heat is used to raise the temperature of an ore because most chemical reactions happen faster at high temperatures this process helps change the chemical state of the iron metal atoms which forces them to break their bonds with non-iron atoms.get price



How steel is madea summary of a Blast Furnace

Iron ore and other iron bearing materials coke and limestone are charged into the furnace from the top and work their way down becoming hotter as they sink in the body of the furnace which is called the stack. In the top half of the furnace gas from burning coke removes a great deal of oxygen from the iron ore.get price



Copper Production How Is Copper Made

Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0 copper.get price



How Metals are Made

Iron ore is smelted in a blast furnace Superheated air—up to 2 200°F—is "blasted" into the furnace causing it to burn much hotter than it otherwise could. A typical blast furnace at a steel mill runs for 24 hours a day 365 days a weeks for up to 20 years before it must be replaced. Pure steel is very susceptible to rust.get price

How do we extract minerals USGS

The rock is drilled and blasted then moved to the surface by truck belt conveyor or elevator. Once at the surface the material is sent to a mill to separate the ore from the waste rock. Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods which generally cost less than underground methods.get price



Iron and steel industry in the United StatesWikipedia

The coke reduces the iron oxide in the ore to metallic iron and the molten mass separates into slag and iron. Some of the iron from the blast furnace is cooled and marketed as pig iron the rest flows into basic oxygen furnaces where it is converted into steel.get price

Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel or by grinding the ore in a ball rod or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury.get price



Ball Millan overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.get price
