The run-of-mine feeding the plant goes through several operations:
-Sampling and analysis for quality control of the ore
-Mechanical preparation of the product reducing its size followed by a screening operation
-Dry beneficiation of Manganese by a pneumatic separation unit classifying by particle size and density factors.
Quality control is done through the whole process from the mine development to the final product, including the extraction and the processing of ore.
SACEM has an equipped laboratory to monitor quality along the production process.
