Other Notes
Bi and all other elements should be each 0.10% max, with the exception of WO3, which should be 0.05% max and Si which should be 6% max. Unless contracted at the time of negotiation, other elements above do not give Buyer right to reject and may only form the basis for further discussion in the event material assays outside of these maximum levels.
Note: Material with Pb 0.05% max. and also with size 0 – 1 mm, 90% min. is available.
Packing: 0 – 4mm is usually packed in big bags, with 0 – 1 mm supplied in drums.

Inspection Schedule
Open all containers, note any different markings, forms or indications of heterogeneity.
Sampling Schedule
If there are no indications of material heterogeneity then sample on an incremental basis of 10 MT sub lots. If heterogeneity is suspected select the incremental groups accordingly but in sublots of 10 MT or less. Each open big bag or drum should be sampled from top to bottom using a sample spear, the increments thoroughly mixed and reduced to bulk sample size.
Sample Preparation
The bulk samples is further prepared by drying, screening, size reduction to produce a quality sample. The laboratory would normally determine the oil content on the quality sample. Where heterogeneity has been observed, or if necessary, the sub lots can be prepared individually as opposed to creating a composite sample.
