FLSMIDTH KNELSON is the world leader in the development, design manufacturing and supply of Knelson Gravity Concentration Technology for the Global Mining & Minerals Processing Industry.A full range of products and services are available including gravity amenability testing, flowsheet development, circuit engineering, Knelson Gold Concentrators and supply of Turnkey Gravity Circuits worldwide.

The Knelson Gold Concentrators comes in a variety of models and sizes and are all known for highly efficient recovery of gold, fine gold and recovery of other precious metals and will be suited for any hard rock or alluvial mining operation.

Before moving on we would like to invite you to read the Ten Do’s and Don’ts of Gold Gravity Recovery. This document is written by Mr. André Laplante, McGill University, Canada. Internationally renowned leader in mineral processing and for his extensive knowledge within the area of gravity gold recovery.

He is also credited for developing and making the Gravity Recoverable Test (GRG-Test) a widely accepted industry standard procedure for testing. Once you have read the document you should be ready to see why Knelson is the right choice when it comes to optimizing your gold recovery rates. 

The KNELSON GOLD CONCENTRATOR model range includes: 

Quantum Series (QS)  Batch Concentrator Maximum Feed Capacity from 150 to 400 tonnes/ hr solids. 

Extended Duty  (XD) Batch Concentrator Maximum Feed Capacity from 80 to 1.000 tonnes/ hr solids. 

Centre Discharge (CD) Batch Concentrator Maximum Feed Capacity from 8 to 100 tonnes/ hr solids. 

Manual Discharge (MD) Batch Concentrator Maximum Feed Capacity from 0 to 1.500 lbs/ hr feed capacity (Used by metallurgical Schools, laboratories, exploration, pilot projects and various test works). 

Patented Knelson Continous Variable-Discharge (CVD) Concentrator Maximum Feed Capacity from 2 to 300 tonnes/ hr solids. 

FLSmidth Knelson supports the entire range of products with exchange and refurbishment programs as well as spare parts and services packages. 

The first prototype of the Knelson concentrator was introduced by founder Byron Knelson in 1978. Today the mining industry has recognised  FLSmidth Knelson as the world leader and most effective gold concentrator with respect to:


The FLSmidth Knelson concentrator has well documented high recoveries! 


The FLSmidth Knelson concentrator has well documented high-grade concentrate recovery!


The process requires no harmful chemicals such as mercury.Cleaner mining better for the environment and yields better results.
