The densest, hardest shell carbon available for CIP/CIL tanks.
Extremely tough carbon designed to extract precious gold from liquid mining mixtures.
The densest, hardest shell carbon available for CIP/CIL tanks.
Large enough to be screened out of the pulp, not lost with it.
Resists attrition so gold isn't lost as fine dust.
If the carbon breaks, you lose your gold.
The carbon doesn't just sit in a quiet filter. It is thrown into massive tanks of churning mud, pumped through pipes, and blasted with heat to get the gold back off. If the carbon crumbles into dust during this harsh process, that gold-covered dust washes out into the waste pile. This is why we use premium coconut shell carbon—it is the toughest natural carbon available.
97–99
% Hardness
Mining carbon must be exceptionally hard so it does not turn into dust and take the gold with it.
The carbon is one stage in a train, not the whole of it.
At the mine, chemicals are used to dissolve the solid gold out of the crushed rock into a liquid solution.
Our tough coconut carbon is added to the mixture. It acts like a sponge, pulling the dissolved gold out of the liquid and locking it inside the carbon.
The gold-loaded carbon is screened out of the mud. Because our carbon is tough, the pieces stay large and are easy to catch on the screens.
The carbon is washed with hot chemicals to release the gold. The carbon is then baked in a furnace to clean it, so it can be reused again.
The grades that fit gold recovery — and what each is good at.
Premium Coconut Shell
The carbon is mixed directly into a thick, muddy slurry of crushed rock and chemicals. It absorbs the gold right out of the mud, and is then screened out to harvest the gold.
Premium Coconut Shell
Instead of muddy slurry, clear gold-bearing liquid is pumped upward through tall towers filled with this carbon.
What each property actually governs once the bed is running.
The most critical number. A score of 98% or higher ensures the carbon won't break into dust and lose your gold.
Large enough pieces so they don't slip through the mining screens and get lost in the waste.
Proves the carbon has a massive amount of microscopic pores ready to absorb the gold.
We strictly limit flat, flaky pieces of carbon, because flat pieces can slip through the screens and be lost.
It is the hardest natural carbon available. In mining, soft carbon crumbles into dust, and any gold trapped in that dust is lost forever. Coconut carbon is tough enough to survive.
It is the physical size of the carbon pieces. They must be perfectly sized so they are large enough to be caught by the mine's screens, but small enough to absorb gold quickly.
Yes. After the gold is removed, the carbon is baked in an incredibly hot kiln (furnace) to burn off dirt and reopen the pores. It can then be put right back into the gold tanks.
