PRIMARY CRUSHING RunofMine ore is delivered to a 60 x 89 gyratory crusher by 240 ton reardump trucks. The primary crusher operates under nominal closed side setting of 152.4 mm which results in a P80 of approximately 152 mm. Crushed ore is conveyed to a conical stockpile before the secondary crusher by a conveyor belt operating at a
