Determination of work index of Filin Kokuwa Gold Deposit in Toro Local Government, Bauchi State Nigeria

Abstract


 
 
 This report shows the work index of Filin Kokuwa Gold ore sample in Bauchi State, Nigeria. The “reference sample (granites)” were sourced from outcrops of granites around Toro town. The samples were crushed, ground, and pulverized using appropriate laboratory milling machine. 80% passing size for the gold ore and granites samples were obtained at 100μm sieve size for the ball mill feeds and products respectively. The work indexes of reference samples i.e. granites were used to calculate the work index of the Filin Kokuwa gold ore sample. The values of 13.277kWh/ton and 15.192kWh/ton were obtained respectively for the two different reference granites samples used and 14.21kWh/ton as their average which is the value of the work index of the Filin Kokuwa gold ore deposit. The energy required for grinding the ore was found to be 3.581kW.
 
 

Exploration and characterization of barite mineral from azara-nassarawa ore deposits for suitability in industrial applications

“…More so, 125 and 90 µm had 33.7 and 16.4% passing through, respectively, and about 4.8 % passed through the 50 µm sieve and was retained on the base pan. In addition, the particle size with 60% and 80% passing was determined, adopting 'Gaudin Schumann' mathematical relationship in Equations 3 to 5 (Bwala et al, 2021).…”
