How does gold leaching agent compare to sodium cyanide in recovery rate?

CNLITE Gold Leaching Agent achieves 96–98% gold recovery — comparable to or better than sodium cyanide in most ore types. Independent SGS testing and real-world deployments across 1,000+ operations confirm this. For free-milling oxide ores, recovery rates are essentially identical.

Is gold leaching agent safer than cyanide?

Significantly safer. Sodium cyanide has an LD50 of 6.4 mg/kg (highly toxic). CNLITE Gold Leaching Agent has an LD50 greater than 5,000 mg/kg — classified as non-toxic. It produces no hydrogen cyanide gas and requires no cyanide destruction in tailings.

Do I need to change my equipment to switch from cyanide to CNLITE?

No. CNLITE Gold Leaching Agent is a true drop-in replacement. It operates at the same pH range, dissolved oxygen levels, and pulp densities as cyanide. Your existing CIL, CIP, heap leach, or agitation leach circuit requires no modification.

Is CNLITE Gold Leaching Agent available in stock in Zimbabwe?

Yes — CNLITE Africa holds stock at their Harare warehouse year-round. Orders can typically be fulfilled within 1–3 business days for Zimbabwe-based operations.

What ore types work best with CNLITE Gold Leaching Agent?

CNLITE Gold Leaching Agent performs best on free-milling oxide gold ores and alluvial/placer gold, achieving 96–98% recovery. It also performs well on partially oxidised sulphide ores (88–94%) and low-sulphide ores (85–93%).

Can CNLITE Gold Leaching Agent be used for small-scale and artisanal mining?

Yes — it is particularly well-suited for small-scale and artisanal miners. The non-toxic nature eliminates the safety risks associated with cyanide handling. It works in simple agitation leach setups with basic equipment.

Is gold leaching agent more expensive than cyanide?

The reagent cost per tonne of ore is slightly higher than sodium cyanide in some cases. However, total operating cost is often lower when factoring in eliminated cyanide destruction costs, reduced environmental compliance costs, lower insurance premiums, and no cyanide storage infrastructure. Most operations see a net cost saving within 6–12 months.

What happens to CNLITE Gold Leaching Agent in tailings?

Unlike cyanide, CNLITE Gold Leaching Agent does not require a dedicated cyanide destruction step before tailings disposal. The reagent is biodegradable and breaks down naturally, eliminating the cost and complexity of SO₂/air or hydrogen peroxide cyanide destruction circuits.

What pH level is required for CNLITE Gold Leaching Agent?

CNLITE Gold Leaching Agent operates optimally at pH 9.0–11.5, with the sweet spot at pH 10.0–11.0 for most ore types. This is the same pH range used in conventional cyanide leaching, so your existing lime dosing system requires no changes.
