Grade Control

Grade control is the classification of reserves into ore, low grade, waste material or metallurgical types. X-Ray Fluorescence (XRF) is the most accepted analytic technology for grade control in mineral production and processing. Bruker's wide range of XRF instrumentation can meet any need in production monitoring for mining in the goal of separating waste from ore.
