Extreme Tropical Humidity & Storage

Regions like Chocó and the Andean slopes experience some of the highest rainfall globally. Standard chemical packaging fails under high humidity, causing Sodium cyanide to rapidly hydrolyze and degrade before it even reaches the leaching vats.

Refractory Sulfides (Cyanicides)

The Segovia-Remedios belt produces ores rich in sulfides (pyrite, sphalerite). These act as severe oxygen and cyanide scavengers, rapidly depleting weak reagents and drastically reducing overall gold dissolution rates in CIL tanks.

Stringent ANLA Environmental Scrutiny

As the Colombian government fiercely cracks down on illegal mining and toxic discharge, large commercial plants face immense permitting pressure. Transporting and detoxifying traditional Class 6.1 cyanide requires heavy security escorts and exorbitant compliance OPEX.

1. How does AuCyan™ maintain stability in Colombia's extremely humid, high-rainfall regions?

Sodium cyanide is highly hygroscopic; exposure to tropical humidity in regions like Chocó or Antioquia can cause it to absorb moisture, hydrolyze, and lose active CN⁻ strength before use. To combat this, AuCyan™ (≥98.3%) is manufactured with a remarkably low moisture content (≤0.3%) and is packaged in highly secure, UN-certified 50kg steel drums or 1,000kg reinforced wooden boxes. Crucially, every package contains a thick, heat-sealed inner polyethylene (PE) liner, ensuring the briquettes remain 100% dry and stable during prolonged storage at the mine site.

2. Which Colombian maritime ports do you utilize for CIF deliveries?

To ensure optimal inland routing for our mining partners, we offer comprehensive maritime shipping to both the Pacific and Caribbean coasts. Under CIF terms, we regularly dispatch ocean containers to the Seranan'i Buenaventura (ideal for western and central Andean operations) and the Port of Cartagena / Barranquilla (for northern operations). Once the cargo is cleared at the destination port, the client's appointed local logistics provider manages the inland trucking to the specific mine site.

3. Does the ANLA (National Authority of Environmental Licenses) permit the use of AuLeach™?

Eny. Satria Mpanadio Volamena AuLeach™ (GDA) is globally certified as a Tsy mampidi-doza chemical substance (unlike DG Class 6.1 Sodium Cyanide), it aligns perfectly with the stringent environmental conservation mandates enforced by the ANLA and regional autonomous corporations (CARs). Utilizing AuLeach™ vastly simplifies the environmental licensing process for new concessions, eliminates the requirement for heavily armed inland transport escorts, and significantly lowers the toxicity of your tailings discharge.

4. Why is a ≥99% hardness rating critical for Karbona navitrina in Colombian CIL plants?

In modern Carbon-in-Leach (CIL) plants, the ore slurry is subjected to continuous, high-shear mechanical agitation. If the activated carbon is soft or poorly activated, the impeller blades will grind the carbon granules into microscopic dust. This fine carbon—now loaded with your extracted gold—will pass through the retaining screens and be permanently lost in the tailings pond. AuCarb™ provides a guaranteed ball-pan hardness of ≥99%, ensuring immense structural integrity and maximizing your ultimate gold yield.

5. Are there any capital expenditure (CAPEX) costs to switch from Cyanide to AuLeach™?

Absolutely zero. AuLeach™ is engineered as a 100% direct drop-in replacement for Sodium cyanide. Colombian plant managers do not need to purchase new leaching tanks, alter their Heap leach drip irrigation systems, or modify their carbon elution and electrowinning circuits. You simply substitute the cyanide with AuLeach™ in your dosing regime, utilizing standard hydrated lime to maintain the optimal pH level (usually between 10.5 and 11.5).

6. How does AuCyan™ perform against the refractory sulfide ores found in Segovia?

Ores from regions like the Segovia-Remedios belt often contain refractory sulfides (such as pyrite and sphalerite) which consume large amounts of oxygen and reagent. Sianida Sodium AuCyan™ delivers an ultra-high purity of ≥98.3%, ensuring an overwhelming concentration of free CN⁻ ions. This aggressive formulation rapidly penetrates the ore matrix, preventing the base metals from entirely depleting the cyanide before the gold can be fully dissolved, thus securing high recovery rates.

7. Do you provide railway transport for inland deliveries in South America?

No. Due to severe international safety regulations governing the movement of hazardous chemicals and the logistical complexities of the Andean geography, we strictly prohibit the use of international railway transport for our exports. We secure our supply chain exclusively via maritime ocean container shipping.

8. What is the Minimum Order Quantity (MOQ) for exporting mining chemicals to Colombia?

To guarantee factory-direct pricing, protect the integrity of the chemical packaging, and optimize maritime freight costs across the Pacific, our strict MOQ is 1x20' FCL (Entana feno ao anaty fitoeran-javatra). This policy applies universally to AuCyan™, AuCarb™, and AuLeach™. Depending on the product and packaging type, a single 20-foot container typically accommodates between 10 to 20 metric tons of material.
