Abstract:
Fayalite crystals from ancient slag found in Volyn region were studied. Fayalite constitutes the bulk of the slag, less common phases of silicon oxide (metallurgical glass), iron (magnetite), unidentified silicate phase X and individual detrital quartz grains. Fayalite crystals have a predominantly skeletal (case-like) shape in the slag matrix and a close combination of several different morphological types of polyhedrons in its cavities. They are faceted by pinacoid {010} and prisms {021}, {110} and {120}. The habit of the crystals is prismatic, pinacoidal and pinacoidal-prismatic, they are o

Abstract The Fayalite syenites of Gokanakonda in Andhra Pradesh, India, are mineralogically divided into two types: (1) fayalite-clinopyroxene syenites (FC-syenites) and (2) fayalite-quartz syenites (FQ-syenites). The olivine composition ranges from Fa90-95 and the petrochemistry suggests their successive evolution in that order. The assemblage (fayalite+magnetite+quartz) in these syenites suggests a pressure of 11.5 kb and a temperature of 900°C under constant fo2.

Background: Being by-products of non-ferrous metallurgy, slags contain fayalite (Fe2SiO4) as the major component. Since hydrometallurgical methods are considered as the most promising for processing such material to obtain valuable metals, increasing the leachability of fayalite in sulfuric acid as a widely used leaching agent is an important task. Objective : The present work was devoted to increasing the reactivity of fayalite by using mechanical activation.

Water-cooled fayalite slag comes in granular form, which is then milled into fine powder (d50 ~10 microns) prior to its alkali activation. In addition, the un-milled granular fayalite slag can be used as an aggregate to replace sand in mortar. The alkaline solution utilized for the study was a m

In this thesis, alkali activation of fayalite slag was investigated. The slag utilized is a waste by product from nickel production, the activation of which resulted in the formation of a geopolymer binder of acceptable properties. The need for a reduction in overall waste output as well as the cementitious properties exhibited by this slag motivated this study. The literature section of this research provides an insight on the previous work in the area of geopolymerization, the source materials used, the activators employed as well as the properties exhibited by various geopolymer products.

Abstract:
Since iron oxide and silicon oxide are major gangue components in various types of ore, FeO-SiO2 base slag, ie fayalite slag, has been often encountered in pyrometallurgical processes of non-ferrous metals. During most matte production processes such as the smelting of Cu, Pb, and Ni, the FeO-SiO2 based slag is inevitably formed and plays an important role in refining crude metal as well as engineering aspects. Recently, similar pyrometallurgical approaches have been attempted in the recovery of valuable metals (Ni, Co, Cr) from wasted secondary batteries. Thus, the viscosity of the FeO-SiO2 b

Abstract:
Abstract The serpentinization of the mafic and ultramafic rocks is one of the most significant mechanisms for producing natural hydrogen in the subsurface. The northern part of Borneo is notable for its complex regional geology, particularly regarding Fe-rich rocks in the ophiolite zone of Sabah. This article discusses the mineralogy of ophiolites in Sabah, which could lead to the natural hydrogen feasibility via serpentinization processes. Fieldworks were conducted in selected outcrops in order to investigate the presence of ophiolites, standard petrography and x-ray diffraction (XRD) analyse
