Burns Energy Systems has developed an improved process for the refining of zinc from dross prior to use for the production of zinc oxide and zinc dust. This integrated high yield process was jointly developed by A. H. Burns Energy Systems Ltd and zinc industry experts. The efficiency of the zinc recovery comes from the high efficiency of the melting and vaporizing furnaces, as well as the new optimized process.
The new Burns Energy Systems Tilting Melting Furnace has been designed to provide high metal solution temperatures and material mixing required to efficiently separate the iron prior to liquid charging of the vaporizing crucibles. Lead (if present in the dross) remains in the vaporizing crucibles and is periodically removed from the liquid zinc by liquation. Recovered lead can be re-sold to offset the processing costs.
Discharging 99.96% pure zinc recovered from dross.
