Electrooxidation of pentlandite in a carbonate solution
- 2004
-
Ingår i: Russian journal of electrochemistry. - 1023-1935 .- 1608-3342. ; 40:4, s. 420-423
-
Tidskriftsartikel (refereegranskat)abstract
- Electrooxidation of pentlandite in a carbonate solution involves the formation of surface sulfide minerals of nickel and iron of variable composition, sulfur, and iron and nickel hydroxides. In parallel, sulfide sulfur oxidizes in a narrow potential range to sulfate ions.

Mica behavior in aqueous solutions with pH 3-9
- 2005
-
Ingår i: Geochemistry International. - 0016-7029 .- 1556-1968. ; 43:7, s. 702-707
-
Tidskriftsartikel (refereegranskat)abstract
- Muscovite and phlogopite behavior was examined in aqueous solutions with pH 3-9. Mica dissolution was demonstrated to involve ion exchange and adsorption and depend on the acid-basic properties of surface oxides. The rate of mica dissolution is limited by the rate of silicon leaching in acid solutions and by the rate of aluminum leaching in alkaline solutions
