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.

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand.

If copper recovery depends on (1/d p) and the copper leaching rate depends on (1/d p) 2, leaching of ROM ore in dumps should be impossible, or at least so slow and marginal as to not be profitable.And yet dump leaching of copper secondary sulphides is practiced widely, with good recoveries and at rates rapid enough to be measurable (Yáñez et al., 2007, Bustos et al., …
Abstract: The frequent best practice for managing large low-grade run-of-mine (ROM) stockpiles is to average the entire stockpile to only one grade. Modern ore control and mineral processing procedures need better precision. Low-precision models hinder the ability to create a digital mine-to-mill model and optimize the holistic mining process.

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 ...
