Gold CIP (Carbon in Pulp) and Gold CIL (Carbon in Leach) are two of the most widely used cyanide gold extraction processes.
Both technologies are mature, reliable, and capable of achieving high gold recovery — when properly matched with the ore characteristics.

This page explains their core differences, application conditions, and selection logic from an engineering perspective.

Is CIL Always Cheaper Than CIP?

From a capital investment perspective:

CIL generally requires fewer tanks and lower initial cost

CIP requires additional adsorption tanks and higher upfront investment

However, from a long-term operating cost perspective:

CIP often performs better in:

Carbon consumption

Maintenance cost

Process stability

Reduced downtime risk

👉 Process selection should consider total lifecycle cost, not only initial investment.

Which Process Is Easier to Operate?

Although CIL appears simpler on flowsheets:

It is more sensitive to ore variability

Carbon performance is more easily affected

In real plant operation:

CIP is often easier to control, especially for complex ores

Separate control stages provide greater operational flexibility

Can CIP and CIL Achieve the Same Recovery Rate?

Yes — under the right conditions.

Comparable recovery can be achieved when:

The ore is suitable

Retention time is properly designed

Carbon management is effective

Process parameters are well controlled

👉 Design quality and operation discipline matter more than the process name.

How Do Engineers Select Between CIP and CIL?

In real projects, the decision is based on:

Ore type and gold occurrence

Leaching test results

Planned processing capacity

Site conditions and infrastructure

Investment budget and ROI expectations

📌 Without ore test data, process selection is not reliable.
