A method to focus forward momentum of a material increase the velocity of a specific material or a number of specific materials, said method comprising the steps of: introducing a slurry of material into a high velocity accelerator, where said high velocity accelerator is adapted to impart an increase in the velocity of the materials introduced therein; expanding the volume of the slurry introduced into the high velocity accelerator without diminishing the velocity of the material; entraining said expanded slurry through injection of a liquid at high velocity towards an outlet port located in the high velocity accelerator; and focusing the entrained slurry onto a pre-determined point located proximate the outlet port of the high velocity accelerator.

A high velocity accelerator comprising: an internal chamber; a material inlet port; a material outlet port; a back wall surrounding the inlet port; an internal wall having a first end connected to the back wall and a second opposite end tapering to the outlet port, the first end being located proximate the inlet port and the second end being located proximate the outlet port; a plurality of injection ports positioned along the periphery of the internal wall proximate the first end; wherein said inlet port having a diameter smaller than the diameter of the internal chamber, and the injection ports are adapted to inject at a high rate of displacement a fluid which, in operation, will create a vortex inside the chamber thereby entraining a material towards the outlet port. Uses and methods using such are also disclosed.

A method of pulverizing solid material for the purpose of extracting metals which may otherwise not be recoverable and/or cost prohibitive using conventional means and processes, said method comprising the steps of: using a gas to create a fluidized flow of previously crushed solid material; transporting the fluidized flow of solid material to an apparatus which induces a high velocity flow stream in a constricted low-pressure stream; causing a rapid acceleration on a rotational angle of the crushed solid material resulting in increased interparticle collisions and collection of solid particles; and ejecting the material at a high rate of speed from the apparatus to a focal point where the material is pulverized.
