How do chemical assay and alloy designation differ for a Copper listing?

The chemical assay states the percentage of pure copper present in the lot, which determines the base metal value. The alloy designation specifies which other elements are added, such as zinc or tin, to create a specific material property. A buyer must check both because a high purity assay means nothing if the alloy mix does not match the intended casting or extrusion process.

What does a mill test certificate prove for Iron Alloy?

The mill test certificate provides the documented chemical analysis of the specific batch of Iron Alloy being shipped. It confirms that the manganese, silicon, and carbon content fall within the agreed tolerances. This document is essential for the destination port to clear the goods and for your quality team to verify the material will react correctly in the smelter.

Why does moisture content matter for Manganese Ore shipments?

Moisture content adds dead weight to the shipment, meaning you pay for water that provides no industrial value. High moisture can also cause the ore to cake inside a container, making it difficult to unload. You should verify the moisture percentage in the assay to ensure you are paying only for the dry weight of the manganese content.

What is the risk of gold dust particle size distribution?

If the particle size distribution is too coarse, the gold dust may not dissolve efficiently in your refining solution. If it is too fine, it may be lost as dust during handling or transport. You need the seller to specify the mesh size or micron range to ensure the lot matches your refinery's input requirements for optimal recovery rates.

How does scrap-contamination screening affect Lithium Ore entry?

Destination ports screen Lithium Ore for non-lithium waste materials that could disrupt the processing plant. If the lot contains significant impurities or mixed scrap materials, it may be rejected at the border. The mill test certificate should detail the purity level, but physical screening at the port verifies that the physical lot matches the documented purity.

When does a quote for Copper Ore become invalid?

A quote for Copper Ore becomes invalid when the global index shifts beyond the tolerance window agreed with the seller. Since copper prices track the London Metal Exchange, even small daily moves can exceed the margin. Sellers usually hold quotes open for only a few days, so you must confirm the order quickly or request a new price based on the current index.

Does density determine container usage for Iron Ore?

Yes, density determines whether the container fills by weight or by volume before it is full. Iron Ore is very dense, so you will likely hit the maximum weight allowance long before the container is physically full. This means you cannot stack other lighter goods in the same container, and you must pay for the full weight capacity regardless of the empty space.
