Five stages of gypsum production process Stone

15-01-2012  Gypsum production process. Gypsum ore, from quarries and underground mines, is crushed and stockpiled near a plant. Asneeded, the stockpiled ore is further crushed and screened to about 50 millimeters (2 inches) in diameter. If the moisture content of the mined ore is greater than about 0.5 weight percent, the ore must be dried in a rotary dryer or a heated roller mill. Ore dried in a rotary

Direct Iron Ore Smelting Process for Ironmaking –

Direct iron ore smelting (DIOS) process is a smelting reduction process for the production of hot metal (liquid iron). It is a two-stage process which has been developed in Japan. It uses non-coking coal in a powder or granular form to smelt iron ore fines into liquid iron (hot metal) and hence, there is no necessity of a coke ovens plant and a sintering plant.

Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore

Creating Iron HowStuffWorks

At this point, the liquid iron typically flows through a channel and into a bed of sand. Once it cools, this metal is known as pig iron. To create a ton of pig iron, you start with 2 tons (1.8 metric tons) of ore, 1 ton of coke (0.9 metric tons) and a half ton (0.45 metric tons) of limestone. The fire consumes 5 tons (4.5 metric tons) of air.

18-01-2014  Fine iron ore is preheated and reduced to fine direct reduced iron (DRI) in a three or four stage fluidized bed reactor system. The fine DRI will be compacted and then charged in the form of hot compacted iron (HCI) into the melter gasifier. The charged HCI is subsequently reduced to metallic iron and melted. The generated FINEX export gas is a highly valuable product and can be further used.

Description: Iron ore fines come from the natural raw iron ore through the process of mining, crushing and screening, where the iron ore is separated into lumps and fines. Iron ore is done in this fashion so that it can be used for the iron/steel making industry. When the iron content in the processed iron ore contains more than 60%, which would generally be the lumps, they are shipped directly to the plants.
