Crushing Grinding Splitting of Samples for Testing/Analysis

Entrust your samples to a laboratory with proven expertise and state-of-the-art equipment for crushing, grinding, or sample splitting. Our laboratory can meet your requirements for industrial testing or analyses.

    • Scale up an industrial crushing or grinding facility by determining, for example, the Work Index or the Particle Size Distribution (PSD) of an ore
    • Prepare several homogeneous samples with a defined particle size (mesh) to study the performance of a processing method (leaching, liquid/solid separation, flotation, etc.)
    • Obtain finely ground and representative subsamples from coarse samples, intended for the requested analyses, including those required for mineral resource or reserve evaluation
    • Benefit from a customized sampling plan designed by our engineers, defining the optimal sequence of crushing, grinding, splitting, and sieving operations to be performed with our equipment
    • Perform mechanical preparation tailored to your objectives:
      • Crushing and grinding to achieve the target particle size
      • Sample preparation including splitting for analyses or process testing
      • Determination of key parameters (Work Index, PSD) for sizing your facilities
    • Work in complete safety: our dedicated laboratories are equipped with dust-extraction systems and ergonomic equipment to protect operators
    • Ensure that samples are prepared using a methodology representative of the process to be implemented
    • Have confidence provided in our sample preparation
