WO1996001333A1 Sintering an iron ore blend containing

A process for sintering an iron ore blend of iron ore particles, the iron ore blend comprises soft/porous ores is disclosed. The process comprises forming a green mix of the iron ore blend and a flux; granulating the green mix with water; and sintering the granulated green mix. The process is characterised by a treatment step to inhibit absorption of water into the soft/porous ores.

fluctuation of delivered material is decreased. The entire process is called the blending operation in iron ore handling. Bed blending theory was firstly discussed by Gerstel in 1977 (Gerstel, 1977). Not far from that, Gy presented a new bed blending theory to suppress the continuous input variations for a steady output quality grade (Gy, 1981).

How Metals are Made

How Metals are Made

Nov 13, 2017 The most common ore used for aluminum production is bauxite, a claylike substance that is around 50 percent alumina—aluminum bonded with oxygen. As with iron, getting to the aluminum means getting rid of the oxygen and the minerals in the ore. The process is much more complicated than iron extraction, and was only developed in the late 1800s.
