Hybrid Flotation Technology - An innovative technology for processing low-grade ores

Hybrid Flotation Technology - An innovative technology for processing low-grade ores

The flotation process is the heart of every mine – it contributes heavily to the profitability of the mining business. Due to a long tradition in ore beneficiation, Primetals Technologies offers innovations for processing low-grade ores, which guarantee a cost-effective approach to flotation cells.

Hybrid Flotation Technology of Primetals Technologies combines a pneumatic spray principle with a column method. The technology is based on the merging of feed pulp (slurry) and gas (air or nitrogen) in the mixing chambers of the ejector system before spraying it into the cell – with short retention times. This considerably enhances the frequency of contact between the gas bubbles and very fine particles – high enrichment factors and an increasing profit are the results. Additionally, the Hybrid Flotation Cell of Primetals Technologies does not require an impeller system, which means no wear and friction of the rotor or stator. The advantages of no moving parts are significantly low energy consumption and reduced maintenance. The Hybrid Flotation Technology of Primetals Technologies shows substantial lower gas consumption through the ability to create finer gas bubbles.

Circular Pelletizing Technology - The next step in efficiency

Circular Pelletizing Technology - The next step in efficiency

A new standard for a new flexibility: ultra-compact pelletizing plants from Primetals Technologies stand for maximum flexibility, excellent pellets quality, high energy efficiency as well as low overall investment cost.

Circular Pelletizing Technology from Primetals Technologies is the next step in the evolution of highly efficient, ultra-compact pelletizing plants. It is smaller by half than conventional plants and offers completely new flexibility in integration and pellet production. It frees you from rising costs for pellet supply – with the world‘s most compact pelletizing plant.

Sinter Plant - High performance and environmentally friendly solutions

Sinter Plant - High performance and environmentally friendly solutions

Sintering technology from Primetals Technologies ensures high and stable sinter quality for best blast furnace operation, high flexibility and low operating costs.

Requirements for availability, process quality and productivity of sinter plants are continuously growing, while at the same time a growing number of environmental regulations necessitate extensive investment. As plant designers, our job is to create concepts that offer the best possible solution to meet environmental requirements and economical needs simultaneously. Primetals Technologies, with its integrated process knowledge, is a leading full-line supplier of sinter plant solutions. Our technologies meet all local and market-specific requirements. With our “Pallet Width Extension Technology” and “Selective Waste Gas Recirculation” we are able to reduce the quantity of offgas in sinter plants by up to 50%. This significantly lowers not only environmental pollution but also energy consumption. Maximum emission reduction during sintering is possible – with Meros® plant solutions from Primetals Technologies.

This single-source capability forms the basis of fast project completion and start-up, for the complete range of solutions from small to ultra-large blast furnaces.

Corex® - Cost-efficient and environmentally friendly ironmaking

Corex® - Cost-efficient and environmentally friendly ironmaking

Corex is an industrially and commercially proven smelting-reduction process – unique to Primetals Technologies. Corex enables the cost-efficient and environmentally friendly production of hot metal from iron ore and coal.

In the Corex process, all metallurgical work is carried out in two separate process reactors – the reduction shaft and the melter gasifier. Since coking and sintering plants are not required for the Corex process, substantial cost savings of up to 20% can be achieved in the production of hot metal, of a grade similar to that of the blast furnace. Regarding environmental concerns, Corex plant emissions contain only insignificant amounts of NOx, SO2, dust, phenols, sulfides and, ammonia. Emission values are already far below the maximum values allowed by future European standards. Furthermore, waste-water emissions from the Corex process are far lower than those in the conventional blast-furnace route.

Finex® Environmentally safe ironmaking

Finex® Environmentally safe ironmaking

Finex is an innovative ironmaking process jointly developed by Primetals Technologies and the Korean steel producer Posco for the production of hot-metal – based on the direct use of fine ore and non-coking coal.

In the Finex process, fine iron ore is charged at the top of a cascade of fluidized-bed reactors where it is heated and reduced to direct-reduced iron (DRI) by means of a reduction gas – derived from the gasification of the coal – that flows in the counter-current direction to the ore. The DRI fines are processed to hot-compacted iron, transferred to a charging bin positioned above the melter gasifier and then charged into the melter gasifier, where melting takes place. The tapped product – liquid hot metal – is equivalent in quality to the hot metal produced in a blast furnace or Corex plant.

Midrex® – the world’s leading DRI production process

Midrex® – the world’s leading DRI production process

Midrex is an innovative ironmaking process, developed for the production of direct-reduced iron (DRI) from iron ores and primarily natural gas.

Midrex is a gas-based shaft furnace process that converts iron oxides – in the form of pellets or lump ore – into direct reduced iron (DRI). The Midrex technology is highly adaptive to our customers’ needs, which is reflected in a broad variety of configurations. The performance of Midrex plants typically exceeds nominal capacity ratings. This trend will continue with the implementation of new technologies such as oxide coating, oxygen injection, OXY+, centrifugal process gas compressors and our process optimization system. As a licensee of Midrex technology, Primetals Technologies has been successfully building Midrex direct reduction plants and is able to supply all sizes of packages right up to turnkey solutions. About one third of all Midrex plants worldwide have been built with significant involvement (e.g., consortium leadership) of Primetals Technologies.
