Study of Copper and Zinc Extraction from Underspoil

2020-3-1  An integrated flow diagram of water processing to extract copper (27–28% Cu) and zinc (49–51% Zn) concentrates has been developed. The extraction of copper and zinc was 94–95% and 99%, respectively. The quality of copper and zinc concentrates meets the requirements of GOST R 52998-2008 and GOST R 54922-2012, respectively.

Study of Copper and Zinc Extraction from Underspoil

The subject of study was the Safyanovskaya Med company’s acidic underspoil water containing 0.17 g/liter of copper and 1.8 g/liter of zinc (pH 2.8–2.9). The goal was to study and develop a technology of cleaning water of impurities (copper, zinc, aluminum, iron, manganese), accompanied by extraction of copper and zinc in the form of commercial products.

Copper reducing fresh water use in the production of

2014-3-30  For processing of copper sulphide concentrates through smelting, water is required for cooling and washing of smelter gases as well as in the acid plant. Similar to concentrators, water usage can vary between operations. A report commissioned by the Chilean Copper Commission (Cochilco) in 2008 [Brantes Olivares, 2008] lists the average fresh water consumption for a smelter as 3.6 m3/t concentrate processed. Using Codelco’s Ventanas smelter as an example, a fresh water value of 3.1 m3/t concentrate can be calculated based on numbers reported by the company in their 2011 sustainability report. Another source [Norgate Lovel, 2006] quotes smelter water consumption of 7.8 m3/t copper cathode for Boliden’s Ronnskar operation. Referring to Ronnskar’s more recent sustainability report from 2012, a value of 8.2 m3 fresh water/t copper

On-line Solid Phase Extraction of Copper in Water

An on-line solid phase extraction method for the preconcentration and determination of Cu(II) by flame atomic absorption spectrometry has been described. The procedure is based on the retention of Cu(II) ions at pH 6.0 on a minicolumn packed with Amberlite XAD-1180 resin impregnated with chrome azurol S. After preconcentration, Cu(II) ions adsorbed on the impregnated resin were eluted by 1 mol ...
