NW products are prepared on the basis of two main criteria: granulometry and physical specifications.

1. Granulometry, the first process applied on run of mine talc, is screening to separate lumps from fines. These two fractions will have a different process downstream.
   •  Lumps will be cleaned and graded through hand-sorting.
   •  Fines will have to undergo specific process which includes several screening phases with intermediary stages where fines and grains are individualized to be cleaned.
2. Specifications, settled as per table below, are assessed and enforced by NW QC team with inhouse lab equipment.
