Product Details

Gold CIL Production Line & Process Solution

The Gold CIL (Carbon-in-Leach) process is an advanced extraction technology where cyanide leaching and activated carbon adsorption are performed simultaneously.

OreSolution's CIL solution significantly improves gold recovery rates and lowers production costs. It is particularly suitable for high-grade gold ores and gold ores containing associated Silver and Copper.

Detailed Gold CIL Process Flow

Based on standard CIL technology, our process is optimized into four key stages:

Crushing & Grinding

Crushing: Adopts a "Two-stage One Closed-circuit" process using Jaw Crusher + Cone Crusher.
Grinding: A closed-circuit system with Ball Mill and Hydrocyclones ensures strict control of grinding fineness.

Leaching & Adsorption

Tank Setup: 9 tanks in series. First 2 for cyanidation, last 7 for simultaneous leaching & adsorption.
Carbon: Uses imported coconut shell activated carbon with counter-current flow.
Tech: Central Air-Inflation Tubes reduce energy consumption by 70%.

Desorption & Regeneration

High Temp & Pressure: Desorption at 150℃, 0.5MPa.
Efficiency: Time reduced to just 2-6 hours with a desorption rate of 99%.
Regeneration: Acid washing + Thermal regeneration ensures carbon recycling.

Recovery & Smelting

Electrolysis: Highly efficient recovery from pregnant solution.
Product: Cathodic gold purity reaches 99.9%.
Casting: Smelted into standard gold ingots.

Technical Deep Dive: Why Choose CIL?

Comparison: CIL vs. CIP Process

Many clients ask about the difference between CIL and CIP. While both use activated carbon, their flowcharts differ significantly.

Feature	CIL (Carbon-in-Leach)	CIP (Carbon-in-Pulp)
Process Order	Leaching & Adsorption happen simultaneously.	Leaching first, then Adsorption separately.
Investment Cost	Lower (Fewer tanks needed).	Higher.
Preg-Robbing	Effective. Carbon grabs gold before ore re-absorbs it.	Not suitable.

1. Significant Economic Benefits

Saves 66% investment compared to traditional CCD processes. Reduces capital backlog and accelerates turnover.

2. High Efficiency

Simultaneous leaching and adsorption. Central aeration saves 70% energy. Rapid desorption boosts efficiency.

3. Eco-Friendly & Smart

Closed system design, high carbon recycling rate, and automated digital monitoring.

Key Equipment Configuration

System	Core Equipment	Technical Features
Crushing	Hydraulic Cone Crusher	Laminar crushing principle
Grinding	Overflow Ball Mill	Energy saving 30% design
Leaching	Cyanide Leaching Tank	Centralized Aeration System
Desorption	Desorption Column	Rapid Desorption (2-6h)
Electrolysis	Electrolysis Cell	High efficiency deposition

Frequently Asked Questions (FAQ)

Q: What types of ore are suitable for your CIL process?

A: Our CIL solution is specifically recommended for High-grade Gold Ore and Gold Ore containing associated Silver and Copper. It is also the best choice for ores with "preg-robbing" carbon.

Q: How about the investment benefits?

A: The larger the processing capacity, the more significant the economic benefits. Our clients typically see a short payback period due to lower initial investment (saving up to 66% vs CCD) and higher recovery rates.
