The island of Milos is an active mining site since the Antiquity. Exploitation began with extraction obsidian lumps and volcanic lavas tuffs specific type, that were used as millstones, sulphur alum (alunite). Currently, activity focused on perlite bentonite, even though some years ago, kaolin, silica, pozzolans barite also exploited. bentonite rather a specialty not commodity, it has multifunc...

This work describes a systematic method for the analysis of attrition and residual morphology natural fibers during compounding process by twin-screw extrusion. There are several methods assessment fiber lengths morphology, although they usually based on use non-affordable apparatus or time-consuming methods. In this research, variation morphological features such as length, diameter aspect rat...

A number of persistent problems have been associated with the supply traditional domestic fuels in developing countries and particularly rural areas, including deforestation, scarcity fuel wood high cost fossil fuels. The use biomass derived from agricultural waste biomass, generally available large quantities, has advocated. This article, therefore, presents some bio-fuels or acceptability tes...

Mixed Ta 2 O 5 – TiO binary system was studied by a combination of differential thermal analysis (DTA), scanning electron microscopy-energy dispersive spectrometry (SEM-EDS), X-ray diffraction (XRD) and in situ high temperature (HT-XRD) techniques. Different compositions the mixed oxide powders were fabricated ball–milling powdered compositions, pelletizing homogenized composite powders, heatin...

Biomass plays a crucial role in mitigating the concerns associated with increasing fossil fuel combustion. Among various types of biomass, forest biomass has attracted considerable attention given its abundance and variations. In this work, an overview is presented on different pathways available to convert into bioenergy. Direct use could reduce carbon dioxide emissions conventional energy pro...

Vanadium titanomagnetite is an important mineral resource. It a raw material for ironmaking, vanadium extraction, strategic metal titanium production, and dioxide production. In this study, high chromium (High-Cr VTM) ordinary iron ore were used as materials pelletizing. The effect of V2O5 on the preparation properties High-Cr VTM pellets was studied. influence green pellets, compressive streng...
