Zhisheng alumina process prediction at Guangxi Huasheng

Guangxi Huasheng put its Zhisheng alumina model into production and reported 88% accuracy for an evaporation indicator

WorkingCompany's own claimOfficial ↗

Problem

Operators relied on experience and delayed laboratory results to manage alumina production.

Approach

Guangxi Huasheng developed Zhisheng Alumina using Chinalco's Kunan model. It completed pilots and put predictions into use in dissolution, settling and evaporation.

Results

88%prediction accuracy for sixth-effect evaporation NK in the first half of 2025, per ChinalcoCompany's own claim[1]

85%prediction accuracy for dissolution AK in the first half of 2025, per ChinalcoCompany's own claim[1]

80%prediction accuracy for settling NT in the first half of 2025, per ChinalcoCompany's own claim[1]

Takeaway

Prediction accuracy varied by process indicator, from 80% to 88%; the figures did not measure finished-product quality.
