allsliming process. In the early days gold was recovered from stampmilled material by gravi ty concentration only. Later, in 1890, the product of stamp milling was split into sand and slime fractions. The sand was treated by percolation cyanida tion, whereas the slime was accumulated for lack of a suitable treatment process.

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

Geology Gold Mines Desert Mining History Stamp Mill A stamp mill was a mechanical crusher, noisy, heavy and somewhat awkward to operate. The stamps were heavy metal weights that were lifted and dropped on the ore by a crankshaft. The crushed ore would then be further refined, usually by a mercury or cyanide process. The process explained:

It exploited the fact that gold dissolves in a solution of sodiumcyanide. Millers washed pulverized ore with the solution, poured off the result, and mixed it with zinc shavings, which left the gold behind. In 1896, Professor Robert Jackson from the University of Nevada School of Mines, used the cyanide process on mill tailings in Washoe Valley.
