International space agencies are aiming to establish permanent outposts on the lunar surface. For that purpose, new technologies and equipment being developed which will enable augment these mission goals. To increase duration of a long-term planetary expand capabilities, ability manufacture transparent glass in-situ could be an important enabler Results presented in this work show it is feasib...

The effect of differential crushing on liberation characteristics has been studied for a low volatile coking coal Indian origin through washability studies. Two parameters, namely “Index Washability” (IW) and “Near Gravity Material Index” (NGMI), are used to describe the ease washability. ROM Coal is crushed four different top sizes namely, 75mm, 25mm, 13mm 6mm.On basis calculated IW it observe...

Fly ash generated from low NOx burners at American Electric Power's Glen Lyn facility was beneficiated to remove residual carbon, magnetic particles, and cenospheres. The clean fly ash had a mean particle size of about 30 microns, which is coarser than typical commercial fillers used in plastics. To obtain a finer sized fly ash, air classification was used to separate the clean fly ash into its...

This paper introduces the concept of Pigou-Dalton transfers between populations of income receivers. Gini’s mean difference and Dagum’s Gini index between populations are axiomatically derived in order to gauge the impact of withinand between-group PigouDalton transfers on Dagum’s measure. We show its sensitiveness for any given transfer in the sense that inequality-reducing transfers are captu...

<p>The purpose of this research was to evaluate the effectiveness low-cost adsorbents for removal MTBE by employing natural kaolin clay with surface modification KOH. The feasibility examination High Pressure Liquid Chromatography (HPLC) in aqueous solution investigated. To get rid impurities, goes through a beneficiated process. Then, thermal procedure carried out at 990°C prepare adsorb...

Abstract Kaolin (china clay) is a rock material that very rich in kaolinite. A kaolin ore from Debre Tabor, Ethiopia containing 59.2 wt% SiO 2 , 24.9 Al O 3 2.4 Fe 3, and 8.22 loss on ignition (LOI) was physically beneficiated, chemically leached, thermally treated for possible industrial use, especially ceramic membrane fabrication. The leaching experiments were carried out using oxalic acid s...

Abstract In a way to overcome challenges with global warming, the use of fossil fuels in producing environmentally friendly energy towards reducing ozone layer depletion and greenhouse gas emissions by participating countries is interest. The adsorption refrigeration system has advantages long lifespan its environmental friendliness; however, major disadvantage low coefficient performance, whic...

The present environmentally-friendly coal processing technology discussed herewith focuses on the combined effect of ultrasonic and microwave energy in extent mineral matter (ash yield) removal from high-sulfur, low-quality coals for their clean utilization. novelty this study is that technique very efficient instead using drastic chemicals with less treatment time, amount reagent comparison to...

The mining industry is faced with the problem of depletion reserves easily beneficiated minerals containing valuable metals. characteristic features ores involved in processing are fine dissemination; low content components; and similar physical, chemical, surface, technological properties minerals, among others. Under such conditions, increasing efficiency mineral becomes primary importance. C...
