FIRST YEAR OF OPERATION OF HPGR AT TROPICANA

2020-3-17  Pilot plant scale test work summary and HPGR size selection is compared with actual operation results. In summary, the HPGR reached full operational capability within days of commissioning. This operational availability of the HPGR contributed to a quick ramp up of the entire plant that was achieved within weeks of commissioning. By February 2015

RAPID RAMP-UP OF THE TROPICANA HPGR CIRCUIT

2014-10-1  The 5.5 Mtpa Tropicana Gold Project in Western Australia adopted a HPGR ball mill comminution circuit due to the high cost of power generation and to reduce its energy footprint in line with its environmental operating licence. In order to maximise the benefit from the HPGR, closed circuit operation with wet screening at 4 mm was selected.

Operations Tropicana Joint Venture

Late in 2018 a second ball mill was added to the Tropicana processing plant increasing throughput capacity to more than 8 Mtpa, and providing flexibility to balance throughput and recovery. The modern processing plant uses conventional carbon-in-leach technology and includes high pressure grinding rolls (HPGR) for energy-efficient comminution.

2019-6-5  The HPGR operates in closed circuit with wet screens. The design includes the ability to continuously divert a fraction from the HPGR discharge to create a HPGR fines emergency stockpile. This stockpile is then reclaimed using a front-end loader to feed the wet screens when the HPGR or secondary crushing plant is off-line.

The result was that the HPGR–ball milling circuit remained the preferred option for the Tropicana project. The laboratory HPGR test work was completed by Polysius on a pilot scale HPGR with a 500 mm diameter and 300 mm width.

In the last quarter of 2016, a Caterpillar 6060, 600-tonne class shovel was introduced to the open pit mining fleet at Tropicana to increase mining rates to an annualised rate of 80 Mtpa and to better match the higher throughput requirements of the processing plant.
