Mining & sorting

Know the source.
Understand the preparation.

Sherwan geology, underground access and manual sorting explain how our Pakistan-origin raw material is prepared.

Dolomite-hosted talc.
Underground access.

Blanc Fixe’s Sherwan layout includes seven access tunnels within the same mining concession and talc-bearing geological system. Production is identified by tunnel and lot as it moves into preparation.

Geological context helps explain the source. Material variation still needs grade selection and representative assessment.

From source to prepared lot

01
Identify the source
Record origin, tunnel production and material stream.
02
Screen and hand-sort
Separate sizes and visible material selections.
03
Keep the lot identified
Connect the preparation lot to samples and shipment records.

Manual selection

Screen for size.
Sort for visible selection.

Screening separates lumps and smaller fractions. Hand sorting removes visibly unsuitable pieces and segregates the selected material. Size alone does not establish grade.

Visual sorting cannot quantify purity, establish an optical result or demonstrate the absence of asbestos. Those questions need representative sampling and appropriate laboratory methods.
