Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.

Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.

About Us. We - Prakash Agro Mills are a renowned name in the manufacture, export and supply of wide range of food grains and products. We are determined in our promise to supply the finest quality in every respect in our food products like iron ore fines, pure ferric chloride, iron ore lumps, laboratory ferric chloride.

Abstract. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described to identify the key steps of the process, that is, granulation and thermal densification. Discussion is then focused on the effect of the chemical, physical ...

The main impurities in the manganese ore and mill scale are CaO, MgO, Al 2 O 3, and SiO 2. Before roasting, all the raw materials were crushed, ground, and screened to 100 wt% by being passed through a 0.074-mm mesh in advance. The average particle sizes of the mill scale and manganese ore powders are 29.4 μm and 24.2 μm, respectively.

Introduction. India is rich in iron ore deposits and is the fourth largest useable iron ore producer globally as of 2019–20. As per the Steel Policy 2017–18, around 450 MTPA (million tons per annum) of high-grade iron ore resources are required to meet the steel demand of 300 MTPA in 2030, shown in Fig. 1.

The roasted ore fines were mixed in sinter blend between 2 and 5% to maintain Fe: ∼55% and Mn: ∼0.3 to produce high Mn pig iron. It was seen that the material performed well in the sintering process, however, due to lower blend proportion measurement of its impact on the coke rate was not feasible to establish.

During sintering, fine iron ore particles are mixed with a small amount of coal (5% by weight), and the mixture is then ignited (Peters, 1982).The process is driven by the decrease in surface energy (surface area) that causes the edge of the particles to fuse together (Fig. 1).The particles produced in this manner have a lower density than …
