Customer Case Study of 140 mm Forged Grinding Balls at a Large Copper Mine

Tailored high-toughness φ140mm forged steel balls for large-scale SAG mill operation in SABC circuits — boosting throughput, lowering specific ball consumption, and cutting broken-ball failures, all without equipment modification.

Bottleneck in SAG Mill Throughput
High Grinding Media Consumption
Insufficient Impact Toughness

Specific solutions and verification indicators shall be determined based on ore properties, mill parameters, and on-site production targets.

Case Study of High Hardness & Low Wear at a Large Copper Mine

Client questions:Baseline Specific Consumption: 0.445 kg/t for 100 mm balls and 0.335 kg/t for 60 mm balls, resulting in high consumables costs.

Goldpro programme:① Goldpro supplied high-hardness forged grinding balls with surface hardness ≥60 HRC and volumetric hardness 59 HRC, tailored for hard grinding conditions; ② Complete data comparison against Russian-made grinding balls under identical mill, ore, and parameter conditions to establish the optimal make-up ball charging regime; ③ On-site technical tracking recorded net running hours, hourly throughput, power consumption, and grinding ball wear to generate standardized test reports.

Customer Case Study of 120 mm Forged Grinding Balls at a Large Gold Mine

Client questions:Mill No. 1: Baseline ball consumption of 0.41 kg/t, fluctuating grind fineness, unstable classification, and extensive manual ball replenishment.

Goldpro programme:①Coarse Grinding: No. 1 mill charged with customized 120 mm Goldpro forged grinding balls. ②Four-Stage Trial: Establish baseline performance →Adjust ball charge to operating conditions → Stabilize operation and collect data → Evaluate results and issue report. ③Continuous SCADA Monitoring: Track discharge particle size distribution, throughput, discharge density, circulating load, power consumption, ball charge, broken ball quantity, mill filling rate, liner condition, screen blockage rate, and full-size-range particle size distribution. Photograph and retain records of broken balls.

Application Case Study at CODELCO Group Ministro Hales Concentrator

Client questions:

Goldpro programme:① Supplied 350 tonnes/month of 140 mm (5.5") grinding balls for the SAG mill and 550 tonnes/month of 76.2 mm (3") grinding balls for the ball mills. ②Since Goldpro grinding balls were first used at Ministro Hales in 2024, Goldpro maintained a stable supply for 10 consecutive months, demonstrating product reliability and technical service capability through long-term on-site validation. ③ Provided wear-resistant grinding media solutions aligned with the requirements of green and smart mining operations.

CONFIDENTIAL PROJECTS

Confidential applications matched to your operating conditions

Some projects cannot be published. Share your ore, mill, current media consumption, breakage rate, and target KPIs so our team can identify a relevant reference.

Submit Conditions
HOW TO READ A CASE

Before reviewing the results of application cases, please check the following four factors.

Even for the same ore, mineral processing load and ore properties vary. Do not replicate the results without on-site verification.

Ore Properties

Compare hardness, abrasiveness, feed size and moisture content.

Operating Conditions

Check mill type, diameter, rotational speed, filling ratio and liner condition.

Control Methods

When comparing grinding products, keep ore, operation and testing conditions consistent.

Product Trial Period

It covers a sufficient wear cycle to distinguish long-term performance from short-term fluctuations.
