G&W Base Minerals is the leading supplier of specialised industrial minerals in South Africa and has been servicing the needs of both local and overseas customers for over 50 years.
We operate 7 mines in South Africa and other products are bought in from both local and international suppliers. These are processed at our Wadeville plant and distributed directly to our customers.
A fully integrated traceable quality assurance programme is in operation to monitor every stage of the supply chain process - right from raw material acceptance through to delivery of the final product and has resulted in G&W Base receiving the coveted ISO 9001:2000 certification.
Our research and development involves continuous improvement of product performance, process improvements and product customisation to supply our products to our customer’s exact needs.
We seek to increase our market share by the continuous improvement of our products and customer service and by providing the leadership, resources and training necessary to create an environment in which every member of the company can contribute towards our continuing success.
