Steel Plant Wastes
During the manufacturing of steel, a significant amount of hazardous baghouse dust is produced that contains zinc and other metals and minerals generated from the steel smelting process. This dust is typically extracted by the air pollution control system on an Electric Arc Furnace (EAF). The traditional means of disposing of EAF dust is at a hazardous waste landfill site where the tonnage cost varies from country to country, but commonly, the costs continue to rise. Steel plant waste is difficult to recycle back through the primary steel plant facility due to environmental compliance issues and/or their physical form as particulates/dusts. The challenge is finding a solution capable to separating the valuable recyclable metals for either resale or reuse, from the hazardous waste.
How Tetronics can help unlock value from this process
Tetronics has extensive experience in the delivery of metal and mineral recovery plants specifically designed for the recovery of zinc, and other materials such as chromium and nickel from Steel plant EAF dust.
In Tetronics’ plasma‐enhanced material recovery technology, the process chemistry is designed to smelt and preferentially separate the valuable material and destroy the hazardous components, leaving the non‐hazardous material. The remaining non-valuable material is vitrified into an inert, safe disposable non‐hazardous material in a single processing step. A typical payback period of three years, or less, can be achieved by installing a Tetronics plant. The robust level of construction and minimal number of moving components delivers outstanding plant longevity. The recovery process also has exceptional environmental and commercial credentials and can be considered as a future‐proof solution to steel plant waste management problems.
