Any Cyanide Process Designers here re: VG news release
Any Cyanide Process Designers here re: VG news releaseAny and all thoughts welcome.
Is VG is producing dore gold, no one has offically stated this is happening but SGS and Sensorex has some info in regards cyanide tailings cyanide water treatment.
If they are this is good move forward in remediation of the solution (pregnant or not) and getting some CoH.
SGS
"COST EFFECTIVENESS IS
CRITICAL
The cost of treating cyanide tailings
can be a significant percentage of
total operating costs, and unlike other
operating costs, yields no economic
“return”. It is therefore very important, for
both regulatory and economic reasons,
to select the correct process, and then
optimize the operating conditions to
minimize reagent dosages."

The Company and its third-party experts have determined that a modest irrigation
strategy to the areas of the HLF that were not impacted by the HLF incident is a safe water management
plan which will allow time for the Company to augment water treatment and discharge capacity at site
and will avoid direct discharge of untreated water to the environment.
Water Treatment
In order to establish capacity to safely discharge water in compliance with its Water Use License, the
Company has augmented its water treatment capacity on site. This includes the modification of piping,
the addition of tankage and the procurement and installation of a Reverse Osmosis (“RO”) plant which
will be used as a final stage of water treatment.
The existing infrastructure within the Mine Water Treatment Plant has been modified to allow inclusion
of a breakpoint alkaline chlorination process for cyanide destruction and metals precipitation. This
process utilizes sodium hypochlorite to oxidize cyanide with the resulting ammonia byproduct oxidized
by chlorine to nitrogen gas.
The Company has successfully commissioned its augmented water treatment capacity and anticipates the commencement of treated water discharge in the coming days

And Sensorex has a Waste Cyanide Treatment overview.
