In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia []) owing to the exhaustion of rich copper resources.The flowsheet of processing copper ores is developed for each particular ore, but there are some …
PROCESS FLOWSHEET DEVELOPMENT FOR RECOVERING ANTIMONY FROM Sb-BEARING COPPER CONCENTRATES i Abstract Amid Europe's growing reliance on external antimony production, the European Commission has consistently emphasized an expanding supply-demand gap since 2014. Responding to this challenge,
The process flowsheet is an almost completely closed cycle and, in theory, only copper oxide and electrical power are required to produce ultrapure copper metal. The flowsheet is composed of three interconnected closed circuits: the leaching (solubilization of Cu), solvent extraction (up-concentration and purification of Cu solution), and ...
