Today, as scattered metal resources are receiving increasing global attention, indium, as a key raw material for photovoltaic thin-film materials, high-end display panels, and semiconductor devices, plays a critical role in the stability of downstream industries. The stability of its…

Dihydroxybenzene has three isomers: catechol, resorcinol, and hydroquinone. They are widely used in pharmaceutical intermediates, pesticide synthesis, rubber antioxidants, dyes, photographic materials, and other fields. Due to the extremely similar physicochemical properties and close boiling points of these three isomers,…

During the production of active pharmaceutical ingredients (APIs), solvent extraction has always been a critical step that determines product yield, purity, and manufacturing cost. Traditional extraction columns and mixer-settlers have dominated the industry for decades. However, as the global pharmaceutical…

In the highly competitive non-ferrous metal smelting industry, solution purification and target metal enrichment technologies directly determine the market premium capability of final products. Facing the dual pressures of declining global resource grades and increasingly stringent environmental regulations, traditional gravity…

In the organic acid industry, lactic acid, as one of the three major organic acids in the world, is widely used in brewing, pharmaceuticals, food, leather processing, and many other fields. At present, the fermentation process for lactic acid production…

With the rapid growth of global electric vehicle ownership, the disposal and recycling of spent lithium-ion batteries have become a key issue in the fields of resource recycling and environmental protection. In the hydrometallurgical process, the solvent extraction stage directly…
