The mould making essentially consists of preparing a cavity having the same shape as the part to be cast by means of ‘pattern’. Green sand refers to an intimate mixture of sand, bentonite clay and water. In green sand moulding process, clay along with water is used as binder. Normally a pair of flasks is used for preparation of mould.
Copper is so valuable that its theft from worksites and power substations has become anational problem. Replacing the lost copper with new metal produced by the traditional method of cooking copper sulfide ores requires a multistep process to extract the copper and produces troublesome byproducts.Antoine Allanore, the Thomas B. King Assistant Professor of Metallurgy at MIT, wants to simplify copper extraction and eliminate noxious byproducts through electrolysis.

are cinnabar HgS, an ore of mercury, sphalerite ZnS, an ore of zinc, or cassiterite SnO 2, an ore of tin Mineral. Part A The table lists several ores of metals and their chemical formulas. Identify the metal that each mineral ore is a source of by looking at the formula. You can use your ESRT to find the symbol for each element.
Iron39s use by humans dates back about 5,000 years. It is the second most abundant metal element in the Earth39s crust and is primarily used to produce steel, one of the most important structural materials in the world.
Iron element 26, symbol Fe is the most common metallic element in the universe.nbsp When pure it is a dark, silvery-gray metal. It is a very reactive element and oxidizes rusts very easily. The reds, oranges and yellows seen in some soils and on rocks are probably iron oxides. Iron is the third most common element making up the Earth.nbsp Iron is one of the three naturally magnetic elements the others are cobalt and nickel. Iron is the most magnetic of the three.
The principle ores of iron are hematite 70 iron and magnetite 72 iron. Taconite is a low-grade iron ore, containing up to 30 magnetite and hematite.
Question What is the chemical formula for iron ore Ores Ores are rocks that contain enough of a mineral for the extraction of that mineral to be economically viable.

It is estimated that worldwide there are 800 billion tons of iron ore resources, containing more than 230 billion tons of iron. It is estimated that the United States has 110 billion tons of iron ore representing 27 billion tons of iron. Among the largest iron ore producing nations are Russia, Brazil, China, Australia, India and the USA. In the United States, large deposits are found in the Lake Superior region. Worldwide, 50 countries produce iron ore, but 96 of this ore is produced by only 15 of those countries.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. Raw iron is alloyed with a variety of elements such as tungsten, manganese, nickel, vanadium, chromium to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks, trains and train tracks.
In the United States, almost all of the iron ore that is mined is used for making steel. The same is true throughout the world. Raw iron by itself is not as strong and hard as needed for construction and other purposes. So, the raw iron is alloyed with a variety of elements such as tungsten, manganese, nickel, vanadium, chromium to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks, trains and train tracks.
