Better operating results are obtainable when the ore burden for LG-6 ore consist of 50% lumps and chips; 30% concentrate, 20% pellets. For large furnaces, efficient smelting is not always achievable with a raw material burden containing 50% of the ore as concentrate fines, while all UG-2 ore needs to be pelletised.

Learn about the steps involved in iron ore processing, from crushing and grinding to separation. Contact Multotec experts for guidance on iron processing.
Ever heard the the terms "face" and "back"? Well, it turns out that they have been around since the early days of mining. The roof of the tunnel was called the "back" because miners had their backs to it while shovelling ore. The "face" was the end of the tunnel that they were retrieving ore from, which was what they faced while at work. Makes ...
8.1. Introduction. Hematite and magnetite iron ores are the most prominent raw materials for iron and steel production. 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).
The ROM retaining wall utilises a Reinforced Earth (RE) design solution. This design approach has the benefit of requiring only simple and small concrete strip foundations. In addition, the RE wall has the flexibility to accommodate foundation settlement and any resulting movement in the wall and working platform.
Mathematical modeling in conjunction with mineral characterization is widely used as a method for design and optimization of comminution circuits, to simulate the processes of crushing, grinding and classification. An important input parameter to the simulation models is the Run-of-Mine Particle Size Distribution (ROM PSD).

The customer achieved a cleaner ROM pad for road trains to drive on safely, without tyre damage. Wearpact was found to be easier and safer to install and remove.
Iron Ore, in its raw form, may not be the most appealing to the eyes, but it holds immense potential. It is a primary ingredient in the creation of steel, a material fundamental to our modern world. Iron Ore doesn't apologize for its rough exterior, instead, it embraces its natural form, knowing the strength and value it holds within.
