摘要： The present disclosure concerns a process for the recovery of valuable metals from polymetallic nodules. A two-stage process using SO2 in an acidic aqueous media is disclosed. In a first step, performed in mildly acidic conditions, Mn, Ni, and Co are dissolved; in a second, more acidic step, Cu is dissolved. Under these conditions, the leachate of the first step contains most of the Mn, Ni, and Co, while being nearly Cu-free. The Ni and Co are precipitated as sulfides; the Mn can be recovered as sulfate by crystallization. Cu, which is leached in the second step, is secretively precipitated, also as sulfide.

摘要： The present disclosure concerns the production of precursor compounds for lithium battery cathodes.
Batteries or their scrap are smelted in reducing conditions, thereby forming an alloy suitable for further hydrometallurgical refining, and a slag. The alloy is leached in acidic conditions, producing a Ni- and Co-bearing solution, which is refined.
The refining steps are greatly simplified as most elements susceptible to interfere with the refining steps concentrate in the slag. Metals such as Co, Ni and Mn are then precipitated from the solution, forming a suitable starting product for the synthesis of new battery precursor compounds.

摘要： A process is disclosed for the recovery of valuable metals from oxidic ores, in particular from polymetallic nodules. The process is suitable for the recovery of Cu, Co, Ni, Fe, and Mn, which are the main metals of interest in such polymetallic nodules. The present process is, among others, characterized by the handling of Fe, which is dissolved and kept in solution until the step of crystallization rather than removed at an earlier stage. A mixed Mn—Fe residue is obtained, which, after thermal treatment, provides a Mn—Fe oxide that is suitable for the steel or for the manganese industry. Excellent Cu, Co and Ni yields are obtained, while Fe is leached and valorized together with Mn.
