Surface modification and column flotation of a massive Ilmenite ore

open access: yes, 2002
The main problems with ilmenite flotation in impeller-type flotation machines are the poor flotation behaviour of ilmenite and the negative effect of slimes. These cause high ilmenite losses in tailings even when a large dosage of fatty acid and fuel oil

Industrial-scale trials for the production of oxidized Panzhihua ilmenite concentrate pellets followed by smelting in an EAF for titania slag production

open access: yesResults in Engineering
Electric arc furnace (EAF) smelting of ilmenite concentrate is the primary method for upgrading titania, producing high-quality titania slag for titanium dioxide and sponge titanium production, while also enabling the recovery of hot metal for ...

Experimental Study on the Flotation Desulfurization of Vanadium Titanium Magnetite Concentrate in Panxi

open access: yesKuangchan zonghe liyong, 2022
Grades of Fe, TiO2 and S in the vanadium titanium magnetite concentrate in Panxi are 53.75%, 12.55% and 0.76%. Fe and Ti are mainly in the form of vanadium-titanium magnetite and ilmenite, while sulfur is mainly in the form of magnetic pyrite.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Spectral‐Kinetic Synergy in Au‐Network Engineered FeTiO3: A Multi‐Field Coupling Strategy for Lunar In Situ Resource Utilization

open access: yesAdvanced Science, EarlyView.
How can humanity achieve lunar self‐sufficiency? We utilize Au topology networks to modify the abundant lunar ilmenite. This catalyst, under sunlight, can convert waste carbon dioxide into space fuel. This design leverages the moon's natural vacuum for green manufacturing, avoiding the waste of gold and serving as “artificial chloroplasts” to sustain ...

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

open access: yesGeological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

open access: yesGeological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Prospects of Eliminating Fluorspar Consumption in a Sustainable Argon‐Oxygen‐Decarburization Process

open access: yessteel research international, EarlyView.
This study aims at identifying pathways for eliminating fluorspar consumption in the argon‐oxygen‐decarburization (AOD) process. Thermodynamic calculations suggest the feasibility of completely replacing fluorspar with alternative fluxes such as Al2O3, Na2O, K2O, and Li2O of suitable amounts.

An Uncommon Instance of Egyptian Blue in the “Pigmented Intonachino” of the Fishpond Wall Painting From the Roman Villa of Torre di Pordenone (Northeast Italy)

open access: yesArchaeometry, EarlyView.
ABSTRACT The increasingly close integration of analytical techniques in the study of Greek and Roman wall paintings has shown that Egyptian blue was a common pigment, widely documented in the production of blue and greenish hues in ancient painted production.
