Ore feeding, its disintegration and classification to size (section № 1)
        The ore is fed through a bin (2) to a grizzly screen (3) with 50 mm between bars by means of a loader. Moving along the bars the oversize is being intensively washed by jets of water. The washed oversize runs to a conveyer (5) and goes to waste. The undersize (3) with water runs to a sump of pump (4) and then to a disintegrator (6). After disintegration product goes to a screen (7), where three sizes are extracted: -50+20, -20+2 and -2 mm. The -50+20mm size is fed to the conveyer (5) and then goes to waste, the -20+2mm size is fed to a thickener (20) for receipt of thickened tailings (approx. 75-80% of coarse one). The -20+2mm size is considered to be the main productive size which is fed to upgrading.
Gravity concentration of the -20+2 mm size (section № 2)
        The first concentration of material of -20+2 mm size is made in jigs according to the technology named ‘backwards jigging’. Due to this technology it is possible to receive values as equal to medium hard concentration in hydro-cyclones with less operating cost. The main advantage of the ‘backwards jigging’ technology comparing with medium hard concentration is that there is a high volume of hard fractions in raw material (density is 3,0 tonnes/m3 and higher). For example, at more than 10-15% of hard fractions in raw material the use of medium hard concentration becomes unprofitable and ineffective, but at the same time the ‘backwards jigging’ technology concentrates easily the same material with high values.
        Although, the prime advantage is evident at processing of shore sand containing significant volume of coquilles (snails). In this case the use of the medium hard technology is difficult and ineffective because snails full of ferrosilicon get into concentrate and because of the difficulty to regenerate them (loss of ferrosilicon increases in some times).
       So, prepared raw (washed and classified) material goes to jig 9, which tailings are dumped, and after dewatering process in the device 10 go to waste by means of a conveyer. Undersize concentrate -5 mm after the jig 9 and oversize concentrate -20+5 mm through a dewatering device 11 run to final concentration section. Undersize concentrate of the jig 9 by means of a pump 12 and a hydro-cyclone 8 is gone to the beginning of the process, i.e. to the jig 9.
Final concentration of jigging (section №3)
      Undersize and oversize concentrates of the jig 9 go to the screen 14 with 2, 5 and 10mm openings. Sieved product +10mm goes to an ore-sorting table 15 for visual contact of them. Products -10+5 and -5+2mm run to X-ray separators 16, 17, 18 and 19. Final concentration section is situated in a closed room with limited access and provided with built-in conditioning and emergency power supply for alarm, lighting and locking devices.
Power supply of the plant (section №4)
      Diesel-generator of 60 kW power mounted on the separated frame is used to supply energy for all the sections. The bin of 7,5 m³ for oil and control panel desk with protecting and alarm fitting
Dewatering of product less than 2mm and formation of circulating water (section №5)
      All the products of -2 mm grain size go to the dewatering section, which consists of some package-type thickeners 20 connected in series. Thickened part by means of a special a peristaltic pump 21 goes to waste, but water part is to the bin for circulating water, from where it is separated to sections. So, volume of water got to technology from a resource (river, lake, water well) will be determined by its consumption with dump tailings, in general, with -2 mm grain size and also the consumption linked to vaporization. For receipt of fresh water there is a 5 m³ bin (22).
Life-support section (section №6)
      Life-support section is presented as a complex of rooms for 4 persons: kitchen, bedroom, WC, laundry. All this is mounted in a closed wagon-house. The wagon-house is provided with conditioning, house hold appliances.
