Cesium (Cs) is a waxy, silvery-gold metallic element that is the softest of all metals. Cesium is one of three metals (gallium and mercury) that are liquid at or near room temperature. Cesium is a very reactive metal, that when mixed with cold water, produces an explosive reaction. Its melting point is so low that it will melt if it is held in ...

m/s. Ore sorting benefits from the natural heterogeneity of deposits, and should be implemented as early in the process as possible where the variability is greatest and to maximise the benefits.

As can be seen, after the second sorting, the Grade 2A pieces had 3.07 wt % Cs 2 O, evidence that the first sorting did a very efficient job of recovering the cesium from the secondary ore, and the second sort yielded additional cesium missed by the first sorting. Table 1 further shows the "Step 2 Accepts", the Grade 2B pieces.

What is ore sorting? Ore sorting involves identifying and removing waste and below-grade ore to preconcentrate the process plant feed. It produces higher, more stable head feed grades that essentially 'preserve' the processing capacity for economic ore – ore that holds higher value than the cost of processing. Ore sorting can reduce ...

Keywords: ore sorting; ore characterisation; sortability 1. Introduction Sensor-based ore sorting is a pre-concentration technique that uses electronic sensors to differentiate ore particles based on measurable physical properties that are intrinsic to the ore, i.e., naturally occurring properties (grade, texture, mineralogy, density, colour etc.).
