zinc is subsequently electrowon
using conventional technology.
56 percent interest in Cerro Verde, an open-pit mine producing both electrowon
copper cathodes and copper and molybdenum concentrates.
The expanded plant will produce 124M lb/yr electrowon
cathode at a cash cost under $0.
In late 1997, Codelco brought on stream the first, US$640 million-plus, phase of the Radomiro Tomic project came on stream with an initial design capacity of 150,000 t/y of electrowon
high-purity cathodes (this issue, p.
FCX owns a 51 percent interest in El Abra, an open-pit mine producing electrowon
Besides, 441K st were electrowon
from primary sources.
New lead anode alloys, cobalt electrolyte additions and the high grade feed from SX plants are producing modern electrowon
cathodes equal to or better than high grade electro-refined copper.
Copper is electrowon
as dendrites on dimpled cathodes in diaphragm cells, then briquetted or converted to wire.
copper's contribution to production continues to rise, and investment in larger haul trucks should cut costs further.
cathodes are shipped directly to the rod plant.
cathodes will be smelted to dore bars for shipment.
Phase 2, which consists of the new $200M ammonia leach plant to convert a percentage of the concentrates into the purest electrowon
cathodes in the world, was officially inaugurated on Jan.
