Metallic Ore Dressing Agent

1. Low toxicity & environmental protection
The product is non-flammable, non-explosive, has no oxidant hazard, no radioactive hazard, is low-toxic, belongs to ordinary chemical products, and is an environmentally safe gold beneficiation agent.

2. Stable performance
Reduces the interference of harmful substances such as arsenic AS and sulfur S, has strong applicability, and is suitable for heap leaching, pool leaching, and carbon slurry process production of oxidized gold and silver mines.

3. High leaching rate
Effectively leaches gold ions, which is higher and faster than using sodium cyanide, and improves the recovery rate. Heap leaching production has a shorter cycle than using sodium cyanide (can be shortened by about 30%), and faster recovery.

4. Lower cost
Reduces the costs of procurement, transportation, warehousing, storage, use, safety, and environmental protection facilities, etc. The production process is consistent with the method of using sodium cyanide, which is easy to use and promote.

The environmentally friendly gold leaching agent operates similarly to the sodium cyanide process, with the flexibility to recycle depleted solution while using activated carbon (or zinc powder/zinc wire/resin) for gold adsorption. Optimal leaching efficiency is achieved at ambient temperatures above 10°C, and the agent can be applied alongside sodium cyanide if needed.

Heap/Pool Leaching

Prepare a 0.03–0.1% solution with clean water for spraying or immersion.

Agitation Leaching

Use a 10–15% concentrated solution or add the solid agent directly into the mixing tank.

Maintain reagent concentration in the slurry between 0.03–0.1%.

1. Pre-Treatment Adjustment
Adjust ore heap/pulp alkalinity using lime or other alkaline agents (target pH: 11–12).

2. Leaching Process

• Heap/Pool Leaching: Prepare solution at the optimal concentration (determined via testing) for spraying/soaking.
• Agitation Leaching: Follow test-derived parameters (slurry density, gold concentration, leaching duration).

3. Concentration Monitoring

Regularly check the leaching agent concentration and replenish if depleted.

4. Customized Dosage Optimization

Adjust agent dosage based on ore composition and pH, guided by small-scale tests and the recommended detection method.
