APPLICATION CASE
Application Case Study at CODELCO Group Ministro Hales Concentrator
Goldpro grinding media entered the Ministro Hales Concentrator under CODELCO (Chile), the world's largest copper producer. Equipped with 140mm steel balls for SAG milling and 76.2 mm steel balls for ball milling, 10 months of continuous, stable supply earned the client's "Major Contributor Supplier for Grinding Media" certification, empowering green and smart mining operations.
Grinding stage1 × 36' × 19' (10.97 × 5.79 m) SAG mill using 140 mm grinding balls; 2 × 22' × 36' (6.71 × 10.97 m) ball mills using 76.2 mm grinding balls.
Primary objectivesSupply dual-size grinding media for SAG + ball mill grinding circuits at DMH Concentrator · Pass long-term on-site verification with reliable quality and service · Support efficient, sustainable operation of green smart mines.
Validation methodOn-site Continuous-use Validation: Entered Ministro Hales in 2024 and, after 10 months of stable supply and use, earned the client's "Major Contributor Supplier for Grinding Media" certification.
