Removing thegold-bearingrock from the ground is just the firststep. To isolate puregold, mining companies use a complexextraction process. The firststepin thisprocessis breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
In thisstep, pour your solution containing thegoldinto the coffee slowly (make sure your coffee filter is over a cup). Be careful not to rip the filter or you will have to start thefiltration processover again. Also, if the water thestripped PCBsare submerged in hasgoldfoils floating around, pour that into the filter, too.
The result of thisprocessis 99.5 percent puregold. The finalstepis to cast thegoldinto electrodes or anodes and place them in an electrolytic cell. The refiners will then pass an electric current through the cell. At the end of thisprocess, thegoldwill be 99.99 percent pure. Reclaiming the Mine; Nogold…
