Main Question or Discussion Point

Hello my name is Colin Wilson and I am the inventor of a new mineral separation process.

http://www.coldgold.rotoquad.com [Broken]

I am looking for help and/or a partnership in this endeavor.
As a group I can not think of a better place to start. To test this new method of mineral recovery 3 things are required:

1) The tank circuit.
2) A high power/high frequency oscillator.
3) The physical unit including the conveyance system.

The tank circuit requires good capacitors and a water cooled coil.
The HF oscillator is where I really need the help.
The physical unit can consist of EM shielding and a manual feed system to begin with.

In brief, induction heating relies on eddy currents and the “skin effect” to heat conductive materials. In the case of ferrous material the job is somewhat easier as hysteresis and a lower conductivity also comes into play.

I have small concentrate samples from 3 gold mines (the Yukon, Nevada and Cape Breton).
These samples are very typical with the gold particles averaging about 80 um (.003”).
To rapidly heat particles of this size and conductivity, frequencies in the 20-30 Mhz range are required. Power levels in the low kw range are also required (for a small test base).
Platinum would be easier given its relatively low conductivity but I have little knowledge, at the moment, of how the ore is prepared etc.
I also have a small machine shop and the ability to fabricate and program circuits based on the PIC microcontroller.
Initial tests can be conducted with somewhat larger particles and less conductive material (such as brass) to provide some initial data.
From a purely cost point of view I’ve been considering a spark gap oscillator for the first tests?
Any input etc. would be appreciated.

Purchase an induction heater.
I designed and built one 30 years ago, and I assure you, you don't want to go down that road.
