Hi all just quickly would like to introduce myself and happy to partake and share knowledge .I am 56 years and been involved with mining most of my life with our farm on huge greenstone gold belt .The last four years using the minelab 5000 metal detector with great success.Have just recently opened up a washing plant and processing the smaller sub gram nuggets the metal detector misses.My problem is finding the most effective recovery of fines in the black sands.am having trouble trying to get hold of Hokes book so any suggestions will be greatly appreciated.
