Lead-zinc ore beneficiation production line
The natural world is often lead zinc ore symbiotic together, are generally mineral flotation with due process. I.e. after crushing the ore to a particle size selected to a certain other low-grade waste rock large dense media, then the flotation process The ore that has been enriched. Heavy medium beneficiation is generally divided into four steps: ore preparation, second, selection of heavy medium suspension of galena, third, heavy medium for removing two products on the sieve, and fourth, recycling of heavy medium. In the first step, the ore of -25 mm is sieved, and the sieved material of less than 4.5 mm is dehydrated and sent to the grinding. The product on the sieve enters a shallow and wide chute, the bottom of the tank is a dewatering sieve, and the dehydrated product enters the belt. Sorted in a pyramidal heavy medium concentrator with a promotion ore discharge device, the floating material (ie abandoned tailings) enters the medium along a chute to remove the heavy medium on the sieve, and then enters the silo. The sinking object falls on the corner. In the lower part of the cone chamber, the dewatering bucket is transported out in the chute and then into the medium removal screen. The heavy medium on the ore is removed from the first two sections on the screen, and washed on the third and fourth sections. The heavy medium attached to the ore, the fifth section of the sieve is used to remove the washing water. The enriched ore after washing is put into the warehouse. The heavy medium removed by the medium is removed by the medium, and the material larger than 0.5 mm is removed by vibration, and In this sector, the sieve returning medium is removed from the sieve, and the sieved product is divided into three sections by a distributor. One of the large parts is returned to the heavy medium concentrator, and a small department is sent to the flotation machine to float the galena and return to the medium for storage. The weight of the heavy medium (galena) used for heavy medium ore dressing is 2.92 and the viscosity is 1.45. The grade of galena used to prepare the heavy medium is higher than 72% Pb to ensure that the viscosity of the resuspension is not large. When the content of fine float galena in the heavy medium is large, the adhesion is too large. When the coarse particles are too much, the sticking is too low, and the weight of the dry lead ore lost by one ton of waste rock is 0.03 kg.
