Dec 1, 2011 In December 2008, Siemens started up the world's first oregrinding mill with the frozen charge shaker function at the Rio Parau gold mine. With the help of this solution, which is integrated in the SimineCIS Mill GD gearless mill drive, charge that has become "frozen" to the mill's inside shell can be

Major Mines & Projects Parau Mine Mining Industry Data

In Plant I, ore is crushed through two stages and ground in ball mills prior to gold recovery by jigs and flotation. The concentrate is treated by gravimetric methods first and the coarser gold is recovered. The flotation and gravity concentrate is then leached with cyanide in a carboninleach (CIL) circuit, followed by carbon

Kinross: Operation: Parau Brazil

Parau's Plant II expansion commenced production in 2008 with the addition of a new 32 million tonne per annum (Mt/a) SAG mill. Further Plant II expansions were carried out to increase grinding capacity and recovery, including installation of a third ball mill and flash flotation. An increase in processing capacity was

development and operation of a water balance at rio parau

Mar 30, 2006 Ball mills are in closed circuit with hydrocyclones. A portion of the circulating load passes through jigs for gravimetric recovery of gold (Fig. 3). Flotation is conducted in three stages: flash, scavenger and cleaner for Au and sulfide recovery. The floatation tails are thickened and then sent to the main tailings

an existing SABC (SAG mill with recycle crushing and a single stage ball mill). First, a precrush stage using HPGR was introduced to minimise the generation of critical size material in the primary mill. The aim was to reduce a portion of the feed material below critical size and generate more fines to decrease the load in.
