Sample collection, reduction, division while maintaining rep.
An essential step in the characterization of resources.
-
Many mining projects have failed due to poor field sample selection or an inadequate sampling plan.
The difficulty lies in obtaining reasonable size samples, representative of a deposit or heaps of several thousand (or millions) tons. Improper sampling can lead to major errors in estimating the reserves of a deposit, defining a process or sizing equipment.
CIME experts know the rules to be followed when reducing the size and dividing the samples, using Gy's laws to optimise these different steps and assess errors.
CIME acts at the customer's site to define, monitor or carry out the sampling operations. Then, in a second step, the sampling plan is established and crushing and screening operations can be carried out either on site or at CIME depending on the tonnages to be processed.
In Bessines, CIME has a wide range of equipment for reduction (crushers, mills), division (sifters, riffle dividers, rotating dividers, etc.) and characterisation (laser or optical granulometer, image analyser, etc.).

- Recognised expertise in sampling and error calculation
Sampling is an essential step in correctly estimating the reserves of a deposit or in conducting representative tests to define an ore treatment process. Over its 40 years of existence, CIME has defined the processes of all Orano mining projects in the field of uranium and gold, and for other activities such as the treatment of polluted soils.CIME services allow:
- To be assured that the analyses intended to estimate the reserves of a deposit have been carried out on samples perfectly representative of this deposit.
- To be assured that the tests intended to define an ore treatment process will have been carried out using composites representative of the area to be studied.
- To have an estimate of the potential sampling error associated with the proposed sampling plan.
