Abstract
The present disclosure is related to carbonation and selective ammonia leaching for the recovery of minor metals.
Claims20
A method for extracting a target metal from a target metal-containing material, comprising:
- exposing the target metal-containing material to carbon dioxide such that the carbon dioxide reacts with target metal associated with the target metal-containing material to form a target metal carbonate, wherein the target metal is a transition metal;
- and
- leaching the target metal carbonate with a leaching agent to separate the target metal from the carbonate anion.
A method for extracting a target metal from a target metal-containing material, comprising:
- exposing the target metal-containing material to carbon dioxide such that the carbon dioxide reacts with target metal associated with the target metal-containing material to form a target metal carbonate, wherein the target metal is a transition metal;
- and
- leaching the target metal carbonate with a leaching agent to separate the target metal from the carbonate anion,
- wherein the leaching results in less than 10 wt % of the carbonate material from the target metal carbonate forming carbon dioxide.
