Hydrometallurgy

In line with its comprehensive approach to cover all areas of engineering to add value to its clients’ projects, JRI established, in 2006, the area of Bio-Chemical Processes, which deals mainly with the study and design of hydrometallurgical processes. Since its inception, this area has participated in numerous projects, experimental designs, studies and assessments of heap leaching, solvent extraction and electrowinning plants, which has allowed it, along with the arrival of new and outstanding professionals, to accumulate relevant know-how in various areas of hydrometallurgy.

In hydrometallurgy, JRI has proven experience in the following areas:

• Agglomeration and piling
• Leaching oxidized and mixed ore
• Cyanidation
• Solvent extraction
• Electrowinning
• Effluent treatment
• Caustic materials and solutions handling
• Geometallurgical characterization of minerals
• Leaching of caliche
• Conceptual design for bioleaching
• Conceptual design for wastewater treatment
