Miller tables work more or less. Like Dan pointed out, what works great for one character of gold may not and possibly won't work for another type of gold. That being said, there is a product that I'm going to use for my variation of a Miller Table: Herculiner truck bed liner. 1 quart lines roughly 15 square feet. It is polyurethane with rubber crumbs embedded in it. One cautionary note: The solvent is xylene and not the stuff for unventilated use and wear gloves. My application will be on an removeable insert within the table frame. The reason? I would rather remove a liner for washing than try to tilt the table and brush the gold off with the rubber crumbs fighting me the whole way. The liner itself? 20 ga aluminum available at most any hardware store. The Herculiner is available at most any larger auto parts store. Currently I just use rubber v-rib in a clean-up sluice. Most of the gold I recover is in the 250-500 micron class. Flat with rounded edges. I use a 500 gph bilge pump for the water supply. Depth of water is NOT a major factor, but the angle is fairly critical. Hence my reason for a removeable liner. Set the frame at the right angle and just leave it alone. For those who just have to use a neoprene rubber bedding material, there are several options. The rubber is available in sheet form from companies like MSC or use Devcon Flexane castable liquid or brushable available from the same sources as the sheet rubbers. Like I said at the beginning. Nothing new, just new applications for existing materials. |

Is the rubber v mat the deep v or shallow v ? Thanks, baub |

It still won't be completely clean, but I always finish in a pan anyway. I am a fan of Chris Ralph's use of RE magnets per his ICMJ article and in his book. I suck the cleanest gold up with a glass eyedropper. I don't try to clean each pan, but rather get the easy mags and gold out, then add more cons. Just my opinion on the vinyl ribbed material, but from my experience it doesn't work any better than a miller table, i.e. the angle is critical while the deep v-rib is more lenient on angle. Try to keep in mind that I hog the material in. I've had more than one person tell me I was throwing away flour gold, but every time I have a larger percentage of the smaller fractions (down to 100-150 mesh) so it might be the thousands of hours slinging a pan that is the difference. Were it not for the low tenure, I could be content just panning. Hope this helps. Eric |
