Complex sulphide ores

Complex sulphide ores contain more than one single valuable metal sulphide mineral each to be separated into its own individual concentrate. The most common method is flotation, using various sulphydryl collectors, pH control, and a selection of depressants. Generally, the ore is ground in two stages after which the ground pulp is subjected to conditioning followed by individual flotation stages to produce different concentrates that are then dewatered to optimum transport moisture.

Porphyry copper ores

The main sources of global primary copper are porphyry copper mines; the largest typically treat tens of millions of tons of ore annually. The requirement to handle these massive capacities demands large-scale equipment, meaning fewer units with a smaller footprint to conserve energy, reduce maintenance and manpower costs, and through functional automation systems limit the environmental burden.

Iron ores

Where direct shipping of iron ore lumps is not possible due to the low grade, iron ores are mainly processed by crushing, grinding, screening, classification, gravity separation, magnetic separation and flotation technologies. The main iron minerals, magnetite and hematite, are separated from gangue minerals using the following core technologies: for magnetite ores, low intensity magnetic separation and flotation to remove mainly sulphides and silicates; and for hematite ores, scrubbing, desliming, gravity separation, high intensity magnetic separation, and flotation to remove mainly silicates including clay.

Outotec supplies complete beneficiation plants for different types of iron ores globally. In order to develop a process flow sheet, the mineralogical, physical, and chemical properties of the raw material generally need to be defined at first. Furthermore, it is essential to carry out laboratory and pilot scale test work. Based on extensive test work, Outotec is able to give process guarantees for the process solutions we deliver.

The demand for ever increasing capacities requires reliable and high throughput machinery. The Outotec range of equipment meet the requirements of any application. Outotec offers an extensive selection of grinding mills, flotation cells, and dewatering equipment with a high level of automation and process control to optimize plant performance.

Grinding mills

Outotec's comminution equipment includes Autogenous (AG) mills, Semi-autogenous (SAG) mills, rod mills, ball mills, and pebble mills. A wide variety of mill designs are available to suit customer requirements in either greenfield projects or existing operations as expansions or upgrades.

Outotec expanded its grinding mill product family with the Outotec High Intensity Grinding MillTM (Outotec HIGMillTM) for fine, ultra fine, and regrind milling applications.

Proprietary equipment for mineral processing solutions

The Outotec Turbo Pulp Lifter (TPL) makes the grinding process more efficient in SAG and AG mills, as the primary grinding process can be intensified. TPL is an environmentally friendly technology and is used to ensure efficient material transport to achieve high energy efficiency. Better energy efficiency in the grinding process can create significant cost savings in the concentration process.


Flotation machines

Outotec sets new standards in superior flotation performance; aeration and mixing, froth manipulation, and recovery, for every flotation task. Our flotation solutions are tailor-made to customers' needs; be it a question of flotation packages with support services, modular process sections or concentrator solutions. FloatForce, Outotecs innovative flotation mechanism, improves metallurgical performance and reduces the energy consumption of flotation operations. This rotor-stator design can be directly retrofitted to Outotecs OK, TankCell and SkimAir flotation cells to improve their mixing profiles and solids suspension.

Every stage in the flotation circuit is customized, be it roughing, scavenging or cleaning. The Outotec offering consists of the worlds widest range of flotation cell sizes from 5 to 500 m3 universally known for excellent metallurgical selectivity and energy efficiency. The new TankCell e500 provides lower capital expenditure due to lower equipment costs, savings in plant footprint, less installation work with less auxiliary equipment, lower energy consumption, and fewer units per installation results in fewer components and spare parts, and less maintenance.

Thickeners

Outotec is a global leader in the design, fabrication, and supply of thickening and clarifying solutions for the minerals industry. The Outotec High Rate Thickener has pioneered thickening and clarifying methods around the world.

A number of significant thickening advances include low profile triangular rake arms to reduce rake torque, Outotec Directional Autodil and Outotec Turbodil the worlds first thickening systems to auto-dilute feed, thereby optimizing performance and flocculant consumption, Outotec FrothBuster deaerator to reduce the amount of froth forming on the surface of thickeners, automatic de-scaling of thickener rakes, and the complete redesign of thickener drives to use low-cost, efficient epicyclic gearboxes. Outotec Vane Feedwell incorporates a cutting-edge design and is the major innovation in the thickening industry. One of many design features is the interconnected upper and lower zones.


Filters

Outotec is a leading industrial filtration solutions provider with full after sales services for solid-liquid separation. Mining and metallurgy, chemical process, and related industries benefit from our high-efficiency process technologies, products, and solutions.

Outotec filtration technologies are based either on over-pressure, including automatic vertical pressure filters, horizontal filter presses, and polishing filters, or on under-pressure, including horizontal vacuum belt filters, ceramic disc filters, and conventional vacuum disc and drum filters.
