Hydrometallurgy is a cost effective way of extracting many metals from their ores including copper nickel uranium gold and zinc This involves crushing the ore and mixing with water to form a slurry which is reacted with sulphuric acid in an autoclave often at high temperatures >150°C and pressures 5 to 50 bar
