选矿工艺方案说明1）破碎筛分系统原矿堆存于原矿堆场，采用铲车上矿。原矿

Description of the beneficiation process plan <br>1) The <br>raw ore of the crushing and screening system is stored in the raw ore yard, and the ore is loaded with a forklift. A trough feeder is installed at the bottom of the raw ore silo to feed the ore to a jaw crusher for coarse crushing. The raw ore head needs to be less than 480mm in size. After the first crusher, the fineness reaches about 50mm. The coarse crushing is discharged through a belt conveyor. The second-stage cone crusher is used for fine crushing. After the second crushing, the fine material is transported to the vibrating screen through a belt conveyor for screening. The fineness of the under-screen is about 20mm and enters the fine ore bin. The upper ore is screened by the No. 2 belt The conveyor is returned to the three-stage cone crusher for fine crushing. The maximum fineness of the three-stage fineness is less than 150mm, and the discharge fineness is about 20mm. After crushing, the ore is also sent to the vibrating screen through a belt conveyor for screening. The under-sieve ore belt conveyor is transported to the powder ore warehouse for storage.

Description of the mineral process<br>1) Broken screening system<br>The original ore pile is stored in the original ore yard and the mine is mined by forklift. The original mine silo bottom slot feeder, to the mine to a jaw-type crusher for rough crushing, raw ore stone feed particle size needs to be less than 480mm, after a section of crusher, fineness reached about 50mm, rough ore through the belt transporter two sections of cone crushing Machine to carry out fine-breaking operations, secondary crushing after the fine material through the belt conveyor transport to the vibration sieve for screening operations, the fineness of the screen is about 20mm, into the powder warehouse, sieve on the mine from the No. 2 belt transporter back to the three-segment cone crusher for fine-breaking operations, The maximum feed fineness of the three segments is less than 150mm, the discharge fineness is about 20mm, and the ore is also sent to the vibration screen through the belt conveyor for screening. Sieve the mine belt conveyor and transport it to the powder warehouse storage.

Description of beneficiation process plan<br>1) Crushing and screening system<br>The raw ore is stored in the original ore yard and is loaded with forklift. Trough feeder is set at the bottom of the original ore bin, and the coarse crushing is carried out from the feeding to a jaw crusher. The feeding granularity of raw ore stone shall be less than 480mm, After passing a section of crusher, the fineness reaches about 50mm. The coarse crushing and discharging ore is carried out through the belt conveyor section II cone crusher for fine breaking. After the secondary crushing, the fine material is transported to the vibrating screen through the belt conveyor for screening. The fineness of the lower screen is about 20mm, and enters the powder bin. The ore on the screen is transported back to the third cone crusher for fine breaking. The three section fineness is the most The fineness of large feed is less than 150 mm, and the fineness of discharge is about 20mm. After crushing, the ore is also sent to the vibrating screen through belt conveyor for screening. The belt conveyor under screen is transported to the powder bin for storage.<br>
