In this work, we discussed the possibility of using deep learning through an edge AI platform to classify iron ore during its transportation in conveyor belts. This technique uses a compressed DNN model running in an edge computing device to enable the deployment of an intelligent sensor directly in the working area.

The recovery and concentration of ultra-fine iron ore can provide significant economic benefits. Presently, there are limited options available given the low settling rates achieved by conventional gravity separation and the relatively poor performance of reverse flotation. The Reflux Classifier is a new water-based gravity separation technology that consists …

In order to accurately estimate iron ore grades and reserves, the geology and geochemistry of the subsurface must be mapped accurately. In resource evaluation at Rio Tinto Iron Ore, block models are created through drilling and interpreting RC holes (Sommerville et al., 2014). RC chips from these holes are logged and assayed in 2 m intervals.

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.

Description. The REFLUX™ Classifier is a recently developed water-based gravity separation technology that is already being used worldwide to beneficiate particles above 0.100 mm in size. This paper reports tests performed on an ultra-fine iron ore with nominal top size of 0.106 mm, but with 59 wt-% being below 0.038 mm in size.
