Ddetermination of bond work index of Bagega gold mineral deposit of Zamfara State, Nigeria

The study determined the bond work index of Begaga gold mineral deposit Zamfara State Nigeria using Berry and Bruce modified method. Sample was sourced random sampling Reference (Granite) known weight 15.13Kwh/ton ground for thirty minutes at a particular speed power consumed from rating ball mill. An identical Bagega whose to be in same mill under condition as that reference mineral. Size analysis performed. feed discharge both ores carried out 80% passing particle size two were estimated mathematically correlation approach. by equating indexes ore. It found approximately 14.24Kwh/ton which is within acceptable range 10 - 15.14Kwh/ton indicated literatures standard gold. This value means 14.25Kilowatts hour energy required reduced one tonne ore 1117.32μm 800.00μm, it should serve
