Gold Fields orders ABB integrated power and automation system for Chilean project

Global Mining Review,
Global technology leader ABB is to provide six electrical rooms plus an integrated digital system solution based on ABB AbilityTM 800xA distributed control system (DCS) to Gold Fields’ Salares Norte mining project in a remote region of northern Chile.
The opencast gold-silver mine project by the South African mining company is located in the Atacama Desert amongst the highest peaks of the Andes mountain range. It is 1300 km from the Chilean capital Santiago and has elevations between 4200 – 4900 m.
ABB will deliver a common platform for process and power control using ABB Ability System 800xA, Power and Process Control Library, and Camera Connect (the ABB video system embedded in the control platform for optimised process monitoring). ABB Ability Knowledge Manager will be used to manage information production through Plant Information Management System (PIMS), alongside ABB Ability Asset Vista Condition Monitoring (integrated with SAP), an extended operator workplace (EOW) as an integrated control room at the site, a collaboration table and 800xA Smart Client stations to enable read-only access to displays via a web browser.
As a common platform for the monitoring of productive, operation and support areas, ABB’s system will reduce technical risks and the number of interfaces to enable Gold Fields to unify processes at the highest level. The electrical system is fully integrated via the International Electrotechnical Commission (IEC) standard 61850, which ensures total control and visibility for the plant operations. ABB is also providing engineering and project management.
“The digital aspect is critical to this project due to its remote location – the nearest town being Diego de Almagro, 180 km away, the altitude of the project and adverse weather conditions which make site access and fieldwork difficult especially during the winter,” said Max Combes, Project Director of Gold Fields. “Gold Fields has developed digital infrastructure through initiatives at operations around the world. ABB’s complete solution, integrated engineering and remote operations technology will enable us to build on this digital capability and overcome the particular challenges at Salares Norte.”
The scope also includes a dynamic process simulator to allow checks on all control logics and for operator training purposes.
“The simulator will allow for shorter and more efficient start-ups on site,” said Iván Villegas, Solutions Manager at ABB in Chile. “It will also support the training requirements, meaning Gold Fields will have several accredited operators with the right skills for high-quality operations.”
“Together with Gold Fields, we can demonstrate over the long-term that ABB's control systems connect and perform their functions in totally isolated areas, within satellite range, and with minimal latency,” added Cristian Gallegos, Mining Account Manager for ABB in Chile. “It is an opportunity to modernise mining and showcase the benefits that digital transformation brings by controlling and supporting the mining plant and equipment at Salares Norte from 1300 km away.”
Satellite telematics test
In parallel to this project, ABB proposed and was part of an initiative together with Gold Fields to successfully connect different ABB technologies between Santiago and the Salares Norte project. Using satellite telematics, they carried out remote control and monitoring of smart electric motors and a simulation of telemedicine care between the two locations. The tests were carried out in isolated areas, but within reach of the satellite and through a connection controlled by ABB Ability System 800xA and conventional mobile equipment with minimal latency. Through mixed reality lenses, both virtual reality and augmented reality, two authorities of the Ministry of Mining in Chile (the Minister and the RegionalSecretary) each at one end, were witnesses and protagonists of the successful test, where the two held a conversation that flowed in real time, each ‘seeing’ the avatar of the other, as if they were together in a physical environment.
Salares Norte is expected to produce 3.7 million oz of gold over an initial mine life of 11 years and is estimated to be a US$834 million expenditure project. The operation involves drilling, blasting, loading, and hauling methods for ore extraction. It has a production capacity of 2 million tpy and the life-of-mine average recovery of gold and silver will be 92.7% and 67.5%, respectively.
