What is Sodium Cyanide used for?

Sodium Cyanide is commonly used in the mining industry for extracting gold from ores.

How can I optimize the use of chemicals in ore processing?

Optimizing the use of chemicals in ore processing involves several strategies to enhance efficiency and cost-effectiveness:

Are there specific regulations for the use of mining chemicals?

Yes, the use of mining chemicals is subject to various regulations that govern their production, use, storage, and disposal. These regulations are designed to protect human health and the environment. Key regulatory aspects include:

What is a settling agent, and how does it work in mining?

A settling agent, also known as a flocculant, is a chemical used to accelerate the settling of suspended particles in a liquid. In the context of mining, settling agents are crucial for improving the efficiency of ore processing and tailings management.

How do I store Sodium Cyanide safely?

Sodium Cyanide should be stored in a cool, dry place, away from incompatible materials and in accordance with safety guidelines.

United Chemical AuCarb AC50 Series:

Premium Coconut Shell Activated Carbon

The "Profit Guardian" for Gold Recovery. Engineered for Maximum Adsorption, Zero-Waste Hardness, and Superior CIL/CIP Performance.

A.A.R.L ASTM Standard ISO Certified

Why AuCarb AC50 is the Industry Choice?

In modern gold recovery (CIP/CIL), while Sodium Cyanide determines how much gold is dissolved, Activated Carbon determines how much gold is actually kept. AuCarb AC50 is not just a filter medium; it is a high-performance catalyst for your mine's profitability.

Sourced from high-altitude, aged Coconut Shells in Southeast Asia and processed via advanced steam activation, it solves the critical pain points of "Carbon loss, low loading, and attrition".

Critical Performance Benchmarks: Why It Matters?

Ball-Pan Hardness

AuCarb: ≥ 99% Industry: 95%-97%

Why it matters: In CIP/CIL tanks, carbon particles are subjected to violent agitation. A 99% hardness ensures the carbon maintains its integrity, preventing the formation of loaded "carbon fines" that escape through screens—effectively locking your gold in the circuit rather than letting it bleed into tailings.

A.A.R.L

AuCarb: ≤ 1.5% Industry: ≤ 3.0%

Why it matters: This measures long-term durability. By controlling the attrition rate at an elite 1.5%, you reduce annual carbon consumption by over 20%. This directly cuts your operational costs and minimizes the risk of gold being carried away by fine carbon particles.

K-Value (Adsorption Kinetics)

AuCarb: ≥ 26 kg/t Industry: 20-22 kg/t

Why it matters: Time is money in mining. A K-value of ≥26 kg/t means our carbon captures gold ions faster and more aggressively. This allows for higher slurry flow rates and ensures peak recovery even when treating high-grade ores or fluctuating feed grades.

R-Value (Adsorption Equilibrium)

AuCarb: ≥ 50% Industry: 35-45%

Why it matters: The R-value reflects adsorption efficiency in dynamic conditions. High R-values mean peak equilibrium is reached sooner, ensuring that low gold concentrations in the tail tanks are still efficiently captured, reducing the final tailing grade.

Total Ash Content

AuCarb: ≤ 3% Industry: 5% - 8%

Why it matters: Ash consists of inert impurities. Lower ash content means cleaner micropores and better performance after thermal reactivation. AuCarb can be regenerated more times with a 95%+ activity recovery, significantly extending the lifespan of each batch.

Platelet Content

AuCarb: ≤ 5% Industry: 8% - 10%

Why it matters: Flat "platelets" are the primary cause of inter-stage screen blinding (clogging). By keeping this ≤5%, we ensure consistent pulp flow through the circuit and prevent costly mechanical downtime for screen cleaning.

CTC & Butane Activity

AuCarb: ≥ 50% / 19.5% Iodine: ≥ 1100 mg/g

Why it matters: These parameters define the internal "storage capacity" of the carbon. A higher CTC/Iodine value means each grain can carry 15-20% more gold than standard products, allowing for higher loaded carbon grades and more efficient elution.

The Science of Superior Recovery: 3 Critical Benchmarks

1. The 99% Hardness Advantage

In high-agitation tanks, carbon collisions are violent. A 1% increase in attrition is not just lost carbon—it's gold-loaded carbon escaping into waste. AuCarb AC50 maintains peak structural integrity.

2. Kinetic Precision (K & R Values)

Our carbon achieves an R-Value (Adsorption Kinetics) ≥ 50%. This means gold ions are "locked" instantly, preventing losses even during surge flows or fluctuating ore grades.

3. Low Platelet Content (≤ 5%)

Uniform particle size (6x12 mesh) and low platelet levels ensure your inter-stage screens never clog, maintaining smooth pulp flow and preventing mechanical downtime.
