Abstract
A process for separating molybdenum values from sea nodules which includes sulfation of the sea nodules, volatilization of the molybdenum values from the sea nodules and collection of the volatile molybdenum values.
Claims8
A process for recovery of molybdenum values from ferromanganese sea nodule ores which comprises the steps of:
- (a) sulfating the nodule ore with sulfur dioxide in the presence of oxygen;
- (b) volatilizing the molybdenum values from the sulfated ore;
- and
- (c) condensing the volatilized molybdenum values from step (b) and collecting said molybdenum values in their thus condensed form.
1 more element
A process for recovery of molybdenum values from ferromanganese sea nodule ores which comprises the steps of:
- (a) contacting the nodule ore in substantially dry state with sulfur dioxide in the presence of oxygen under substantially dry conditions to convert metal values thereof excepting iron values to water-soluble salts;
- (b) volatilizing the molybdenum values from the so-contacted ore of step (a);
- and
- (c) condensing the volatilized molybdenum values from step (b) and collecting said molybdenum values in their thus condensed form.
1 more element
A process for recovery of molybdenum values from ferromanganese sea nodule ores which comprises the steps of:
- (a) contacting the nodule ore in substantially dry, finely-divided state with sulfur dioxide in the presence of oxygen under substantially dry conditions and at an elevated temperature sufficient to volatilize the molybdenum values of said ore;
- and
- (b) condensing the molybdenum values volatilized from step (a) and collecting said molybdenum values in their thus condensed form.
