On the other hand, the HPAL process is used more commonly for limonitic ores with high iron, containing low magnesium and silica. The process starts with crushing, followed by screening. In this step, it is commonly evaluated if the ore can be concentrated (beneficiated) by screening, where the enriched-silica fraction is separated from the ore.
