Alluvial Gold Mining: One Gold Capture System component I use: Coir-the perfect gold catcher from Coconuts?

It certainly is one of the best for performance, availability and price!

Gold this size and shape is easy to capture & catch with almost any sluice box insert (miners moss/nomad, indoor/outdoor carpet, rubber mats….etc :


And this shape & size is also easy to capture and trap:


But this gold size and shape below is another story, especially when using high water volumes to process 20-30t/hr of raw river material with dredges & hand feeds. And that is the key here, capture/catch the fine, flat & flake hydraulic floating gold that is usually lost and sacrificed by most artisan digger/panners (crude methods) & commercial operations (marginal gold capture systems that don’t work well with high water volumes) alike, just test their tailings to verify the fine gold they lose. This is what I’m talking about:

Coir rubber backed door/welcome mats:

I use Coir, a natural fiber made from coconut husks; you won’t find this on the internet or from any gold equipment supply company in the world. They don’t know about it, as it is a GoldMasterAfrica exclusive technique; 1 of 8 components, that work for me, within my proprietary Gold Capture System designs, techniques and methods, highlighted in my e-book:

Book 1: Gold Capture Methods for Commercial Production

Coir rubber backed welcome/door mats are all over Africa and raw coir comes from India & Sri Lanka (90% of world production). The price & performance of these mats are exceptional. I buy the mats for about $5-6usd anywhere in Africa. They are full of fiber, mini fiber riffles, trapping pockets and miniature rubber drop riffles for getting the fine, flat & flake gold.


Coir acts like a Goalkeeper/Defender in Football for me, it is my back up & safety net to my primary system, it doesn’t let any gold get out! More on Coir:

“The coir fiber is relatively waterproof, and is one of the few natural fibers resistant to damage by saltwater. Fresh water is used to process brown coir, while seawater and fresh water are both used in the production of white coir.”[5]

This is what the mats look like:

Mats & carpet in general do not concentrate free gold; they catch, capture and trap it from concentrating systems such as: Hungarian riffles-all styles & shapes, drop riffles, drop ramp riffles, raised wire mesh, (dampers & crash plates)………etc.) that create drop & reverse vortex low pressure zones.

Jute rope door mats are a close 2nd:

“Jute is a long, soft, shiny vegetable fibre that can be spun into coarse, strong threads.”

I get this jute rope mat with no rubber backing (you can see through it) for different soil types (such as fine clay or silt) as a different trapping option. I place it over low V height rubber mats. It’s also a great gold catcher comparable to a Coir mat. It has many small riffle design variations and pockets built in, found all over Africa. All my configurations can be made from local country materials. See photos:

Just look at all those Jute fibers that catch & trap gold:


The fine gold drops through it onto the rubber V matting below.

How I use these mats and where I place them within my sluice boxes by my exclusive methods, are given in extensive detail along with other components I use, that compliment each other to catch & capture all the gold, are detailed in my e-book above.
