Reno Chris African mining "secret": Gold PGMs including their sulfide forms and Diamonds all stick to vaseline petrolium Jelly. Make a simple sluice box with a plastic sheet layer in the bottom and coat it with a layer of vaseline. low angle slow water run your crushed ore over it. Re- run ore to make sure you got most all of it and the remove the plastic sheet scrape off the vaseline with a plastic paint scraper and thin the vaseline with acetone till watery consistancy the metals will drop to the bottom of your comtainer. de cant the fluid. put in a fireproof metal container ... stainless steel bowl. light on fire to burn of vaseline / acetone residue and process from there as you wish. Sounds wierd but it works well. Best of success in your efforts. Ron
