“…Panned sample was International Journal of Nonferrous Metallurgy adequately mixed after washing to achieve homogeneity [7]. Dried sample was crushed using Pascal Engineering crushing mill with machine number 18,862 operated at 415 V, 2200 W, 4.9 A and 50 Hz [8]. A working sample size of 500 g obtained using random sampling method followed by cone and quartering sampling method was pulverised using a pulverizer and sieved through 300 µm and 75 µm sieve sizes [9].…”

The response of Imogbara (Nigeria) gold ore to shaking tabling gravity separation methods was investigated in this research work. Gold concentration in run-off mines is usually as low as 0.005 ppm and must be upgraded in order to reduce the recovery process extraction costs. Gravity separation method (the focus of this work) is one of the readily affordable beneficiation methods. Shaking table is a developed separation equipment of gravity method that has been adopted to increase concentrate based on difference of specific gravity. The output result of the concentration process using shaking table is basically influenced by a number of variables, such as rotational shaking speed, particle size and deck slope. In this research, the range of rotational speed shaking was between 100 rpm and 200 rpm, the particle size was between (−300 µm > X < +75 µm) and (−75 µm) and deck slope was between 10˚ and 30˚. EDXRF was used to measure gold concentration in the concentrate as well as the tailings. The result shows that the optimum condition is obtained at a shaking speed of 100 rpm, with a slope of 10˚ and particle size less than 75 µm.
