Electrowinning: costs and energy economics?

Electrowinning costs and energy economics

Electrowinning costs and energy economics are built up in this data-file. A charge of $900/ton is required to earn a 10% IRR on a $3,000/kTpa plant with a median energy…

Energy economics: an overview?

…the data-file, across our models of Air Separation, Cables, Comminution, Compressors, Electric Motors, Electrowinning, Fans, Flotation, Gas Dehydration, Harmonic Filters, Heat Exchangers, Inverters, Motor Drivers, Pumps, Rankine Engines, Tanks and…

Copper: the economics?

…e.g., via solvent extraction then electrowinning (the favored route for oxide ores that cannot be floated), can reduce total CO2 intensity by a further 1 tons/ton when using clean electricity….

Heap leaching: energy economics?

costs of heap leaching

…below). This leach solution is then accumulated for further processing, for example, by electrowinning. The typical costs of heap leaching with H2SO4 might contribute $2.5/kg to the costs of processing…

Bioleaching: case studies and examples?

Bioleaching case studies

…via electrowinning. The advantages of bioleaching are low costs and low CO2, as per broader heap leaching operations. The entire process likely costs $4,000-5,000/ton, which is approximately half the level…

Electrasteel: renewable steel breakthrough?

Electrasteel technology review

…ions from iron ores, electrochemically reduces Fe3+ to Fe2+, then purifies the Fe2+ ions, filters them to a separate electrowinning cell, and plates out pure Fe metal. This is patent…
