Samplers FAQs

Achieving accurate unbiased samples for dry ore streams and slurries requires expert knowledge and top-of-the-range sampling equipment. Multotec has manufactured and supplied sampling equipment under license to Siebtechnik GmbH in Germany since 1987. With this knowledge and experience, more than 40 years’ experience in the mineral processing industry, and teams of dedicated and passionate metallurgists and engineers, we help mining houses achieve accurate, unbiased samples for both dry ore streams and slurries.

Using the latest research and developments we refine existing technologies and develop new products – always aiming to enhance speed to market and ensuring we produce consistent and reliable products. All of these make Multotec a leader in samplers and mineral sampling systems.

Mineral Sampling FAQs

Mineral sampling systems allow operators to understand and analyse the nature and quality of their mineral streams: a critical part of the overall mineral processing operation. Mineral sampling methods are divided into wet, primary and ancillary dry samplers, as required by your application.

What is sampling in mineral processing?
Sampling in mineral processing is used to estimate grades and contents of sampled materials. The aim is to evaluate resources; determine physical and chemical characteristics; and assess process feasibility. A wide range of mechanical parameters need to be optimised to ensure unbiased, composite mineral samples are collected.
What are the sampling techniques in mineral processing?
Material streams can be sampled through a range of sampling solutions, including belt cross stream samplers, cross belt samplers and wet cross stream mineral samplers. It’s important that your sampling technique is carefully matched with your unique ore characteristics and process feed properties.
What is Theory of Sampling?
Pierre Gy’s Theory of Sampling (ToS), expressed through over 250 scientific books and articles he wrote on the subject since the 1950s, remains the pinnacle of mineral sampling methodology today. It proposes formulae for achieving accurate material specimens from cross-belt and flowing streams. At its core, this mineral sampling theory describes a sample as ‘correct’ only if each fragment has the same statistical probability of being selected for the sample as every other fragment.
