In hydrometallurgy, electroplating, titanium dioxide production, and petrochemical refining industries, large volumes of waste sulfuric acid with low concentration and high impurity content are generated. If such waste acid is directly disposed of, it not only incurs high hazardous waste…

With the rapid development of the electronics industry, the demand for printed circuit boards (PCBs) continues to rise, and China has become the world’s largest PCB manufacturing base. Statistics show that about 20% of the annual industrial copper consumption in…

In the fields of fragrances, pharmaceuticals (especially penicillin G), and agrochemicals, phenylacetic acid serves as an indispensable key intermediate. Its purification and recovery processes directly affect the quality of the final product, overall production costs, and enterprise efficiency. Traditional extraction…

With the global depletion of sulfide nickel resources, laterite nickel ore has become the main focus for future nickel resource development. However, traditional hydrometallurgical processes face major challenges such as long processing routes, low recovery rates, and difficulties in impurity…

In the field of rare metal metallurgy and advanced material preparation, the separation and extraction of rubidium and cesium has long been recognized as a technical challenge. Traditional methods such as mixer-settler extraction, ion exchange, or precipitation not only involve…

H-acid is an important intermediate in the dye industry. The wastewater generated during its production process is extremely complex and has the following characteristics: Direct biochemical treatment of this type of wastewater is largely ineffective, while advanced oxidation processes or…
