Laterite processing is experiencing very rapid development through pyrometallurgy and hydrometallurgy. This development is also followed by the issue of green processing, so research on green laterite processing is more focused. In connection with related issues, this research is the beginning of the development of mineral processing with organic solutions, such as citric acid and monosodium glutamate, in hydrometallurgical processes from ferronickel processing by-products. Based on ICP, XRD, and SEM–EDS data, the use of organic solutions is very effective in mineral processing. Still, it needs development for organic acid solutions that dissolve almost all elements. In contrast, organic base solutions still require expansion to increase the recovery value, but this solution is more selective in reduction.

摘要

Laterite processing is experiencing very rapid development through pyrometallurgy and hydrometallurgy. This development is also followed by the issue of green processing, so research on green laterite processing is more focused. In connection with related issues, this research is the beginning of the development of mineral processing with organic solutions, such as citric acid and monosodium glutamate, in hydrometallurgical processes from ferronickel processing by-products. Based on ICP, XRD, and SEM–EDS data, the use of organic solutions is very effective in mineral processing. Still, it needs development for organic acid solutions that dissolve almost all elements. In contrast, organic base solutions still require expansion to increase the recovery value, but this solution is more selective in reduction.
