The Direct Nickel ProcessTotal Materia Blog

Using nitric acid as a leaching agent the direct nickel process can treat all types of nickel ore and produces a single flow sheet for a number of final saleable products. As an atmospheric hydrometallurgical process the direct nickel process has an impressive recycle and return statistic meaning 95%+ of the nitric acid is reused, therefore
