What is the essence of radiometric ore dressing method? |
| Radiometric dressing — separating of useful minerals from useless rock, based on minerals quality to emit radiations (emission-radiometric methods) or weaken them (absorbing-radiometric methods).
Natural minerals radioactivity, their luminescence and so on are used in emission-radiometric methods.
X-ray, neutron, and gamma-emission are used in absorbing-radiometric method. |
Does the equipment for radiometric dressing manganese ore exist? Initial content Mn - 18-20% |
| Manganese ore have a great variety of types according to substance structure, admixtures, granular-metric structure and other factors.
Great-scale tests of XRS technology of different kinds of ores have been made for the following deposits:
- Porozhinskoe, Mazelskoe, Nikolaevskoe (Krasnoyarsky krai, RF)
- Gromovskoe (Chitinskaya area, RF)
- Tur, (Kazakhstan Republic)
- Ushkatyn (Kazakhstan Republic).
Positive results, proving the possibility of getting of qualitative metallurgical concentrate with certain manganese content indexes, module (ratio Mn/Fe) and admixtures content, have been got nearly everywhere.
For example, according to technological ore properties, one can get different kinds of concentrates: more than 40% (45%) manganese, at the level 30-35% manganese, i.e. according to the task and demand. |
What are the main separator parts and their functions? |
| According to the functional principle , the separator consists of the following structural units:
- measure-control system (MCS)
- ore feed apparatus (OFA)
- executive mechanisms (EM)
- separation products receiver (SPR)
The separator Measure-control system (MCS) (main devices):
EDB — Electronic detecting block is used for the registration of characteristic X-ray emission , stimulated by the primary resource (X-ray tube, PXAS ) in analyzed ore pieces , for apparatus spectrum formation and connection with a control computer.
PXAS — Portable X-ray apparatus (small-gabarit) is used for primary X-ray emission generation
Control computer — provides main separator units work control with the suitable software
Mechanical separator units:
OFA — Ore feed apparatus provides simultaneously the following functions:
- receiving and accumulation of primary ore in the receiving bunker
- ore extract from the receiving bunker with certain productivity with following formation of the mono-lay at the end of vibro-feeder tray
- removing of impossible to sort small pieces in the zone of fire-bars sieve distributor
- ore feed onto distributor trays with successive ore distribution into the flow of pieces following one after another (stream regime)
EM — Executive mechanisms is used for mechanical trajectory deflection of pieces from ore flow flight.
