Zinchem is the largest producer of zinc oxide, zinc dust and sulphates in Africa and supplies local and international markets. Main customers are the gold mining, paint and rubber industries.
Zinc dust is crucial in gold precipitation and finds application in rust-inhibiting zinc-rich paints and coatings. Zinc oxide is used in the manufacture of all rubber products, and a major market is the tyre industry. Zinc-based chemicals are also used in the agricultural industry in fertilisers and animal-feed additives.
Zinchem was established in 1946 and is based on an eight hectare site in Benoni on the outskirts of Johannesburg. As an ISO 9002-accredited supplier, Zinchem produces high-quality materials suitable for markets worldwide. New product development is critical to the company's growth.
The company adds value by producing high-quality products from primary and secondary materials and is committed to an environmental awareness programme, including reduction of emissions and the sale of all its plant byproducts.
Technology is important to Zinchem as it continually upgrades existing plant and production techniques to ensure that the company remains a competitive, efficient supplier of high-quality products.
