ANDRITZ to deliver Advanced Process Control system for Ujina Concentrator copper deposit, Chile


ANDRITZ AUTOMATION, part of international technology Group ANDRITZ, has received an order from Compañia Minera Doña Ines de Collahuasi to supply an Advanced Process Control solution for the secondary grinding operations (including integration with the primary grinding process) at the Ujina Concentrator copper deposit in Iquique, Region de Tarapacá, Chile.

ANDRITZ will develop control applications for the classification process and product quality, including the supervisory level for the entire grinding circuit. The main goal is to improve the secondary grinding circuit by stabilizing the variables associated with the classification performance. This will be done by implementing ANDRITZ BrainWave, a patented model predictive controller, to stabilize the pressure and density of the grinding circuit while keeping the sump level within a safe range and by means of expert rules implemented in the ANDRITZ IDEAS simulation software. Finally, an expert layer will take over the whole grinding circuit with the objective of pushing the process to the production target while maintaining the product quality within a stable range.

Compañía Minera Doña Inés de Collahuasi SCM produces copper concentrate, copper cathodes, and molybdenum concentrate and operates the world’s third largest copper deposit.
