CIME develops innovative, tailor-made and integrated solutions, always more respectful of the environment by relying on 4 clusters:

  • Studies
  • Testing laboratory
  • Industrial pilots
  • Analytical laboratory
SamplingSampling

Main step in the estimation of mining reserves

Sampling is an essential step in estimating deposit reserves or conducting representative tests in an ore processing process.

Sampling consists in obtaining a reasonable number of representative samples of a deposit or a pile of several thousand or millions of tons of ore by means of direct sampling, reductions or successive divisions.

CIME engineers use Gy's theory to optimize the different steps of the process.

Process Design and managementProcess Design and management

Customized processes design for industries

The teams carry out studies which integrate the development and the fine-tuning of processes for the implementation of pilots. These tests are carried out under real-life operating conditions to address the customer problem. The fields are variable, such as elements from non-nuclear residues (urban mine...). In the nuclear fields, CIME authorizations allow handling of up to 34t U, 2t Th and 800g U235 enriched up to 5%.
