15. INSTALLATION PROJECT
1 – wastes charger
2 – crusher conveyor
3 – retaining construction
4 – impact crusher
5 – vibrating screens
6,7,8,9 – belt conveyors
10 – product containers
11 – de-dusting system

16. INSTALLATION PROJECT
• Wastes loaded from waste
stockpile by loader to charger
• From charger material is
directed to impact crusher M5
• After crushing material is led
to two-deck vibrating screens
• Fraction >31.5 mm is
redirected to impact crusher
• Fraction 5-31.5 mm (final
product) is put to product
container
• Fraction 0-5 mm („Secondary
Impact crusher M5: waste”) is directed to second
• Capacity 1,5 tph container
• Power 7,5 kW • Product containers periodically
• 1000 RPM cleared to product stockpiles

17. WP 5 Pilot investment by Örebo Univ. (P4)
A mobile unit for recovery of metals from various categories of
mining waste and metal-rich process residues
(1) Crushing/milling
(2) Leaching
(3) Recovery of elements from solution
in sequence:
• A combination of a jaw crusher and another type of mill
crushing the waste down to roughly 0.1 mm.
• A leaching apparatus designed to leach (using manipulated
water solutions) solid waste using high pressure and
temperature.
• A mixer-settler unit for recovery of metals by using liquid/liquid
extraction

21. THE PRINCIPLE OF OPERATION
- ELEMENTS AND CAPACITY
 Elements of investment (by now)
XRF MiniPal4 Chamber furnace
for chemical for material
characterization modification
of the samples
TGA-DT, DSC
for thermodynamic
reactions and material
optimization
 Capasity: so far only preliminary experiences . XRF: 20
min / sample; TGA-DT, DSC: 3 samples / shift, furnace:
1 heating / 1 kg / shift.
