Fertiliser value of a limed gypsum by-product from mineral sands processing
The aim of the project was to measure the effectiveness of a pelletised by-product from mineral sands processing as a sulfur fertiliser in high rainfall sandy areas. The by-product is a neutralised acid effluent stream which precipitates to produce gypsum containing iron and manganese. The pelletised product has been given the name “Ironman gypsum” reflecting its major constituents.
