Processing of ore from a lode mine, whether it is a surface or subsurface mine, requires that the rock ore be crushed and pulverized before extraction of the valuable minerals begins. After lode ore is crushed, recovery of the valuable minerals is done by one, or a combination of several, mechanical and chemical techniques.
The ore body formation affects the mining method and the sequence of extracting different zones so that the beneficiation process can be effective. Changes in ore properties, such as ore gold distribution and hardness have influence in gold liberation and consequently will be affected the recovery process.

Separation of acoustic and vortical waves can be made by using the normal mode method (cht1.doc: Waves in Uniform Flow on Half Plane). Here we attempt to separate the waves based on their physical origins. As we know, acoustic waves are generated by oscillations of the fluid element under the balance of inertia and elastic restoring forces.
