Use of a mixture of coal and oil as an additive for selective reduction of lateritic ore by the Caron process [PDF]

Hemijska Industrija
Lateritic ores constitute the main source of raw material for extraction of Ni and Co by the Caron process. Consumption of oil in the reduction furnace is one of the key indicators if the metallurgical process is economical.

Assessment of the possibility of using leucoxene-quartz concentrate as raw material for production of aluminium and magnesium titanates

Записки Горного института, 2023
Leucoxene-quartz concentrate is a large-tonnage by-product of development of the Timan oil-titanium field (oil-saturated sandstones) which is not commercially used at present. High content of titanium compounds (to 50 % by weight) and lack of industrial,

Comparative Insights Into the Accuracy of Quantitative Phase Analysis of Lithium‐Ion Battery Recycling Slags

Advanced Energy and Sustainability Research, Volume 7, Issue 10, October 2026.
Pyrometallurgical slags from lithium‐ion battery recycling are thermochemically conditioned to form lithium‐bearing “engineered artificial minerals” that enhance lithium recovery. Following chemical characterization (wavelength‐dispersive X‐ray fluorescence spectroscopy, inductively coupled plasma optical emission spectroscopy, electron probe ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Safety soft sensor development for pilot‐scale ilmenite electric arc furnace using long short‐term memory‐based architecture

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4702-4718, September 2026.
Abstract Ilmenite electric arc furnaces (EAFs) are used for smelting titanium‐iron oxide ore at high temperatures generated by electrical arcs to produce titanium slag and pig iron. As these units are pushed to their limits, ensuring safe and reliable operation becomes challenging.
