Derrick® G-Vault® technology outperforms wedge wire screens at OceanaGold’s Haile Gold Mine’s CIL circuit
The CIL circuit at OceanaGold’s Haile Gold Mine in South Carolina had a long history of wedge wire interstage screens plugging, wearing and leaking on a daily basis. These issues are due to a secondary feed stream being introduced to the circuit in addition to the first CIL tank’s discharge. This required the Haile Operations Team to pull and clean the screens daily. In late 2019, two Derrick G-Vault® screens were installed for a 12-week trial and were to be measured for performance, wear and durability.
As part of the trial, the G-Vaults operated in contest with the wedge wire screens in the first and last CIL tanks. This gave the Haile operation a unique opportunity to evaluate the screens side-by-side under typical operating conditions. This scope gave Haile a high level of confidence when evaluating the performance, wear and durability of the screens.
