Sintered Ore Philippine Sinter Corporation

Sintering of iron ore is a pre-process vital to steel manufacturing. It begins with the mixing of fine iron ore, solid fuel such as coke breeze & anthracite coal, and flux such as limestone & dolomite. Sintered Iron Ore/ Sintered Ore (SO) is the result of the sintering process. The product is made of ferrous and calcium which can be produced

Limestone Its Processing and Application in Iron and

Jul 07, 2017· Application of limestone and lime in iron and steel plant. During the production of iron by blast furnace (BF) route, limestone is added either in the process of sintering or as a direct feed in the blast furnace. Limestone is normally added during ironmaking for obtaining either neutral or

What Is Iron Ore Sintering? (with pictures)

Dec 06, 2020· Specifically, iron ore sintering requires the use of fine ore, produced by crushing high-grade iron ore into particles only a few millimeters in diameter. Depending on the specific machine and iron ore sintering process used, substances such as coke breeze and burnt limestone are used to ignite and heat the iron ore particles until the

Lead smelting Wikipedia

Plants for the production of lead are generally referred to as lead smelters.Primary lead production begins with sintering.Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal.

Sinter plant Wikipedia

Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux (limestone) fines. In addition to base mix, coke fines, flux fines, sinter fines, iron dust (collected from plant de-dusting system & ESP) and plant waste are mixed in proportion (by weight) in a rotary drum, often called mixing and nodulizing drum. Calcined lime is used as binder of the mixed material along with water (all in particular proportion by weight) to form feed-sinter of about 5 to 7 mm in size. This sinter globules are f

Ore Sinter an overview ScienceDirect Topics

For example, in blast furnace iron making, Fig. 5.1, iron oxide in the form of lumpy ore, sinter or pellet along with coke and limestone, are charged on the top of the furnace continuously. The charge slowly moves down and hot reducing gases produced by burning of coke in front of tuyeres move up through the bed of solids and finally escape
