4. Results of an industrial operation

4.1 Processing results and plotting curves

The following data are available after an industrial operation:

• the mass distribution of heavy and light metals and their respective contents ;

• densimetric analysis of heavy and light materials.

We use calculations to check the validity of the sampling by comparing the reconstituted feed with the actual raw feed.

The results can then be represented in two types of curves.

• Washability curves

  The densimetric curves of the reconstituted feed and those of the outgoing products are plotted on the same diagram (figure
