In today’s era of energy transition and rapid development of the electronics industry, cobalt as a critical strategic metal, has become increasingly important. Cobalt sulfate, one of the key salt compound of cobalt, serves not only as a raw material…

Pickling is an essential process in the metal processing, electroplating, and steel industries. However, the resulting pickling wastewater, rich in hydrochloric acid and heavy metals, has long been a major environmental challenge and financial burden for companies. Traditional lime neutralization…

In many industrial fields such as chemical engineering, pharmaceuticals, environmental protection, and hydrometallurgy, it is often necessary to separate specific components from a liquid. In industry, this process is known as extraction. The efficiency of extraction directly determines the product’s…

With the rapid development of green energy and advanced manufacturing, vanadium—known as the “vitamin of modern industry”—is playing an increasingly critical strategic role in vanadium batteries, specialty steels, and the aerospace, etc. However, traditional vanadium extraction processes from vanadium shale,…

In the comprehensive development and utilization of high-magnesium brine resources, the extraction and removal of boric acid are critical steps for enhancing product value and purifying subsequent processes. However, challenges such as the high magnesium-to-boron ratio, low efficiency of traditional…

The generation of alcohol ether organic wastewater mainly occurs during the industrial production of isopropanol using the propylene hydration process in chemical plants. This type of wastewater contains large amounts of isopropyl ether and isopropanol. Isopropanol is a commonly used…
