Experimental Data for Hydrochloric Acid Dissolution of Alumina from Nigerian Clay

Nigerian clay was used in an experiment to optimize alumina yield via acid dissolution. The study investigated five process variables using a central composite rotatable design and reported an optimum yield of 80.07%. The work was authored by Henry Oghenero Orugba of Delta State University.

Use Cases

• Modeling alumina yield based on calcination temperature, leaching temperature, acid concentration, liquid-solid ratio, and stirring speed.
• Training regression models for process optimization in hydrometallurgy based on the described experimental design.
• Benchmarking response surface methodology implementations against the reported correlation coefficient of 0.9209.
• Analyzing interactive effects of multiple process variables in acid leaching operations.

Strengths

• Reports a specific optimum alumina yield of 80.07%.
• Identifies five key process variables and their optimized values (e.g., calcination temperature of 677.27°C).
• Uses a defined statistical methodology (Response Surface Methodology based on a central composite rotatable design).

Limitations

• Row count and column-level documentation are unknown, which limits suitability assessment.
• The dataset's actual structure and availability for download are not described.
• Last update date is unknown; freshness is unverified.
