Process for removal of arsenic from sulfo-ore |
| abstract |
A process and apparatus for the removal of arsenic values from an ore concentrate includes the steps of leaching the concentrate with a solution which dissolves the arsenic, separating undissolved residue therefrom, acidifying the arsenic pregnant solution to precipitate arsenic and other mineral values as insoluble salts and treating the arsenic barren solution to regenerate sulfur and sodium values for recycle to the process. |
