Advantages of hard rock g falcon type centrifugal concentrator

g recovery plant for sale: centrifugal concentrator for jan 18, 2019 · when you want to efficiently recover fine g from g bearing ore, you need a centrifugal concentrator (cc). for example, a 13 tph (tonnes per hour) unit will handle both alluvial and hard rock material. one method with alluvials is to use a scrubber/trommel that washes and sorts the feed before it enters the centrifugal concentrator. g gravity concentrator knelson concentrator,falcon stlb g concentration separator is kind centrifugal concentration equipment. it can be used not only for placer g mining, but also for hard rock mining to recover the natural g, replacing amalgamation. it is also used to recover g from the tailings. since 1985, three models of g concentration separator have been developed. equipment to recover g without chemicalsthe i350 is a family member of the falcon gravity concentrators g mining equipment which has revolutionizing the world of alluvial g mining and dredging the same way its little brother, the i150, has impacted the world of hard rock mining. centrifugal concentrator henan deya machinery co., ltd.mar 22, 2021 · centrifugal concentrators consist of a vertical rotation bowl with a series of concentric rings that trap the g. a centrifugal force is applied on the ore particles, in such a way that this force is 60 (in the case of knelson) to 300 (in the case of falcon) times higher than the gravitational force. g recovery with centrifugal gravity concentratoroct 21, 2020 · here is how a gravity g concentrator (centrifuge) works as a separator: make sure the concentrator has been correctly assembled and that all bolts have been tightened. if required, attach a funnel to the material feed inlet. if necessary, connect a hose to the tailings outlet. 3g

list on minerals.seprosystems the performances of two labscale centrifuge concentrators, the 3 knelson and the 4 falcon superbowl, have been investigated. synthetic ores consisting in mixtures of quartz/tungsten, quartz/ilmenite/tungsten, and quartz/galena have been used. concentration tests with quartz/galena suggest that the concentration of the dense mineral can proceed by different ways according to the water flow: by infiltration or by plating of the dense mineral (low flow), by substitution between the light and dense minerals (intermediate flow) and by elutriation of the light mineral (high flow). tests carried out on the two gravity concentrators show that falcon gravity separation equipment achieves, on a wide range of particle sizes of the tungsten and on a wide range of water pressure, a better recovery of the tungsten (used to simulate g) than the knelson gravity concentrator. the knelson and the falcon have been used to concentrate less dense mineral than tungsten (galena). in both concentrato see full list on minerals.seprosystems among the separation processes, gravimetry is probably the cheapest one. thus it has to be considered first, of course if the liberation of the constituents is obtained by enough fragmentation and if the difference in specific gravity is high enough (taggarts criterium1). however, the efficiency of gravimetric separation becomes very poor when the particle size becomes very fine, around 100m. to overcome these limitations, new apparatus utilizing centrifugal force in fluidization have been recently designed and are used more and more in g recovery. these apparatus, knelson and falcon superbowl gravity concentrators, provide good recoveries for very fine particles up to 38m and finer. these gravity separators and their uses have been described in many papers. 2,3,4,5. the fundamental approach of the behaviour of mineral particles in these apparatus has not been studied until now. in our department, we carried out some fundamental research on fluidization and centrifugation with see full list on minerals.seprosystems the gravity concentrators used in the study are both the laboratory model: the 3 laboratory knelson and the falcon 4 laboratory superbowl (sb4). table 1 gives for the two concentrators the water flow rate as a function of the water counterpressure (cp). table 1: water flow rate (litre/minute) as a function of the water counterpressure (cp, kpa) for the 3 knelson and the 4 falcon (values do not include the water contained in the slurry). in order to obtain good and precise comparison, the experiments have been carried out with welldefined and pure mineral particles. the minerals used are described in table 2. we choose the quartz as an example of the gangue behaviour, ilmenite as a mineral of intermediate density, galena as a dense material to be recovered and metallic tungsten which has almost the same density as g (19.1 instead of 19.3). table 2: nature, density and particle size of the pure mineral samples used in the study. see full list on minerals.seprosystems the mixtures studied were: quartztungsten (100/10g) quartzilmenitetungsten (100/10/10g) quartzgalena (100/10g) for each test, a bed of quartz particles is first built in the bowl, until the excess of quartz is ejected out, in order to simulate the steadystate conditions. then the mixture (110g or 120g if 2 or 3 components) is fed as pulp into the bowl. at the end of the test, the concentrate remaining in the bowl and the tailings are collected, dried, and weighed and their composition is determined by gravity separation with heavy liquid (bromoform) or by using a mozley shaking table. see full list on minerals.seprosystems according to differences in the design of the two concentrators, the feeding of the ore in the fluidization zone is very different in the knelson than in the falcon. in the knelson, the ore is directly fed in the fluidization zone. in the falcon, the material is first fed in a segregation zone along the cone wall where the dense particles percolate through the bed of gangue to reach the wall of the bowl. at the end of this part of the bowl, the bed of materials is roughly composed of the lower layer containing most of the dense particles and an upper layer of gangue. then, this segregated material enters the fluidization zone. this way of feeding can have a strong influence on the recovery of heavy particles. in the knelson, particles are directly subjected to the water flow. so the smallest g particles can remain in the feed flow of pulp and do not enter in the interriffles spaces (irs). in this way, some of the g particles can bypass the irs and be lost. in the falcon, th see full list on minerals.seprosystems depending on the flow rate of the fluid across them, the light particles can be fixed (low speed), fluidized (higher speed) or elutriated (very high speed). the fluid velocity to get each of these states depends on the size and the specific gravity of the particles. the results of our experiments showed that the kind of states obtained in the knelson and the falcon depends on the cp water values and leads to different modes of concentration, which can also depend on the relative particle sizes of gangue and heavy materials. at low cp values, the gangue is blocked into the irs and gives a porous fixed bed. if the heavy particles are smaller than the voids of this fixed bed, they can percolate through the bed and reach its bottom where they are concentrated. this mode of concentration can be called concentration by infiltration. if the heavy particles are larger than the voids they cannot infiltrate through the gangue bed. however, due to the centrifugal force, they can be accumulat see full list on minerals.seprosystems figures 2, 3, and 4 show the recovery of tungsten in function of the cp for different particle sizes of quartz and of tungsten. on each figure the results obtained with the knelson and the falcon are presented. it clearly appears that the falcon achieves recoveries very close to 100% in the full range of cp. with knelson, the recovery is 100% for the 45250 microns tungsten at low cp values and drops dramatically when cp is increased. it is particularly important with the finer tungsten (038 microns). although the gangue is fluidized at cp values as low as 515 kpa depending on its particle size, operating at higher cp values yields higher grade concentrates because the gangue is elutriated. figure 2: comparison of the recovery, with the knelson and the falcon, of 45250m tungsten from a mixture with 74104m quartz. figure 3: comparison of the recovery, with the knelson and the falcon, or 3853m tungsten from a mixture with 147208m quartz. figure 4: comparison of the recovery, see full list on minerals.seprosystems by comparing similar experiments carried out on binary mixtures, it can be observed that the presence of a mineral of intermediate specific gravity does not modify the recovery of tungsten, both in the knelson and in the falcon. results for the knelson are shown in figure 7. however, the presence of ilmenite can modify the concentration ratio obtained and the working time of the gravity concentrators before cleaning, if according to their particle size, ilmenite particles are not fluidized in the working conditions. figure 7: effect of the presence and the particle size of ilmenite on the recovery with the knelson of the 4525m tungsten (147208m gangue). the falcon achieves almost 100% recovery for all tungsten

designed for the recovery of g. nevertheless, both can be used to concentrate materials lighter than g. for example, both concentrators can be used for the retreatment of tailings of base metals ores or for the beneficiation of wastes of small size. figure 8 shows the results obtained with a mixture of galena and quartz. galena shows a similar behaviour to the tungsten but the recovery is clearly lower in both concentrators. figure 8: influence of the water pressure on the recovery of the 3880m galena with the knelson and the falcon. see full list on minerals.seprosystems
