Adsorption of heavy metal ions on pyrrhotite

- Relatively large amounts of heay metal ions can be adsorbed on synthetic and natural pyrrhotite. The best result was obtained with Cu ions and pyrrhotite from Viscaria, with an adsorption of 4. 95 g Cu per kilogram of pyrrhotite. Good results have also been obtained with zinc and lead ions. A strongly oxidizing environment can have an adverse effect.

Comparative pilot scale tests with wet high intensity magnetic separators

Ingår i: Erzmetall. - 0044-2658. ; 35:6, s. 285-293
-

- The machines concerned were a Jones P71, a Boxmag-Rapid SHW 1 (since redesigned), a Readings 16-pole, a Krupp-Sol 24/14 and a Sala HGMS Mk II. The material used for test purposes was a mixture of hematite and quartzite, ground to a particle size distribution smaller than 500 mu m. The Fe assay of the material was 43. 7%. The variations in results due to capacity, magnetic field, energy consumption, matrix geometry and water consumption are reported.

Computer-assisted calculations of thermodynamic equilibria in the chalcopyrite-ethyl xanthate system

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Calculations show that thermodynamic data can be used to construct pulp chemistry models that satisfactorily describe events in mineral pulps. The usefulness of such models can be enhanced by the insertion of kinetic restrictions derived from analyses of mineral pulps from commercial-scale operations. A number of interesting findings concerning the chalcopyrite-ethyl xanthate system are demonstrated. As it is possible to calculate an operating line for any given flotation system, the calculation results can be compared at all times with practical experience and measurements of flotation processes.

Entphosphorung von hochphosphorhaltigen Eisenerzen durch saure Laugung
- 1981

Tidskriftsartikel (refereegranskat)abstract
- High phosphorous sinter fines are leached with hydrochloric or nitric acids to digest the phosphorous bearing apatite. Concentrates with less than 0. 05% P can be manufactured with acceptable losses of iron and acid consumption. The process will be viable if the phosphorus in the acid can be recovered as phosphoric acid.

Phosphate bonded fused alumina abrasive resistant material
- 1980

-
Tidskriftsartikel (refereegranskat)abstract
- Suitable particle size distribution and proportion of binder phase have been determined by measurements of mechanical strength and abrasion tests. A pump impeller was made. Comparative abrasion tests have shown that the abrasion resistance is better than that of a cast iron impeller and comparable to that of a rubber impeller.
