Three STEINERT KSS sorting systems extend the life of mine in Mexico. In 2018 an industrial mineral mine in central Mexico installed its first Steinert ore sorter to improve the run of mine grade, which had gradually been decreasing with the aging of the mine. This first successful installation was followed by two more Steinert multi-sensor ...
