Faena: Antucoya Mine
Deadline 03/04/2023
Closing Time 4:00 pm
Minera Antucoya’s Dry Area, which has 2 primary crushers, 3 secondary crushers, 12 tertiary crushers and an agglomeration area, currently processes 32 million tons per year with grades of 0.35 % CuT. These high treatment levels allow meeting the fine copper requirements, but represent a stress condition for the crushing plant facilities, where any leakage or spillage, added to low ore humidity (0.7%), climatic conditions (wind) and design features (open buildings, ore transfers at height, among others), cause particulate matter emissions that are difficult to control and mitigate with the current dust suppression systems.
The objective of this challenge is to identify technological solutions to avoid and/or mitigate fine particulate matter emissions at different points and equipment of the crushing plant, such as crushers, screeners, chutes and material transfers between conveyor belts.
