A Cat 7495 electric rope shovel originally built in 2012 is on its way to Kinross Gold’s Paracatu gold mine in Minas Gerais, Brazil.
Paracatu, an open-pit mine with ore processed in ball and SAG mills, is Brazil’s largest gold mine, according to Kinross. It achieved record annual production of 619,563 gold-equivalent ounces in 2019, surpassing its 2018 record.
Kinross started an asset optimisation program in 2018, which completed in late 2019 with the successful implementation of a grade control program that led to better characterisation of the orebody, an improved ability to predict and react to ore variability, and better mill efficiency with improvements in throughput and recovery, it said.
Cat said the shovel’s ballast box and revolving frame left Green Valley, Arizona, USA, last week on two heavy haul trucks – one pulling and one pushing the 120 t load. At 61 m long and 5 m wide, the load is being escorted by a team responsible for removing and replacing power lines, traffic signals and signage along the way, it said.
Late last year, Cat updated the AC electric drive system for Cat 7495 and 7495 HF electric rope shovels to, it said, deliver even greater reliability, improved maintenance access, enhanced safety and an expanded ability to perform at high altitudes and in extreme temperatures.
Back in 2018, Kinross welcomed its second Cat 7495 electric rope shovel to its Round Mountain mine, in Nevada, as part of its Phase W expansion plan.
