High capacity separation of coarse ore minerals from waste minerals
First Claim
1. A system configured for sorting unclassified coarse mineral material, the system comprising:
- a first material transport system configured to transport unclassified coarse mineral material in a first direction;
a second material transport system configured to transport unclassified coarse mineral material to the first material transport system, wherein;
the speed of the first material transport system is approximately the same as the speed of the second material transport system such that the second material transport system deposits unclassified coarse mineral material on the first material transport system in a heaped or touching arrangement;
a first array of first sensors aligned approximately transverse to the first direction,wherein;
the first sensors generate first data signals;
a second array of second sensors positioned downstream of the first array of first sensors in the first direction and aligned approximately transverse to the first direction, wherein;
the number of second sensors in the second array is equal to the number of first sensors in the first array; and
the second sensors generate second data signals different from the first data signals;
an array of diverters positioned at a terminal end of the first material transport system, wherein;
the number of diverters is equal to the number of second sensors in the second array; and
each diverter is aligned with a first sensor in the first array and a second sensor in the second array in a direction generally parallel to the first direction to thereby divide the first material transport system into a plurality of sorting channels; and
a signal processing system configured to receive and process the first and second data signals from the first sensors in the first array and the second sensors in the second array, respectively, and direct each of the diverters to a reject or accept position based on the signals received and processed, wherein;
the signal processing system receives and processes signals and directs diverters to accept or reject in less than 2 ms.

Abstract
Systems and methods for delivering mining material to a multimodal array of different types of sensors and classifying and sorting the mining material based on the data collected from the multimodal array of sensors. The arrays of different sensors sense the mining material and collect data which is subsequently used together to identify the composition of the material and make a determination as to whether to accept or reject the material as it passes off the terminal end of the material handling system. Diverters are positioned at the terminal end of the material handling system and are positioned in either an accept or reject position based on the data collected and processed to identify the composition of the mining material.
