The expansion of mining and RoM feed to the plant is particularly beneficial when the SAG-ball mill circuit is the bottleneck constraining production expansion The increased head grades to ball mill and downstream circuit (through waste rejection) can lead to increased metallurgical recoveries in flotation or conventional mill/CIP gold circuits

circuit, comprised of a 6.1 m diameter x 2.74 m long SAG mill and a 4.1 m diameter x 5.5 m long secondary ball mill in closed circuit with cyclones, was built using SAG Power Index and Bond Ball Mill Work Index testing to determine the grinding energy requirements.
The correct size material is sent to the ball mill for final grinding. Ball mill. The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. What is grinding circuit?What is grinding circuit?Grinding circuits are fed at a controlled rate from the …
approach the total speciﬁc energy of the entire AG/SAG circuit is ﬁrstly predicted using the SAG mill feed F80 and the ball mill cyclone overﬂow P80. Morrell’s model (Morrell, 2011) relates the feed, mill geometry and operating conditions to the speciﬁc energy of the circuit. However, the F80 is not enough to represent properly
Jan 01, 2009· "The comminution circuit at Barrick Cortez Gold Mine uses an open circuit primary jaw crusher followed by a standard SABC grinding circuit. The grinding circuit incorporates a 26’Ø x 11’ SAG mill, an Omnicone 1560 pebble crusher and a 16’Ø x 28½’ ball mill.
Zijin Mining Group has chosen an gyratory crusher, SAG mill and ball mill for the Majdanpek mine, part of the Chinese mining company’s majority owned Zijin Bor copper mine, in Serbia. The delivery of the equipment to Majdanpek, 180 km from Belgrade, is expected to occur between 12 and 18 months from now, with the project estimated to

Many circuit configurations are possible, but essentially the autogenous or SAG mill is operated as a single-stage primary mill, or it can be followed by secondary pebble or ball milling. The semi & autogenous mill is often operated in closed circuit with a trommel screen or external vibrating screen classifying the discharge.
Oct 10, 2016· SAG/ball (SAB) configurations represent the dominant comminution flow sheet within the company and the circuit configurations employed include SAB, SABC-A, SABC-B and single-stage (SS) SAG milling, with SAG mill feed ranging from run-of-mine (ROM) ore …
A possible circuit change would send the crusher discharge to the ball mill circuit, better balancing the work between the SAG and ball mill. When ball mill-limited and with low ore variability, a similar circuit modification redirecting flows can be done. It may be possible to redirect some of the ball mill hyrdocyclone coarse fraction back to ...
Chinese mining company Zijin Mining Group Company Limited has chosen FLSmidth to provide a gyratory crusher, SAG mill and ball mill to the Majdanpek mine, which forms part of their newly purchased Zijin Bor Copper mine group.
focused on the energy and cost comparisons of the existing AG/SAG ball mill circuits with two proposed comminution circuits, including an HPGR - ball mill circuit and a novel HPGR - stirred mill circuit. The main objective of this research was to advance the understanding of the potential
The second is the grinding circuit where ball fragments have resulted in wear to pumps and damage to pump impellers, as well as sumps, piping, hydrocyclones and liners. ... chips or scats in a typical ball or SAG mill operation. The trunnion magnet is mounted at the SAG ball mill discharge point and is used in place of a trommel screen ...
proposed flowsheet consists of existing SAG mill circuit followed by a new proposed ball mill in closed circuit with the existing hydrocyclone package In all simulations, SAGT, CYCL and MILL models were selected to simulate SAG mill, Hydrocyclone packages and ball mill units SAGT and MILL models both are based on the population balance model
