Viraf J Dalal Chemistry Class 10 Solutions and Answers. Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. 1. I have decided to explain those things which mining people call fluxes because they are added to ores not only for assaying, but also for smelting. Ask your question. (Click here for extraction process). The hot, molten, metallic aluminium obtained in the process sinks to the bottom of the reduction cell, while the gaseous by-products form at the top of the cell. The ore is crushed into a fine powder and a suspension is created in water. The electrical current passes from the carbon anodes via the bath, containing alumina in solution, to the carbon cathode cell lining.

Although the basic ingredients of an iron ore blast furnace has changed little over the last hundred years or so, the furnaces themselves have been modernized to improve efficiency and the purity of the iron and steel. The Hall–Héroult process is the major industrial process for smelting aluminium.It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium's chief ore, through the Bayer process) in molten cryolite, and electrolysing the molten salt bath, typically in a purpose-built cell. Intel® Pentium® Gold processors are optimized for performance, while Intel® Pentium® Silver processors are optimized for cost. Multiple choice questions Question 1(i). ← Prev Question Next Question → 0 votes . Smelting is the process of extracting base metals from ore by heating it to produce the chemical reactions needed to remove the other elements present. This article will walk through how The Crucible produced their own iron through the smelting of iron ore. First, let’s start with understanding the basics. Question 1. Once the extraction process is complete we must ensure that the metal is free of any impurities. Look at the photo belowHere, we see sun above the horizon, but the sun is actually not above the horizon.Infact:We see sunrise 2 minutes before actual sunriseWe see sunset 2 minutes after sunsetThis is because ofatmospheric refractionExplanation for Advanced SunriseBefore Sunrise, sun is … | EduRev Class 10 Question is disucussed on EduRev Study Group by 171 Class 10 Students. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Two PFC compounds are released during anode effects, namely tetrafluoromethane (CF4) and hexafluoroethane (C2F6), which have greenhouse gas warming potential of 6,500 and 9,200 times greater than CO2 respectively. The digestion process is a series of reactions of food with the digestive hormones and juices. Aluminium is often turned into alloy and then used for making various products. Zinc Mining.

Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. explain the breathing process in man. The partially liquefied slags reveal short firing times and relatively low temperatures. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. Fume treatment plants ("FTPs") are used to capture the hydrogen fluoride and recycle it as aluminium fluoride for use in the smelting process. If you remember we have done a similar process before of removing impurities during concentration of ores. To learn more in detail, register with BYJU’S and download our app. Add your answer and earn points. Aluminium fluoride (AlF3) is added to maintain the target bath chemistry. Paddles and air constantly stir up the suspension to create the froth. In addition to carbon dioxide, the aluminium smelting process also emits hydrogen fluoride (“HF”) - an extremely toxic gaseous emission. → The country also export cotton goods to U.S.A., U.K., Russia, France, East European countries, Nepal, Singapore, Sri Lanka, and African countries. Involves electrolysis. Process description: Unlike the Kera oshi, to produce steel with the Zuku method two phases are needed (hence the name "Indirect").
