A 13′ x 6′ sag mill has a reasonable range of: 20 to 30 tph for gold ore sag & ball mill duty; 25 to 40 t/h for copper porphyry sag & ball mill duty; in single stage sag duty, the approximate capacity reduces to only 8 to 13 tph for gold ore duty.The autogenous mill itself is a coarse-grinding device, consisting of tumbling drum with a 25% .
Characterized by a large diameter and short length sag mills are primarily used for grinding gold, platinum, copper, lead, zinc and silver.Hammer mills, unlike ball and rod mills, act to shred mining ore rather than grind it.A hammer mill consists of a steel drum with a vertical or horizontal rotating shaft on which hammers are mounted.
Following implementation of these strategies, the sag mill throughput when treating the harder copper/zinc ores increased from 2,750 tph to an average of 3,600 tph, and the optimization of the overall process improved energy efficiency, resulting in considerably less energy consumption per ton of product.

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.Get price; sag mill copper sag millbuy mill sag mill granding mi.
Smelters typically pay 95% (au) and 90% (ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of pb/zn smelter integration) for gold and silver in zinc concentrates.Cost drivers are also important in flowsheet selection, and are summarised in table 3.
The copper mountain mill flowsheet is currently a conventional two-stage crushing, semiautogenous grinding (sag) mill, pebble crusher, ball milling, and sulphide flotation circuit design.
The most cost-effective of these derived strategies were analyzed by a joint antamina and metso team and implemented on site.Following implementation of these strategies, sag mill throughput when treating the harder copper/zinc ores increased from a target of 2,750 mt/h in 2007 to 4,000 mt/h in 2009 and 4,400 mt/h in 2010-11.
