Hydrometallurgical refining of metallurgical silicon
The paper presents the results of refining silicon of metallurgical grades based on leaching of impurities with inorganic acids. Silicon samples were studied by metallographic and X-ray fluorescent methods of analysis, as well as X-ray spectral ...

Advances in Understanding of the Application of Unit Operations in Metallurgy of Rare Earth Elements
Unit operations (UO) are mostly used in non-ferrous extractive metallurgy (NFEM) and usually separated into three categories: (1) hydrometallurgy (leaching under atmospheric and high pressure conditions, mixing of solution with gas and mechanical parts ...

PHASE FORMATION DURING STEEL REFINING BY ALLOYS WITH ALKALINE EARTH ELEMENTS (Ba, Mg, Sr)
Important factors affecting the quality of steel are both the level of metal contamination with non-metallic inclusions and the properties of these inclusions.

Grain Refinement of Ti-15Mo-3Al-2.7Nb-0.2Si Alloy with the Rotation of TiB Whiskers by Powder Metallurgy and Canned Hot Extrusion [PDF]
In situ synthesized TiB whiskers (TiBw) reinforced Ti-15Mo-3Al-2.7Nb-0.2Si alloys were successfully manufactured by pre-sintering and canned hot extrusion via adding TiB2 powders. During pre-sintering, most TiB2 were reacted with Ti atoms to produce TiB. During extrusion, the continuous dynamic recrystallization (CDRX) of β grains was promoted with the

Archaeology, science-based archaeology and the Mediterranean Bronze Age metals trade [PDF]
Archaeologists often seem either sceptical of science-based archaeology or baffled by its results. The underpinnings of science-based archaeology may conflict with social or behavioural factors unsuited to quantification and grouping procedures.

Factors influencing power consumption and power-saving measures in ESR process [PDF]
Since the USA patent of electroslag remelting (ESR) metallurgy was held by P. K. Hopkins in 1940, the ESR technology has now entered a relatively mature stage after a 70-year history of development.
