AN INDUSTRIAL COPPER SOLVENT EXTRACTION …

The process has two input flows, pregnant leach solution (PLS) and lean electrolyte (LE), and one recycling flow, the organic solution. In the extraction stage, the copper is extracted from PLS to barren organic (BO) solution. In the stripping stage, copper is stripped from the loaded organic (LO) to lean electrolyte (LE) solution.

Pregnant Leach Solution

This flow sheet is for chloride leach pregnant leach solution and chloride electrowinning aqueous electrolyte. Sulfate solvent extraction is similar but (i) the aqueous solutions are both sulfates and (ii) the O 2 produced during electrowinning is not recycled to leach.

Solvent Extraction

The LIX ® range of solvent extractants are applicable to leach solutions with a wide range of copper tenors, pH and impurity levels. They have been successfully used to concentrate and purify pregnant leach solutions produced from heap/dump leach, agitation leach and concentrate leach processes.

Copper recovery using leach/solvent …

Pregnant leach solution flowing from the bottom of the heap was collected in a pond created by placing a dam downstream from the leach area. The Bluebird copper SX plant was built similar to existing uranium SX plants with tall, single baffled mixers and long narrow settlers.

Copper SX-EW technology

In the solvent extraction phase of the process, incoming pregnant leach solution (PLS) is concentrated and purified, and a pure electrolyte is then used in electrowinning to produce chemically and physically high quality copper cathodes.
