Sinter overlying the first quartz andesite flow at base of Serra Geral Group is a surface manifestation intense hydrothermal processes operating in Paraná Basin during Early Cretaceous. The coarse sinter from western Rio Grande do Sul state was studied satellite images, field surveying, optical petrography, scanning electron microscopy, and probe microanalyses, including backscattered images ch...

The metallurgical properties of blast-furnace ore and ore-coal extrusion briquettes (BREX) based on hematite iron concentrate are studied. With respect to values hot strength brex occupy an intermediate position between sinter pellets. reduction capacity for is significantly reduced with simultaneous addition flux solid fuel, which may be associated a in porosity (due clogging pores the formati...

Mill scale is one of the byproducts which produced during processing steel. It rich in iron (≥70%), has lower impurities and a stable chemical composition. The present research studies effects partial replacement ore with different proportions mill on sinter charge. results this study showed that an increase substitution by at 3%, rate production increases from 21.94 to 25.50 ton/m2/day (16.2%)...

1.0 INTRODUCTION Active and fossil hot springs systems occur worldwide, and share many common characteristics that indicate similar genetic histories (White 1955; Waring 1965; Rhinehart 1980; White 1981; Bowen 1989). This research studies the occurrence and characteristics of hot springs at Steamboat Springs, Nevada using Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data. Both highan...
