How it Works

The semi-continuous (batch) Knelson Concentrator (KC) has revolutionized the gravity recovery of precious metals from both hard-rock milling operations and alluvial mining plants worldwide.

The continuous Knelson Concentrator (CVD) utilizes the same widely proven fluid bed enhanced gravity separation technology as the semi-continuous Knelson Concentrator. The key difference is the method in which the concentrates are collected and discharged. Learn more about the continuous-type Knelson Concentrator.

The ConSep ACACIA Reactor is a high efficiency leaching system, exclusively designed to handle the high-grade concentrates produced by Knelson Concentrators. The system is designed to maximize gold recovery from gravity concentrates and provide numerous process advantages over a conventional gold room.
