ore and the distribution of gold in the ore. The methods used for the recovery of gold consist of the following unit operations: 1. The gravity preconcentration method, which is used mainly for recovery of gold from

This procedure tends to en- hance recovery by entrainment and is more or less equivalent to rougher flo- tation in practice. Concentrates were usually collected at 1/2, 1, 2, 4 and 8 minutes. Froth was removed by hand scraping at a constant depth every 2 s in the first minute and every 5 s thereafter.

The SX/EW Process has its roots in analytical chemistry where it is used to separate one metallic ion from another. It was first used as a large-scale process during World War II for the recovery of uranium from its ores. The key to the process is the development of organic extractants that are specific to the metal to be extracted.

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.
