Does the ash content in Gypsum affect its industrial application?

Yes. Ash content indicates the amount of non-combustible impurities remaining after burning. High ash levels can interfere with chemical reactions in plaster or cement manufacturing. Buyers must check the ash percentage against their specific process requirements to avoid contamination in the final product.

Is a mill test certificate mandatory for every shipment?

A mill test certificate confirms the physical and chemical properties of the material as produced. Many buyers require this document to verify that the shipped lot matches the agreed specification. It serves as proof of quality and is often a prerequisite for payment release.

How does particle size distribution impact mineral powder handling?

Particle size distribution determines how the powder flows, compacts, and reacts. Fine powders may require special handling to prevent dust hazards or clumping during transport. Coarser particles might settle differently in a container, affecting stability and unloading efficiency at the destination.

What is the role of the mineral export licence?

The mineral export licence authorizes the legal removal of raw materials from Czech Republic. It ensures compliance with national resource management policies. Importers must verify that the seller holds a valid licence for the specific commodity before finalizing the purchase to avoid customs seizures.

Why do fluorspar quotes depend on calcium fluoride percentage?

Calcium fluoride is the primary valuable component in fluorspar. Higher percentages command premium prices because they reduce the cost of downstream smelting processes. Quotes are tightly linked to the assay result, so even small variations in purity can significantly change the landed cost.

How does moisture content change the payable weight?

Moisture adds dead weight that provides no commercial value. Contracts often specify a base moisture level, and any excess is deducted from the gross weight. Buyers pay only for the dry weight of the mineral, making accurate moisture measurement critical for fair pricing.

What happens if scrap contamination is found in the lot?

Scrap contamination introduces foreign metals or materials that can ruin the smelting process. Buyers reject loads with excessive scrap because it requires additional separation steps or renders the batch unusable. Screening for contamination is a standard part of the acceptance criteria for mineral shipments.
