Can You Replace Sodium Cyanide Without Plant Modifications?

To answer your short question right away: yes, you actually can. 

You can switch out sodium cyanide (NaCN) and put Cnlite gold leaching reagent into your current gold processing plant today. If you run a carbon-in-pulp (CIP), carbon-in-leach (CIL), or standard agitation cyanidation setup, you do not need to tear down your tanks or re-engineer your whole layout.

Honestly, most plant engineers we talk to assume replacing cyanide means buying brand-new tanks or changing the whole circuit. But that is simply not true here. The physical workflow stays almost identical. The slurry still flows through the exact same agitation leach tanks, carbon columns, and pumps you already use every day.

Key Technical Considerations When Retrofitting Your Plant

When a mill manager or metallurgist looks at replacing hazardous sodium cyanide, two real concerns always come up first: will recovery drop, and will the monthly chemical bills skyrocket? We get it. Nobody wants to risk losing yield just to go green. Cnlite is made specifically as a drop-in replacement so you do not have to fight those headaches.

Equipment and Flowsheet Compatibility

Because Cnlite dissolves gold using a leach reaction similar to cyanide—just without the deadly toxicity—your existing plant hardware needs almost zero changes. Your leach agitators, air blowers, carbon screens, and elution skids keep doing what they already do.

In real operations, like our 500 t/d gold mine EPC project in Zimbabwe using gravity plus CIL, shifting reagents took no extra steel work. The crew simply fed the new reagent through the old chemical dosing system. That saved the owner months of downtime and hundreds of thousands of dollars in new hardware.

Reagent Dosage, pH Control, and Leaching Kinetics

You do need to tweak your day-to-day tank parameters slightly, but it is nothing complicated. Sodium cyanide usually forces you to run a super high pH level above 11.5, which eats up lime fast. With Cnlite, you keep your pulp pH right around 10.0 to 11.0.

You just add quicklime like usual to hold that pH, drop in Cnlite, and let the air blowers run. The leach time matches traditional sodium cyanide pretty closely, so your gold processing plant keeps running at full daily tonnage without bottlenecks.

Operational and Safety Benefits of Switching

Let's talk about the practical side of running a gold mine in places like Ghana, Tanzania, or the Philippines. Getting permits to haul and store sodium cyanide gets harder every year. Police escorts, dangerous chemical storage lockers, and constant safety checks cost real money and time.

Switching to a lower toxicity reagent cuts through that red tape fast. Your site safety manager sleeps better, your workers face far less danger around the mixing tanks, and your tailing pond detoxification costs go way down. You spend less cash on neutralizing chemicals before discharging waste.
