RECOVERY OF IRON FROM LOW-GRADE HEMATITE ORE USING COAL-BASED DIRECT REDUCTION FOLLOWED BY MAGNETIC SEPARATION
In the present work, iron recovery from a low-grade hematite ore (containing less than 40% iron), which is not applicable in common methods of ironmaking, was studied. Non-coking coal was used as reducing agent. Reduction experiments were performed under various coal to hematite ratios and temperatures. Reduction degree was calculated using the gravimetric method. Reduced samples were subjected...
متن کاملMagnetic Separation of Giardia Cysts from Water
Background: Giardia is one of the infectious agents that can be transmitted by surface water and cause a disease. We designed and fabricated a magnetic system to separate the giardia cysts from water. Materials and Methods: In this study, giardia cysts were concentrated by sucrose floatation method. The cysts were mixed with physiological saline and their concentration was adjusted to 100,000 c...

15 صفحه اولCarbon elimination from silicon kerf: Thermogravimetric analysis and mechanistic considerations
40% of ultrapure silicon is lost as kerf during slicing to produce wafers. Kerf is currently not being recycled due to engineering challenges and costs associated with removing its abundant impurities. Carbon left behind from the lubricant remains as one of the most difficult contaminants to remove in kerf without significant silicon oxidation. The present work enables to better understand the ...
متن کاملA Review of Technology of Metal Recovery from Electronic Waste
Electronic waste, or e-waste, is an emerging problem with developed nations as with developing nations. In the absence of proper collection and disposal systems, aware‐ ness, and proper regulations, the problem is rather more acute in developing nations. These wastes are environmentally hazardous on one hand and valuable on the other. They contain substantial amount of metal value, including pr...
