Beneficiation of lunar ilmenite

open access: yes, 1991
One of the most important commodities lacking in the moon is free oxygen which is required for life and used extensively for propellent. Free oxygen, however, can be obtained by liberating it from the oxides and silicates that form the lunar rocks and ...

Reaction‐Driven Development of Fine‐Grained Plagioclase Networks Influences the Rheology of the Crust in the Bergen Arcs, Norway

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 6, Page 470-491, July 2026.
ABSTRACT In the middle to lower continental crust, mineral reactions can play a key role in controlling rheological behaviour by generating fine‐grained, mechanically weak domains. In granulite‐facies rocks from Krossøy (Bergen Arcs, Norway), we document how garnet breakdown produced interconnected networks of orthopyroxene + plagioclase ± spinel that ...

Low Abundances of Ultramafic Components in the Chang'e‐6 Landing Site Basalt and Ejecta Material

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The South Pole‐Aitken (SPA) Basin, the Moon's largest impact structure, holds key insights into lunar evolution, prompting the Chang'e‐6 mission to return first samples for ground‐truth verification. Analysis of over 6,000 grains from the Chang'e‐6 soil returned from the SPA Basin reveals a composition dominated by clinopyroxene (26.5–32.9 vol.

Carbothermal reduction and nitridation of ilmenite concentrates

open access: yes, 2012
Carbothermal reduction and nitridation of ilmenite concentrates of different grades and synthetic rutile were studied in isothermal experiments in hydrogen – nitrogen gas atmosphere and pure nitrogen in a tube reactor. Concentrations of CO and CO2 in the

Mechanically activated carbothermic reduction of ilmenite

open access: yes, 1997
A systematic study of the effect of milling conditions on the low-temperature carbothermic reduction of the mineral ilmenite has been carried out. It was found that after ball milling of an ilmenite-carbon mixture at room temperature, the ilmenite was ...
