Gold Fields orders ABB integrated power and automation system for Salares Norte – International Mining

Posted by Paul Moore on 27th September 2021

ABB is to provide six electrical rooms plus an integrated digital system solution based on the ABB Ability 800xA distributed control system (DCS) to Gold Fields Salares Norte mining project in a remote region of northern Chile. The open-pit 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 1,300 km from the Chilean capital Santiago and has elevations between 4,200 m and 4,900 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, ABBs 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. ABBs 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 Ivn 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 ABBs control systems connect and perform their functions in totally isolated areas, within satellite range, and with minimal latency, said 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 1,300 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 Regional Secretary) 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 Moz of gold over an initial mine life of 11 years and is estimated to be a $834 million expenditure project. The operation involves drilling, blasting, loading, and hauling methods for ore extraction. It has a production capacity of two million tons per annum and the life-of-mine average recovery of gold and silver will be 92.7% and 67.5%, respectively.
