What is an ore sorter?

An ore sorter is an important facet of the mining industry. Typically, high-performance ore sorters work by scanning passing material via a belt or chute feeding system and identifying mineral properties with a scanner. Material that passes one or more selection criteria is identified and separated into chambers via a precise burst of air.

The new sensor-based ore particle sorting offers a powerful method for pre-concentration or waste rejection early in the comminution (the crushing and grinding of the ore to reduce it to finer particles) process. The technology analyses each rock particle on-line for unique physical and chemical properties and separates the particles by high jet pressure air jets.

The technology has the ability to reduce impurities by up to 84% and improve Calcium grade by up to 30%.
