Mineral Processing FAQs | Multotec
Mineral processing solutions aren’t bought off the shelf – they need to be engineered into a solution customised to your unique beneficiation requirements. That’s why knowledge, experience, innovation and engineering skill are just as important as proven, high-quality and reliable mineral processing equipment in optimising your plant’s overall cost per processed ton. At Multotec, we have a dedicated and passionate team of metallurgists and engineers driven by designing and integrating robust mechanical solutions in line with the latest research and developments in extractive metallurgy to increase your plant’s productivity and profitability. With operations in over 20 countries across 6 continents, there’s literally a world of knowledge behind your Multotec mineral processing equipment.

Mineral Processing Equipment
Mineral processing equipment includes a wide range of machinery and products designed to process ROM stockpile material into a refined mineral unit. These solutions include screening systems, gravity concentrators, hydrocyclones, magnetic separators, filter presses and industrial centrifuges.
How is the mineral removed from the ore?
Mineral processing generally involves four broad processing operations: comminution (primarily crushing and grinding), sizing (with screening and hydrocyclones), concentration (e.g. gravity concentration, flotation and centrifuges) and dewatering. Each mineral type is extracted from ore through a unique beneficiation process across these four areas of mineral processing.
What is mineral processing and extractive metallurgy?
Extractive metallurgy is the field of metallurgical engineering concerned with the processes and methods of extracting metals from their natural mineral deposits. Mineral processing is 1 of 4 main categories of extractive metallurgy, alongside hydrometallurgy, pyrometallurgy and electrometallurgy.
What is dewatering in mineral processing?
Slurries enable ore to be handled and transported more efficiently. Some ores need to be watered for further processing. But ultimately, these slurries need to be dewatered and the ore/mineral isolated from the water content. The main processes used in dewatering are screening, sedimentation, filtering and thermal drying.

What is a DMS cyclone?
A DMS (Dense Medium Separation) cyclone is a cyclone which sorts two types of solids based on their differing densities. A mixture consisting of fine medium in the form of magnetite (Fe3O4) or ferrosilicon (FeSi) mixed with water is fed into the cyclone with the solids to be sorted. The lighter particles exit the cyclone through the vortex finder and overflow and the heavier particles exit the cyclone through the spigot (Apex).
DMS cyclones are used in many mineral types to sort or upgrade the product being produced. It is normally associated with mineral processing plants treating diamonds, coal and other minerals.
What industries does Multotec supply cyclones to?
While it is in mineral processing that Multotec cyclones have really made a name for themselves, we also supply cyclones to other parallel industries such as manufacturing, food processing, and so on.
Can you supply me a cyclone specific for my needs?
Yes, Multotec has a wide range of standard cyclone solutions ranging from units of 25 mm diameter to larger units of 1 450 mm diameter. Multotec cyclones range in materials of construction to offer suitable solutions for various applications. The cyclones are furthermore selected and sized by an experienced process team to best suit clients’ needs. For specialised applications Multotec can custom design and manufacture a cyclone to meet the application.
Do you supply cyclones world-wide?
Yes, Multotec cyclones are distributed across the world. From our head office in South Africa, we have various branches and agents world-wide to ensure you get the best support and coverage for your plant cyclones.
Do you supply cyclone training?
Multotec carries out cyclone training for our customers and can customise this to best suit clients’ needs and requirements.
What is the advantage of buying a Multotec cyclone?
By buying a Multotec cyclone our clients have peace of mind knowing that they have an industry-proven product that has been carefully selected to best suit operational and client requirements. Multotec also supplies clients with technical support and service, with full spare parts backup.
