In the field of platinum group metal metallurgy, solvent extraction has become a key technology for the efficient separation and enrichment of platinum group metals due to its unique advantages, and has also brought broad development opportunities to extraction equipment manufacturers.

Solvent extraction involves a rigorous process, encompassing key steps such as extraction, washing, stripping, and regeneration. During extraction, a specific extractant precisely reacts with the target metal ion to form an extractant that enters the organic phase. For example, sulfide extractants can highly selectively extract PdCl₄²⁻. Washing effectively removes impurities from the organic phase; stripping returns the metal from the organic phase to the aqueous phase; and regeneration restores the organic phase's extraction performance. This series of processes places extremely high demands on equipment performance.

Among its advantages, solvent extraction offers remarkable selectivity. By tailoring the extractant's molecular structure, it can achieve highly efficient separation of specific metals. Hydroxime extractants, for example, exhibit high selectivity for palladium. Its operational flexibility is also a major drawback, allowing optimization of extraction efficiency through adjustments to parameters such as solution pH, extractant concentration, and temperature. Furthermore, this method offers low energy consumption and minimal pollution, aligning with the trend toward green metallurgy.

As an extraction equipment manufacturer, we are fully aware of our significant responsibility.
