3. Mineralogy of Iron Ore 3 Iron ore is regarded as naturally occurring mineral that is used for extraction of metallic iron under existing economical and technological conditions. Iron, an abundant element, occurs in variable amounts in many minerals. However few of them contain appreciable amount of iron, from which iron can be economically obtained. Iron forms …
Concentration Finely crushed ore concentrated by the froth-flotation process: • Ground ore mixed with xanthates (salts & esters of xanthic acid), dithiophosphates, or thionocarbamates. These make the ore surface hydrophobic. • Ore then introduced into a water bath where air is bubbled through the suspension.
Which involves the process of collecting lots or portions of productive rocks or ores. The main purpose is to determine the quality (or) composition of a material. ...

4. Some Terms – Lets Have a Look Minerals: A solid element or compound which occurs naturally in the Earth's crust is called a mineral. Ore: A mineral from which metals can be extracted profitably is called a metal ore. Profitable extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal.
11. Magnetic drum separators are important magnetic separators that removes ferrous metal from dry bulk products in free-flowing processing systems. They are self cleaning unit consisting of drums and housing normally of stainless steel. The magnets used by the magnetic drum separators are either ceramic magnets or rare earth magnets.
4. What is an Ore? Ore: Rock materials that exist in quantities that can be extracted and profitably mined for a mineral (often a metal) or for minerals (metals). An ore is a mass of mineralization within the Earth's surface which can be mined: at a particular place; at a particular time; at a profit Marketed for a profit. Ore: refers to useful metallic minerals that can be mined …

3. Leaching is widely used in the biological and food processing industries, such as the separation of sugar from sugar beets with hot water. The extraction of oils from peanuts, soybeans, sunflower seeds, cotton seeds, and halibut livers. In pharmaceutical industry, many products are obtained by leaching plant roots, leaves, and stems. In the metals processing …
The process- A current of air is sent with miniumum turbulence through a series of tubes. The tubes have increasing diameters. A 50 gm sample ore is introduced into the air stream. The infra-sizer and the sample should be dry. Electrostatic effects on the particles is reduced / removed by using conducting rubber in the flexible connections. 175
4. • Process metallurgy, The science and technology used in the production of metals, employs some of the same unit operations and unit processes as chemical engineering. These operations and processes are carried out with ores, concentrates, scrap metals, fuels, fluxes, slags, solvents, and electrolytes. Different metals require different combinations of …
