Transport the crushed underscreen to the first magnetic separator 6, transport the concentrate selected by the first magnetic separator 6 to the second cylindrical screen 7, and transport the tailings selected by the first magnetic separator 6 to the second A jig 8; the oversize of the first cylindrical screen 3 is transported to the second crusher 38 through the third belt conveyor 40, and the first iron remover 39 is installed above the third belt conveyor 40, and the first iron remover 39 sucks The iron is transported to the third crusher 36 through the fourth belt conveyor 37, and after being crushed by the third crusher 36, it is transported to the second magnetic separator 35; the concentrate selected by the second magnetic separator 35 is transported to the second cylindrical screen 7. The tailings selected by the second magnetic separator 35 are transported to the second jig 34; the oversize material sorted by the second cylindrical sieve 7 is discharged into large iron pieces, and the undersize material is passed through the fourth magnetic separator 10 points to select the iron powder; the underflow after the first jig 8 and the second jig 34 sorting enters the third magnetic separator 9 to select the iron powder, the third magnetic separator 9 and the fourth magnetic separator The tailings selected in 10 are sent to the first shaker 18 and the second shaker 17 respectively, and the concentrate separated by the shaker is sent to the fifth magnetic separator 29, and the iron powder is separated again, and the shaker is separated The selected tailings are transported to the third settling barrel 12;
[0025] The copper recovery system includes a first vibrating feeder 32, a third cylindrical screen 31, a fourth crusher 30, a third shaker 28, and a pit 27; the recovery of copper can be realized through the copper recovery system, and the specific recovery The process is as follows:
[0026] After being sorted by the first jig 8 and the second jig 34, the materials in the tank are taken out and enter the gold selection platform, and after drying and sorting, the first vibrating feeder 32 conveys the third cylindrical sieve 31. The oversize of the third cylindrical sieve 31 is large copper, and the undersize of the third cylindrical sieve 31 is sent to the fourth crusher 30 for crushing, and then sent to the fifth magnetic separator 29 for further separation Iron powder is extracted, and the tailings selected by the fifth magnetic separator 29 are transported to the third shaker 28 to separate the broken copper, and the tailings separated by the third shaker 28 are transported to the pit 27;
[0027] The aluminum recovery system includes a leaping screen 21, a first settling barrel 20, a first vortex separator 23, a fifth crusher 24, and a second vortex separator 22; aluminum recovery can be realized through the aluminum recovery system, specifically The recycling process is as follows:
[0028] The material is sorted by the first jig 8 and the second jig 34, and the overflow part is transported to the jumping screen 21, and the sieve hole size of the jumping screen 21 is divided into 0-2mm and 2-8mm according to the particle size of the material , 8-30mm, >30mm four specifications, 0-2mm material enters the first settling barrel; >30mm material is hand-selected to sort out metal; 8-30mm material is transported to the first eddy current separator to select aluminum, The tailings sorted by the first vortex separator are transported to the fifth crusher to make medium sand; the 2-8mm material is transported to the second vortex sorter to select aluminum, and the tailings of the second vortex sorting are medium sand ;
[0029] The sand making system includes a second settling bucket 25, a first high-frequency screen 20, a large settling bucket 13, a second high-frequency screen 26, and a third high-frequency screen 16; the overflow part of the material in the first settling bucket 20 is conveyed In the second settling bucket 25; the underflow of the first settling bucket 20 is delivered to the first high-frequency sieve 20 for screening, the screened material is fine sand, and the screened material is transported to the pit; the third settling bucket 12 The overflow part of the material is transported to the large settling tank 13; the underflow of the third settling tank 12 is transported to the third high-frequency screen 16 for screening, and the sieve of the third high-frequency screen 16 is fine sand, and the third high-frequency screen 16 The undersize is delivered to the pit 27; the material in the pit 27 is pumped into the second settling barrel 25, and the overflow of the second settling barrel 25 is delivered to the large settling barrel 13, and the bottom flow of the second settling barrel 25 Transport to the second high frequency sieve 26 for screening, the oversize of the second high frequency sieve 26 is fine sand, and the undersize of the second high frequency sieve 26 is transported to the large settling bucket 13;
[0030] The tailings treatment system includes a large clear water tank 14 and a filter press 15; the overflow of the material in the large settling tank 13 is transported to the large clear water tank 14 for recycling and reuse, and the bottom flow of the large settling tank 13 is transported to the filter press 15 to squeeze out the water And be transported to big clear water barrel 14, filter cake recycling.
