Last year proudly marked mineral concentration specialist GCA’s 21st year as agents for FLSmidth Knelson concentrators through an association that began in 1997 and thereafter many successful installations of Knelson concentrators in Africa.
GCA has also been instrumental in most of the +300 large-scale Knelson concentrator installations on the African continent.

GCA’s strategic objective is to remain African market leaders in gravity recovery solutions and to provide enhanced technological advancements in equipment, process and mineral recovery solutions to the African mining industry.
In addition to its distribution agreement for Knelson Concentrators, GCA has had a +15-year agreement in place (for Africa) to distribute the Consep Acacia Reactor, and has recently added new products to complement its technology range.
Filtaworx, a range of fully automated, self-cleaning industrial water filters is one of the newest products, providing advanced technology in particulate filtration.
The filters have a number of useful applications, in multiple industries, and are particularly helpful in African areas that have poor quality water.
GCA has provided the Filtaworx filters to clean plant process water, fluidisation water cleaning for the Knelson concentrators, and for gland service water.
The easily replaceable screens range from 50 to 800 microns, and the extensive range of filters can handle between 25 and 900 cubic meters of water per hour in a single unit.
“As a leader in gravity concentration, GCA aims to provide the latest technology to its clients to optimise their process, improve their equipment operation and to provide sustainable low maintenance solutions,” says GCA MD Martin Meyer.
In recent years GCA has focused on customer excellence and managed to assist clients to improve their process, minimise their downtime, and increase their recoveries.
“One of our recent successes saw us assist one of our clients to improve their gravity recoverable gold from 9 – 10% in 2016 to an average of 20% in recent months.”
GCA prides itself on customer satisfaction, and its staff is driven by its customers’ success.
The company operates a registered Knelson test facility and will conduct or manage mineral test work on behalf of clients in order to better consult on concentration technology requirements.
GCA’s spares department efficiently handles enquiries from throughout the African continent, and its support personnel travel from Guinea to Cape Town, all over Africa (GCA) to ensure that its satisfied customers remain as happy as they were on the day when they first commissioned their equipment, to provide continual support and provide improvement solutions to optimize their processes.
