ABSTRACT:
A process for removing S and Fe and to reclaim V, Ni and Co from coal or oil and their derivatives or from minerals. The process is based upon an oxidative extraction performed with hypochlorous acid (HC10) whose oxidizing power is generated and regulated "in situ". The process is particularly applicable to the recovery of V from residual flexi-coke and to the recovery of Ni from coal.
