The development of the three-stage gravity recoverable gold test work and modelling, by the late André Laplante and the AMIRA P420 Gold Technology Group respectively, provided tools that have become the foundation of best practice design and operation of gravity gold circuits using batch centrifugal concentrators. Test work and modelling have enabled the design of predictable, low risk gravity gold circuits and facilitate continuous improvement.
Gekko Systems, in collaboration with Gold Fields Limited, were involved in the design of the Granny Smith and Gruyere gravity circuits in 2014 and 2015 respectively, and the design of the Agnew gravity circuit upgrade in 2012 and again in 2016. Gold Fields carried out mill and gravity surveys at each of the respective sites post-commissioning to establish baseline performance. Modelling of the survey data through the AMIRA P420 BCC Gravity Model generated recovery curves specific to the ore treated and the mill and gravity circuits being operated. This enabled both the variation in the recovery established during design, and opportunities to increase baseline recoveries to be verified.
Confirmed by surveying and modelling of the operating gravity circuits, the AMIRA P420 BCC Gravity Model was a robust tool in establishing the optimal gravity circuit configuration and capacity. In each case study, modelling of the operational gravity circuits indicated a mill discharge fed gravity circuit was the optimal configuration to maximise gravity recovery. This aligned with the outcomes from the design stage of modelling.
The gravity recovery estimates attained from the design modelling, however, did not reflect the gravity recoveries achieved in the plant. The design modelling of the Brownfields Granny Smith gravity circuit underestimated gravity recovery by 11 per cent. Design modelling of the greenfields Gruyere gravity circuit underestimated gravity recovery by 5.2 per cent. Remodelling of the GRG data applied during design with current mill operating data obtained from gravity circuit surveys identified that both the GRG data and the mill operating data can have a large influence on the position and shape of the modelled recovery curve. Given the accuracy of the model was validated repeatedly through modelling of surveyed data, where the Granny Smith, Agnew and Gruyere gravity circuit surveys resulted in a 3.2 per cent, 0.6 per cent and 1.0 per cent difference between the average plant gravity recovery and the modelled survey recovery, respectively, it was concluded that the gravity recovery discrepancies that exist between circuit design and real plant performance is a factor of the data that is applied during design.
This paper details the application of test work, modelling and performance monitoring of the Gold Fields greenfield, retrofitted and existing gravity gold circuits. The Gold Fields case studies compare the BCC Gravity Model predicted gold recoveries to those being achieved in plant operation. The paper highlights the capability of modelling in best practice gravity gold circuit design, and demonstrates its benefits, reliability and shortfalls.
The accepted ideology of the 1990s was that a cyclone underflow fed gravity circuit was the optimal configuration, because cyclones acted as pre-concentrators for gold in a milling circulating load (CL). Gravity circuits were commonly designed to be fed with one third of the cyclone underflow stream, as this was known to correspond to a plateau in gold recovery with gravity effort. The grain size of the gravity recovery gold (GRG) in the ore was rarely considered. Despite the benefits of the AMIRA BCC Gravity Model being available since 2005, the cyclone underflow fed gravity circuit arrangement as an optimal configuration is still a preconceived design concept amongst gold processing metallurgists today.
Gold Fields Australia (Gold Fields), in collaboration with Gekko Systems (Gekko), has been applying best practice gravity circuit design in the installation of new and upgraded gravity circuits since 2014. The upfront recovery of GRG at Granny Smith was reassessed in 2014 due to an increase in head grade overloading the downstream carbon-in-pulp (CIP) and elution circuit. In 2015, a gravity survey was carried out at the Agnew processing plant to identify opportunities to optimise the existing gravity circuit. The survey outcomes, in conjunction with the associated costs of maintaining the two superseded KC-CD30 Knelson concentrators, identified an opportunity to increase the gravity effort. An increase in recovery capacity would also manage the frequent occurrence of head grade spikes. An upgrade to two KC-QS40 Knelson concentrators occurred in 2018. In 2015 GRG testing and modelling was carried out as part of the design for the Gruyere gravity circuit. The Gruyere gold processing plant was commissioned by Gold Fields and ACJV in 2019.
This paper aims to prove the reliability of best practice gravity gold circuit design. It details the application of modelling in both greenfield and brownfield gold processing plants, and plants with existing gravity circuits. Through the Granny Smith, Agnew and Gruyere case studies, the paper discusses the gravity surveys and analyses carried out post commissioning to justify best practice gravity gold circuit design.
The first stage of any circuit design involves test work to quantify the target mineral, understand the mineralogy, and determine how the ore responds to the process in question. In gravity gold circuit design using a batch centrifugal concentrator (BCC), an ore sample undergoes three stage GRG testing. The three stage GRG test is an industry standard procedure developed at McGill University (Laplante, Woodcock and Huang, 2001) and simulates gravity recovery via a BCC in a milling CL at 100 per cent recovery efficiency. The test provides three stages of GRG liberation and recovery data and quantifies the GRG content of an ore sample. However, this test alone does not provide an estimate of the gold recoveries achievable on a plant scale; a concept that is still frequently misinterpreted. Modelling of the test work data using site specific milling and classification data simulates gold recoveries with gravity effort and provides a reliable estimate of the gold recoverable via a BCC on a plant. It is the outcomes from the modelling by which gravity circuit design is based.
The AMIRA P420 BCC Gravity Model simulates gravity circuit gold recoveries based on real milling circuit performance and is therefore a powerful tool for determining optimum circuit configuration and optimum gravity effort during the initial design process. The model, originally developed by André Laplante, became available online in 2005 to sponsors of the AMIRA P420 Gold Processing Technology Project and is maintained by the Curtin University Gold Technology Group (February 2020, personal communication).
The gravity recovery of sulfides in the tailings stream has been the primary focus of gravity gold recovery at Granny Smith. Ultrafine gold associated with sulfides is recovered via spiral concentrators, subjected to ultrafine grinding and fed back into the head of the leach circuit. The recovery of gravity gold within the milling circuit was re-evaluated at Granny Smith in 2014 due to an increase in head grade. With promising test work and modelling outcomes, a gravity circuit was retrofitted in the Granny Smith processing plant and commissioned in 2015.
