  • Jig concentrators Wikipedia

    Jig concentrators Wikipedia

    Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density).Fote Mining Machinery Co.. The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed.There are many variations in design; however the basic principles are constant: The particles are ... read more

  • Beneficiation of Fine Coal Using the Air Table

    Beneficiation of Fine Coal Using the Air Table

    Air table and air jigs were used to clean the coal. However, by 1985 the coal processing using these methods dramatically dropped to less than 7 million tons per year [5]. An excellent review on earlier dry cleaning processes is given by Symonds [6] and Donnelly [3]. In a pneumatic jig separator stratification is achieved through pulsating air and an oscillating deck. The average capacity for an air jig is 100 tph, … read more
