Abstract Precipitation of iron as hematite from acidic sulphate-chloride solutions was studied in a batch reactor at 150 °C. Several factors that either increase or decrease the extent of hematite precipitation (such as: sulphuric acid, chloride, seed, ferric iron, pre-neutralization, arsenic(V) and copper(II)) were studied. The presence of chloride in the solution increased the extent of hematite precipitation. The presence of low levels of arsenic(V) (
