Each of Sino Iron's six milling lines consists of a primary autogenous (AG) mill and a secondary ball mill. Following three stages of magnetic separation and passing through the ball mill, the final high grade concentrate is produced. As the name suggests, magnetite ore is magnetic so we're able to use large magnetic separators to draw out the iron from the waste material. The

SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between
