Separation by flotation is one of the common technologies used during beneficiation stage in mining industry, aiming at concentrating valuable minerals for downstream refining stages. Currently a new froth technology being developed under FineFuture (FF) project, funded European Union Horizon 2020 research and innovation programme (grant agreement No 821265). If implemented, this can valorise f...

Introduction: CRISM hyperspectral images of Mars have recently been used to identify what are interpreted as magnesium carbonate deposits composed of magnesite mixed with one or more hydrated phases [1]. Using existing approaches to parameterize spectral data from CRISM [2], thousands of high-resolution targeted observations have been examined for occurrences of this material. Results to date i...

The Mg0-Mn203-Mn0 system in air exhibits two series of solid solutions, (Mg,Mn)Mn204 and (Mg,Mn)O, the boundaries of which have been located. At 1600 +5' C a tie-triangle exists in which these two solid solution phases and a liquid phase coexist with the gas phase. The Mn3+/Mn2+ ratio of the crystalline phases is lowered by the addition of CaSi03 and this has the effect of stabilising the (Mg,M...

Introduction: The recent discovery of carbonaterich outcrops in the Nili Fossae region of Mars using data returned by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument [1] as well as indications of 2-3% carbonate in alkaline soils at the Phoenix landing site [2] have brought into question the hypothesis that much of martian history has been dominated by an acidic weath...
