Some tips on improving gold recovery because the Wave Table is a good device for recovering gold from either “hard rock” or “alluvial” (placer) deposits.

Re. Hard Rock gold deposits

If gold is in hard rock, the ore has to be crushed and sufficiently milled fine, in other words ground down. You need to do this in order to free up the small gold particles. Consequently, it is important for small miners and prospectors to be able to crush and grind down their gold bearing ore, before they put over the Wave Table (WT). Otherwise the WT will not work at its optimum performance level.

So it’s a good idea if miners adopt the practice of using a jaw crusher and then a hammer mill (or ball mill etc) that will reduce the ore down to 100% passing 2mm or even 100% passing 1mm in size. This latter size is perfect for running on a WT.

Re. Alluvial/Placer deposits

Again I cannot stress enough the need to get your WT feed size down to 100% passing 2mm and even 1mm (for very fine gold areas). Any coarse gold can be collected with sluice boxes or gold traps which are very easy to set up. It is the fine gold that is difficult to recover — and that is where the WT comes in to play. BUT the feed to the wave table has to be screened (classified) down to a smaller and more manageable-size fraction.

So it is useful to consider the idea of rotating wet screens (we call them trommels), otherwise the wavetable will not operate effectively. Or you could use a wet vibrating screen.

Hope this helps.

This incredible gold separation/recovery device comes in 3 models covering all scales of operation and works on gold, any heavy mineral, also cleans grit from stripped carbon.

The portable 12 volt powered model M5 has just been released and is great for test work in the bush or lab.

The M8 is perfect for bulk sample testing and for full scale production.

The mighty M10 can process up to 10 TPH and has low water and power usage.

Action Mining, who manufacture the Gold Wave Table, also supplies a complete range of assay equipment, prospecting gear and technical books.
