and performance. The mill will be operated as a single stage SAG mill (primary and secondary duty combined). The extremely high throughput is facilitated by incorporating the use of Outotec''s patented Turbo Pulp Lifter (TPL™) technology. The grinding mill will be installed during 2014 at First Quantum''s Kansanshi Copper Mine in Zambia.
SAG/ball (SAB) configurations represent the dominant comminution flow sheet within the company and the circuit configurations employed include SAB, SABCA, SABCB and singlestage (SS) SAG milling, with SAG mill feed ranging from runofmine (ROM) ore through to secondary crusher product.
in the SAG mill circuit if no crusher was present. The ball mill, the final grind stage, is closed with a hydrocyclone classifier that removes undersized material and sends it to the separation stage. At the beginning of 1980s, the De Xing copper mine was the first to employ a SABC circuit in China.

The Phoenix Mine was charged with the goal of establishing an effective secondary crushing circuit to reduce feed size, hopefully resulting in an increase in SAG mill capacity. Originally, all pitrun material was processed through a gyratory crusher which fed a stockpile preceding the SAG mill.
SAG is an acronym for semiautogenous grinding. 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'' () in diameter, powered by a 28 MW (38,000 HP) motor.
