For a few months now people have been asking me how I've applied Dean's electrowin cell to refining. Following calls and emails with senior members and moderators, I thought it would be good to throw out there some of the work that's being done.
Whilst the concept and chemistry that Dean so kindly shared with the members is a given, only the practical presentation and structural design can really be improved utilising current technology. The end goal being a cell that anyone can use. Repeatedly, and with a minimum of consumables. I would strongly recommend that anybody who has not read Dean's missives does so post haste. Why? Because the information held in these is revolutionary in terms of bringing processes both up to the modern age, and allowing a home refiner to process product that he/she would have originally thought beyond their reach.
For those who have yet to read the thread written by Deano, you can find it here http://www.goldrefiningforum.com/phpBB3/viewtopic.php?f=37&t=21526
The design, prototyping, materials technology, equipment, and engineering to do this is costly both financially and in sheer time however I hope members will agree that it's a worthwhile exercise.
The pics below detail some of the basic interior cathode carriers. Moving the cathode closer to the anode reduces the [stt]current[/stt] voltage (see posts below) required to operate the cell efficiently thereby allowing more than one cell to operate on one power supply. Allowance has to be made for the cathode increasing in thickness whilst making changing it quickly and efficiently a priority.
The print shown in process is using a rough detail and ABS. The actual material used will be different. I'd welcome any comments or questions that anyone may have.
