The HPAL Process :: Total Materia Article

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.

Nickel processing Extraction and refining Britannica

Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel
