PROCESS MINERALOGY
LABORATORY
Mineralogical analysis is used as a basis for the development of
beneficiation methods
• Mineralogical and geometallurgical research
• Mineralogical analysis is an essential tool in developing new
beneficiation methods
What we do:
Characterization of mineral products and environmental samples in
• Mining activities (green/brown field), ore prospecting, beneficiation
technology and smelting plants.
• Circular economy, side and waste streams of all sorts
Tools
• Scanning Electron Microscope (SEM) Mineral Liberation Analyser (MLA
• FE-SEM (MLA/QEMSCAN/AMICS): high resolution imaging, advanced
process mineralogy
• XRD: mineral identification and quantification using Rietveld method
• Raman microscope: e.g., Magnetite / Hematite , Li-minerals
(spodumene)
Technical facilities for sample preparation

MINERAL PROCESSING AT
BENCH SCALE
• Process chemistry research, grinding, beneficiation
testing, determination of hydrophobicity and
electrode potential.
• Our focus is on flotation method.
• Gravity and magnetic separation and thickening is
also conducted as laboratory studies.
• Next step is minipilot- or pilot-scale tests.
• We have testing facilities suitable both for normal
and high-pressure leaching.
• Bioleaching has also been used to extract base
metals
• Our laboratory testing provides our customers with a
preliminary overview of the process required to
process their mineral deposit.

MINI PILOT PLANT
First study in a continuous process
after bench scale results
• Sample size 400 – 2,000 kg
Samples types:
• drill cores, ore sample etc.
Samples are pre-crushed to feed size of
3 - 6 mm
Facility was originally designed and
constructed in a sea container
Feed capacity 10 - 50 kg/h.
3.6.2021
PILOT PLANT Process: • Processes can easily be adapted to capacity ranges from 0.2 tph up to 5 tph • Sample sizes typically from 20 to 300 tonnes • Plant automation and process control of a high level, together with automatic sampling systems, ensure the highest quality results Objectives: • Testwork for feasibility studies of new ore deposits • Process development for existing plants • Develop comminution and benefication methods • and equipment for industry • Generate process information for plant design • Assist in bankable feasibility studies 3.6.2021
10 CRUSHING PLANT Crushing laboratory Crushing plant • Capacity around 40 tph. • Storing area for homogenised feed. Tools and equipment • Jaw crusher: Lokomo C 63 B, 45 kW • Gyratory crushers: Lokomo G158, G108,´75 kW each • Horizontal Shaft Impactor: 2 x Hazemag AP-S 0604,15 kW • Vertical Shaft Impactor: Sandvik B5100 • Vibrating screens: Lokomo B130, B230, 7.5 kW each • High pressure roller mill: LRM, Ø 300 x 100 mm, 2 x 11 kW 3.6.2021
11 RESULTS Results from test runs indicate the commercial value and process efficiency of a mineral deposit Test runs gives an overview on how efficient a full-scale beneficiation process will be Estimation on the commercial value of the mineral deposit. Intermediate and end products, such as concentrates and tailings, that can be used in further studies. Assisting in developing key solutions for the circular economy The applicability of mineral processing methods to environmental and recycling-related operations has been proven by several studies. The processes used to extract minerals from ore can be used in the remediation of contaminated soil and separating recyclable metals from industrial slag and other side streams and wastes 3.6.2021
