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.

The flyer explains how the Action Mining GOLD WAVE TABLE works:

Separating by specific gravity, the sand forms in riffles directly under the standing wave of water. Even light blond sand forms riffles, not washing away.

Due to the Standing Wave principle, the heaviest particles remain through the low motion area of the Standing Wave. The wave itself moves; the water directly beneath the wave tends to stand still. The further from the top of the wave, the less motion is in the water.

Thus, the heavier the particle the deeper it will ride and the less motion it will see. The “Riffle Pump” attached to the top bar of the Riffle Bar assists in dropping ‘float gold’ to the table surface, enabling a faster production run without fear of losing gold or other metals that normally would be lost on most tables.

In view of the fact that the table top moves back and forth, the micron particles of heavy material (gold, PGMs, scheelite, copper, zinc oxide, etc.) sink to the bottom under the wave. The finer particles (-600 mesh and smaller) drop into a Skin Effect area. That area is directly against the skin of the table top.

The water in this area does not move with the flowing water but rather sits almost still. The motion of the table causes this “Skin Effect” water to move in the opposite direction of the flow. Thus the fine gold or mineral moves ‘up’ the table and falls into the concentrate trough.

The gold and/or concentrates can then be washed automatically into a concentrate bucket or a security safe, or vacuumed off the table. Ore should be classified according to size for efficient results.

* Gravity separation

* Separates material to 5 microns

* Recover metal values lost by other methods

* Simple operation – Adjustable water flow, adjustable bump, adjustable tilt

* The Micron Mill Wave Table can be fed from an overhead tank, slurry fed by conveyor belts, or by pipe, depending on your setup requirements.

Or so it seems at first.

Actually, MOST of those pages have nothing to do with the Micron Mill Wave Table that we are talking about here at GoldWaveTable.com. Not even remotely close. There’s audio products, furniture, massage tables, and tons more stuff that we don’t want.

Have you ever been frustrated by finding TOO MANY IRRELEVANT results when you use the search engines?

Me too. You scan through the first few pages of results and then you give up.

But here’s good news. You can shortcut your way to exactly what you were looking for. Let me show you…

How to find your kind of wave tables in Google:

(or whatever it is you are searching for – and this method should work similarly in most other search engines, though I confess I haven’t tested it elsewhere).

The trick to speed up your search is to eliminate the irrelevant sites from the search engine results pages BY USING A MINUS SIGN to remove all the pages with those unwanted words on them.

But first of all, put the term you want inside double quote marks. Like this:

“wave tables”

This will eliminate all the pages that have the words wave and tables separated. Such as a page that says “the waiter gave him a nod and a wave then continued to clear the tables”.

Now let’s add some minus sign terms. Like this:

-music

Why music? Because it a key word in the first result — which is a Wikipedia page about the musical kind of wave tables. Adding -music has cut my search results down at a mere 51,600 pages. Still a bit many, eh.

I scan down the first page and see an entry about massage. Yep, massage tables are also irrelevant so I add:

-massage

Each time you add another word with the minus sign immediately before it (no blank space), you cut down on the number of results you get.

So here’s what I finished up in my search box with after adding a load of “minus words”, one at a time:

“wave table” -sound -midi -massage -wavetable -studio -audio -lamp -records -Baccarat -vesper -cloth -wists -desk -french -fountain -tablemat -coastal -clock

This has cut back the original 6 million results to a mere 10,600 but that’s still way too many so it’s time for a new search strategy. Let me tell you about it.

Advanced search:

Right next to the “Search” button at the top of the page, Google has a tiny link marked “Advanced Search”. Click it. This will carry over all our minus words and search terms but additionally it allows us to tell it to find pages that include one or more of certain words we specify.

How do we specify? Use the section labeled “one or more of these words:”

In the 3 boxes it provides, I typed minerals metallurgy mining (one word in each field) because our particular type of wave tables are found in the context of these words.

BINGO. Now we have only 219 pages listed by Google. Great.

Here is the final search string (what I had in the search box):

mineral OR metallurgy OR mining “wave table” -sound -midi -massage -wavetable -studio -audio -lamp -records -Baccarat -vesper -cloth -wists -desk -french -fountain -tablemat -coastal -clock

And in case you’re weird like me and are interested in this sort of thing, here is the URL for the Google search results page from that search:

http://www.google.com.au/search?q=+mineral+OR+metallurgy+OR+mining
+%22wave+table%22+-sound+-midi+-massage+-wavetable+-studio+-audio
+-lamp+-records+-Baccarat+-vesper+-cloth+-wists+-desk+-french
+-fountain+-tablemat+-coastal+-clock&num=20&hl=en&lr=&client=
firefox-a&rls=com.google:en-US:official&as_qdr=all&start=0&sa=N

The result? –> We have found the EXACT thing we were looking for.

In hindsight

Sometimes you only know the best and fastest way to do things after you’ve done it the long way first.

This search would have been much faster if I’d done it right from the start. In other words, if I’d used the “double quotes” method plus the words mining OR mineral. Like this:

“wave table” mining OR mineral

That search takes us directly to pages about wave tables that also include the word mining or mineral.

BINGO. Hole in one.

If you click that link, you’ll see that our site is listed at the top of the results. As the webmaster around here, I did a little happy dance about that, let me tell you!

“The Wave Table is proving itself superior to almost any other wet gravity device and certainly superior to the traditional shaking tables.

The manner in which the valuable mineral reports on the Wave Table is one of its great advantages. As the photos show, gold reports transversely on the Wave Table deck.

Other concentrating tables have their concentrates reporting longitudinally. Having the concentrates reporting transversely permits the operator to set the Wave Table to ‘hold’ the gold, or other mineral concentrate, in a stationary position on the deck. This allows the gold to accumulate until the operator either wet vacuums it directly off the Wave Table or adjusts the unit to continually discharge the concentrates into a holding container.

The other great advantage of the Wave Table is its ability to recover the ultra fine mineral particles. For example with gold, it is not that difficult to recover the coarse particles. The problem has always been dealing with the sub 50 micron sized fraction. Now these valuable ultra fine mineral particles can be recovered at a high recovery rate on the Wave Table.”
