2% and silver recovery had lifted 40% after it licensed its Elution and Electro-Winning
circuit at its New Luika pit.
These stockpiles will provide the feed for the Stage 2 solvent-extraction and electro-winning
(SXEW) plant for the first three years of operations.
a Carbon in Leach process followed by electro-winning
and smelting to
The study evaluated an open-pit, heap leach, solvent extraction, electro-winning
project capable of producing 17 000 tonnes per annum of copper with a 11-year mine life.
The T'Boli Project is now fully equipped, including a trained local workforce, a fully constructed and commissioned Carbon-In-Leach (CIL) gold-silver processing plant, gravity concentrator, electro-winning
circuit, tailings storage facility and powerhouse.
The heap leaching process facilities and equipment necessary to initially capture the gold in solution as well the equipment used in subsequent stages of gold recovery including carbon columns, pumps, stripping circuits, electro-winning
circuits and furnaces is being solicited.
A preliminary economic analysis will be undertaken to ascertain the viability of leaching and electro-winning
Domestically, the copper scrap market suffered in the late 20th century as domestic copper smelters and electro-winning
refineries were the subject of great scrutiny by the United States EPA.
When Avmin bought the Chambishi plant it comprised a roaster, leaching vessels, copper electro-winning
and an acid plant.
The solutions were clarified and then subjected to zinc precipitation and/or electro-winning
for gold recovery.
As Tiger concluded the building and commissioning of its Phase II solvent extraction electro-winning
(SXEW) plant at Kipoi - within record time, it launched cathode production on 25 May 2014.
