titleOfInvention |
Process for stabilisation of an arsenic solution comprising thiosulfates |
abstract |
A process is provided for separation of at least one metal sulfide from a mixed sulfide concentrate. The process may comprise: subjecting the mixed sulfide concentrate to flotation in which at least one sulfide comprising antimony, arsenic and a first metal is floated and at least one sulfide comprising a second metal is depressed. The flotation yields a first metal concentrate having the at least one sulfide comprising antimony, arsenic and the first metal and a second metal concentrate having the at least one sulfide comprising the second metal. The first metal concentrate is leached to yield a further concentrate and a leach solution. The further concentrate comprises the first metal and the leach solution comprises soluble antimony and soluble arsenic. The process may further comprise oxidizing the leach solution to yield an antimony precipitate and an arsenic solution, and forming a stable arsenic compound from the arsenic solution. |
