LEACHING OF LOW-GRADE COPPER ORES: A CASE STUDY FOR

The copper concentration in the leach solution ranged from 0.80 to 1.75 g dm-3. The total Cu recovery rate ranged from 30 to 56 %, whereas the recovery rate of copper oxide minerals ranged from 67 to 100 %. Furthermore, with increasing the amount of liquid phase, copper recovery increases as well, and copper oxide minerals were completely leached out. Besides copper ions, considerably high

Copper Mining and Extraction: Oxide Ores

The pregnant leach pond contains copper ions that give it the blue colour of copper sulfate. The liquid is continually pumped to the SX-EW plant. 3. Copper sulfate solution is collected in the pregnant leach pond then pumped to the solvent extraction plant. The solvent extraction phase of treatment occurs in two stages. During the initial phase an organic solvent is used to recover copper ions

How Hydrometallurgy and the SX/EW Process

The process involves leaching the material with a weak acid solution. This solution, known as pregnant liquor, is recovered and then contacted with an organic solvent, referred to as the extractant, in the solvent extraction stage (SX). Here the copper is extracted away from the aqueous phase leaving behind most of the impurities that were in the leach solution. Since the copper ion is

Florence Copper Project, Pinal County, Arizona,

It will dissolve the copper ore to produce a copper laden pregnant leach solution (PLS). The recovery wells will collect the pregnant leach solution and pump it back to the surface where it is further processed via solvent extraction and electrowinning (SX/EW). The SX/EW plant will remove copper from the PLS and the remaining raffinate solution will be recirculated to the well field. Mineral

Copper Mining and Processing: Processing

The resulting "pregnant" leach solution of sulfuric acid and copper sulfate is collected in a small pool. The copper compound can now be seen at concentrations of between 60-70%. The second step is solvent extraction, in which two immiscible (un-mixing) liquids are stirred and allowed to separate, causing the cooper to move from one liquid to the other. The pregnant leach solution is mixed
