Metal separation and purification

For hydrometallurgical recycling of battery and refining of Nickel-cobalt hydroxide precipitate (MHP), Botree not only provides the traditional step-by-step impurity removal and extraction process carried out by P204 and P507, but also develops novel ultra short BC196, BC211 and other extraction systems. In traditional process, impurities like Ca, Mg should be removed first and Mn, Co, Ni should be extracted separately. However, in Botree new extraction system, Ni, Co, Mn can be selectively co-extracted while impurities Ca, Mg are left behind.

co-extraction system (BC196, BC211, etc.)

Synchronous extraction of Ni, Co, and Mn, directly producing battery-grade materials, especially suitable for high-nickel systems

Over 30% reduction in extraction equipment investment, over 10% reduction in extraction energy consumption, 5-20% reduction in extraction costs

Compared with traditional processes, the carbon footprint of the full hydrometallurgical process is reduced by 6-8%^[1]
