Assaying Ores to determine gold content

Now this result does not take into account the purity of the free gold in the sample – and most natural gold does contain some silver and traces of base metals including copper. On the other hand, panning does not recover of the very finest gold, and even with small sand sized material, some gold will be lost in the tailings.

Improving the sensitivity and accuracy of gamma activation …

Gold can be assayed with high sensitivity using conventional neutron activation analysis (NAA), but the relatively long half-life of the 198 Au product (2.7 days), and the need for lengthy sample cooling to minimise activity of more common rock-forming elements, makes NAA unsuitable for routine commercial application (Hoffman et al., 1999). The method also requires …

Mineral Jig Concentrator

The jig is the most universal washer ever devised. It is handling in practice a wide range of closely sized coals and ores, mixed sizes of coal from 8-in. to 0 through ¾-in. to 0, and mixed sizes of ores down to 7/32-in. to 0 and even smaller. It is treating materials ranging in specific gravity from that of gold at 19 to that of coal at 1.30.
