Industries such as steel galvanizing are very dependent on processes like pickling. Pickling is a technique to remove scale and oxides from metal surfaces using strong acids. This technique is crucial, but on the other hand, it produces a significant byproduct – spent pickling liquor, rich in dissolved metals such as zinc and acids, including sulfuric or hydrochloric acid. Conventionally known as waste, this byproduct is now being viewed from a different perspective; however, with the rise of acid treatment solutions and metal recovery systems , which promote sustainability, regulatory compliance, and cost-efficiency. Understanding pickling liquor – the hidden resource Particularly from galvanizing lines within U.S. steel plants, pickling liquor contains valuable elements. Over time, these acids become saturated with metal ions, particularly zinc, rendering it ineffective for future use and transforming it into a waste stream. Conventionally, this liquor was neutralized and disp...

The demand for sustainable and cleaner industrial processes is consistently growing. Hence, steel manufacturers are adopting innovative methods to reduce waste and optimize resource utilization. One vital area introducing tremendous technological evolution is acid recycling, particularly in processes like pickling stainless steel . Recycling acid not only minimizes environmental impact but also remarkably lowers operational costs, making it an integral part of modern steel plant operations. In this blog, we will discuss cutting-edge acid recycling techniques , their role in steel manufacturing, and how techniques such as solid separation systems play an essential role in driving this transformation. Why acid recycling matters in steel manufacturing The use of acid pickling is widely acknowledged for cleaning and descaling stainless-steel surfaces in steel manufacturing. It includes immersing steel in acid baths (usually nitric, sulfuric, or hydrochloric acid) to remove impurities and...
