La Oroya (Electrolytic) zinc smelter
*Please note that this report only includes an Excel data file if this is indicated in "What's included" below
Report summary
The La Oroya smelter in Peru uses roast, leach, electrowin technology to produce slab zinc. After floatation to produce a zinc-silver concentrate, around 40% of the leach residues are treated in a Waelz kiln to enhance zinc recovery and to provide a fume feed to the indium plant, the remainder being dumped. The current capacity of the smelter is 43kt/a of slab zinc. The long term future of the smelter is currently in doubt due to a huge debt burden and ongoing environmental issues.
