12.14 Secondary Zinc Processing US EPA
2015-9-10 12.14 Secondary Zinc Processing 12.14.1 General1 The secondary zinc industry processes scrap metals for the recovery of zinc in the form of zinc slabs, zinc oxide, or zinc dust. There are currently 10 secondary zinc recovery plants operating in the U. S., with an aggregate capacity of approximately 60 megagrams (60 tons) per year.

2018-9-12 There are large quantities of waste materials generated by the high scale industrial activity and communal consumption. These materials can be considered as valuable secondary resources of metals. On the other hand, they also represent environmental or health hazards. Therefore, processing, with the general aim of extracting the metallic values, is more and more often indispensable. As the primary resources of zinc are becoming rather scanty and zinc consumption is dynamically increasing especially by the scale of zinc coating is applied to steel products, zinc containing secondary

A brief overview of secondary zinc anode
In the state of the art, the information about secondary zinc anode for rechargeable zinc‐air batteries is scarce. The main development of the technology has been lately concentrated on the bifunctional air electrodes while the used zinc anode is mainly based on a planar zinc electrode providing low specific energy densities for the full system.

Secondary Zinc Processing. Secondary zinc production uses process scrap from zinc slabs, zinc oxides and zinc dust. Selective melting may also be used to capture zinc if the zinc is mixed with other non-ferrous metals with higher melting points. Zinc is also often recovered from the furnace dust of galvanized steel making plants.
