Sampling

Sampling methods for current commodities are accredited. Typical cargos sampled during marine vessel loading in the Port are:
• iron and manganese ores
• copper, lead and zinc concentrates
• coal and anthracite, etc

Sampling is performed in the Port or at customer sites where commodities are stored, such as at stockpiles, from conveyors, rail trucks, etc.

Sampling systems at mines are evaluated and tested to ensure fit for purpose functioning as part of the consulting services provided.
