Gold mining
Extruded NORIT RO grades are produced in our proprietary manufacturing process, resulting in a homogeneous product with a dedicated micro-, meso-, and macropore structure. In gold recovery this brings: Fast gold adsorption: capturing the gold cyanide quickly for optimal yield and security of operation Very high abrasion resistence (and no platelets): minimizing carbon fines losses …

Who is now collecting micron gold from rivers/other waters?
Even spent geothermal surface waters have only the tiniest part per billion traces of gold. Sea water has the same kind of tiny traces. normal fresh water has even far less gold. So recovering gold from water is a scam 99.99% of the time. As is often recommended, take an assay first. See how little gold is in your water.

Efficient gold-cyanide recovery from activated carbon by
Activated carbon, with its extensive network of pores, acts as an adsorbent. In gold mining, it traps gold cyanide complexes (Au (C N) 2 −)formed by leaching gold ore with cyanide solution (NaCN) . This adsorption process is primarily physical, involving weak attractive forces between the gold complex and the carbon surface .

Continuous Elution for Extraction of Gold from Carbon
Cooling water enters near the bottom of the vessel, cools the carbon and mostly exits with the carbon the balance- moving up the column with the eluate. The process uses similar eluates to those described by J.B. Zadra (1952), and uses higher temperatures and pressures to accelerate the rate of stripping as described by J.R. Ross (1973).

Gold Carbon-in-leach (CIL) Process
Gold CIL (Carbon in Leach) is a key part of gold extraction plants and is the preferred method for modern gold mining. The CIL process extracts gold from ore by simultaneously leaching and absorbing the gold onto activated carbon. It's particularly effective for ores with a grade of over 1g/t and large bearing ore volumes. CIL can also extract other minerals like silver, platinum, …
