coke and limestone and reducing it to metal. Blasts of hot air enter the furnace from the bottom and provide the oxygen which is necessary for the reduction of the ore. The ore becomes molten, and its oxides combine with carbon from the coke. The nonmetallic constituents of the ore combine with limestone to form a liquid slag.
Marl is a limestone with admixtures of silex and clay substances, as well as iron oxide.It is a transitional stage to clay. The hardness of marl is lower than the hardness of limestone The more clay substances, the lower its hardness. This is an excellent raw material for cement production. Each of these materials has different grinding

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high
Abstract. We report a type of high-magnesium and low-silicon iron ore tailings (IOT) utilized as a raw material replacing clay to produce cement clinkers by conventional sintering process. Properties of the cement clinkers sintered at 1420 °C with different IOT addition, from 0 to 20 wt%, were investigated.

The crushing process is the two-stage open circuit crushing and comprises the following steps that: raw ores are subjected to first-stage crushing in a first-stage screening-crushing machine, the crushed materials are subjected to first-stage screening, the oversize materials obtained by the
The goal of producing and processing limestone ore (mostly CaCO3 ) is to obtain high-quality refractory materials based on lime (CaO). . This paper explores the preparation of lime by roasting the limestone deposits of Strezovci (Republic of Kosovo) and its use for obtaining calcium through the aluminothermic process
Cement clinker is manufactured by heating the blended and ground raw material (typically limestone and clay or shale and other materials) to partial fusion. The clinker burning takes place at a temperature of 1450°C in kilns, which are normally inclined rotating cylinders lined with heat-resistant bricks.
Marl is a limestone with admixtures of silex and clay substances, as well as iron oxide.It is a transitional stage to clay. The hardness of marl is lower than the hardness of limestone The more clay substances, the lower its hardness. This is an excellent raw material for cement production. Each of these materials has different grinding
Cement is a binding that sets, hardens, and adheres to other material to bind them together. It is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Limestone, shells and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand and iron ore are used

Some of its applications include sculptors, floor tiles, window sills, stair treads, and others. The famous pyramid of Giza in Egypt is made out of limestone. Additionally, limestones containing clay content are utilized in the production of cement. Limestone aggregate is also used in road and railroad construction.
Limestone is also a very important industrial mineral. Its chemical properties make it a valuable mineral for a wide range of industrial/manufacturing uses. Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight.
