Good recovery of spiral concentrator

May 01 2012 Also the relationship between the predicted and observed value of the responses is shown in Fig 5 which shows that the fit is quite good as the R 2 value for grade and recovery of the concentrate fraction of the spiral concentrator is 094 and 093 respectively The standard deviations of both the predicted models are 25 and 33 for grade

Product Introduction

Spiral Concentrator Circuit Circulating Load Gravity

This all depends on the mass coming from Underflow density etc the way described I have seen most spirals I have worked with are good for 3 TPH stated on each spiral flightwith most metals and more with coal They say they are good for a 40 density but this is trouble from what I have seen If you know your mass is within reason it will work

Recovery on a spiral has been shown to increase with an increase in solids concentration up to a point where it is optimum and then drops at relatively high solid concentration Richards amp Palmer 1997 When separation is in progress on the spiral the heavy particles migrate toward the inner region

Spiral concentrators are capable of sustained recoveries of heavy minerals in the size range of 3 mm down to 75 microns 6 to 200 mesh They are suitable for use as roughers cleaners or scavengers Feed rates may vary from 05 to 4 tons per hour per start depending on the size shape and density of the valuable material

Gold Spiral Wheel Concentrators provide Excellent Fine Gold Recovery from Black Sand concentrates Spiral Wheel Gold Concentrators make panning automatic they can recover all sizes of gold from micron and flour gold to coarse nuggets Some models like the Gold Magic can even work Wet AND Dry

Spiral Concentrator Metso Outotec

Heavy minerals such as ilmenite or hematite settle out rapidly in a spiral concentrator and they should be removed as soon as a good wide band forms Since the concentrate band is wider at the top splitters near the top of the spiral concentrator should be opened wider than those near the bottom

May 01 2012 Also the relationship between the predicted and observed value of the responses is shown in Fig 5 which shows that the fit is quite good as the R 2 value for grade and recovery of the concentrate fraction of the spiral concentrator is 094 and 093 respectively The standard deviations of both the predicted models are 25 and 33 for grade and recovery respectively which are acceptable

New spiral means better recoveries for ferrochrome and beyond Following years of detailed test work in the ferrochrome sector Multotec has successfully developed and proven a spiral concentrator that eliminates beaching and enhances recoveries in the 1 mm to 3 mm fractions of highdensity material Significantly when compared to

MGS improves the metallurgical recovery and quality of concentrate for graphite carbonbearing sulfide ore and high aluminabearing fine iron ore MGS technique is working successfully at RajpuraDariba zinclead plant and all iron ore plant in India by decreasing graphitic carbon and alumina respectively

Gold centrifugal concentrator is useful in the gold recovery in all ranges of particle size It is most especially useful for recovering fine gold which gets lost during the operation of gravity concentrators The application has shown that the recovery of gold can be very high as much as 99 and the concentration ratio is up to 1000 times

Oct 01 2017 Fig 4 shows the recovery at various zcoordinates according to the grades For the 90 grade the recovery increased extremely fast at the initial stage and reached 80 after it flowed 05 m downward from the top Below this point the recovery increased gradually and reached the limit of 92 at the point of z 05 m For the 95

PDF Case study High capacity spiral concentrators

Spiral Concentrators Spiral concentrators are modern high capacity low cost units developed for the concentration of low grade ores Spirals consist of a single or double helical sluice wrapped around a central support with a wash water channel and a series of concentrate takeoff ports placed at regular intervals along the spiral To increase the amount of material that can

R2 is quite good as R2 values for grade and recovery of the concentrate fraction of spiral concentrator are 094 and 093 respectively The high value of R2 indicates that the quadratic equations are capable of representing the system under the given experimental domain

Modeling and optimization of spiral concentrator for

Predicted values of responses obtained using model equations were in good agreement with the experimental values The influence of the process variables of the spiral concentrator on grade and recovery of concentrate fraction was presented and discussed Graphical abstract

May 01 2012 Also the relationship between the predicted and observed value of the responses is shown in Fig 5 which shows that the fit is quite good as the R 2 value for grade and recovery of the concentrate fraction of the spiral concentrator is 094 and 093 respectively The standard deviations of both the predicted models are 25 and 33 for grade
