The ore will be crushed using four in-pit gyratory crushers before being transported to the concentrator. The crushed ore then enters the grinding circuit consisting of six grinding mill lines. Each line consists of a 12.2 m (40 ft) diameter × 11 m (36 ft) long AG mill with a 28 MW gearless motor in closed circuit with a pebble crusher and ...

crushed ore is transported mainly by a belt conveyor system and, more and more rarely, by truck to the pro-cessing plant. The competing option of autogenous and semiau-togenous grinding technology is the use of high-pres-sure grinding rolls (HPGRs). HPGRs are typically used in the third stage of crushing instead of fine

The Sadiola processing plant consists of twin circuits designed to treat 5.3mtpa of saprolite ore. The crushed ore from the SAG mill is carried to the leach circuit for leaching. The pulp is fed into the CIL plant where the carbon is stripped of the associated gold. The gold bearing solution is sent to the storage tanks.

Abstract. Crushed ore agglomeration has been used and is considered as a pretreatment step to improve heap leaching performance of complex copper and gold ores. It is well known that proper agglomeration can prevent solution channeling and ponding, improve percolation within the heap and increase metal recovery rates.
