Hello folks,
The condition of time response to analysis of precious metals in samples is of importance. If you take an cluster resource sample that contains gold and grind it by violent means, and follow up with processing, the sample may yield gold. Four hours to 3 weeks later the sample will yield nothing. Repeat the grind and it will again produce gold, at least for awhile.
1. The first theory is that the clusters under extreme energy release in their proximity during the grind become temporarily available to colloid chemistry and collection.
2. The second is that clusters have charges to them. They are mono-polar. Micro-molecular minerals such as zircons with traces of halfnium and iron oxide inclusions are attracted to the microclusters and form dense refractory encapsulation of the gold clusters. Therefore the refractory protection is keeping the gold inside of micro-jails. The values just can't get out. This will explain the reason that neutron activation analysis will not detect gold in these samples. Zircon is a tremendous absorptive mineral when it comes to zircon. The neutrons cannot get to the gold for detection. Now if electrical energy of any kind in sufficient quantity is passed through the "jailed" cluster of gold, the charges are temporarily disrupted and the gold cluster can be recovered by a number of chemistry and possibly physical methods. A gold value is collected, concentrated and recovered. Allow the sample to sit for a period of time and the encapsullation of the cluster redevelops.
The trouble is that samples with gold clusters in them, when they are examined by a scanning electron microscope, the values are visible and not encapsullated unless in zeolite cages. Therefore, I leave the choice of the possible correct theory to you. Maybe both have merit. mike
