Solvent Extraction Plants: Thiele Diagram & …
Required copper tenor of advance electrolyte is the factor which determines the flowrate of strip liquor through the solvent extraction plant, consistent with temperature control requirements of the tankhouse and the sizing of coalescers or filter columns to remove entrained organic ahead of tankhouse operations.
Copper Recovery by Solvent Extraction Techniques
The capital cost of a solvent extraction plant depends on the throughput of leach liquor and not simply on the copper production rate. Higher concentrations of copper in the liquor are dealt with in the extraction section by increasing the concentration of the organic extractant in the organic phase while maintaining the same overall organic/aqueous ratio.
Copper Mining and Extraction: Oxide Ores
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 contained in the pregnant leach solution, exchanging them with hydrogen ions in the acid.

Copper production & environmental impact
The copper-bearing solution is collected and pumped to the extraction plant where it is purified. It progresses through a number of steps that combine an organic solvent or sulfuric acid to the solution until the copper concentration is high enough for effective electro-plating.
copper solvent process extraction hydrometallurgy
only in 1970, with the commissioning of the first copper plant in Arizona, USA, that solvent extraction was implemented for base-metal hydrometallurgy Now, as a mature technology at the turn of the millennium, solvent extraction is entering a new era: specialised extractants, more efficient contacting equipment, and advances in the up- and ...

Copper Mining and Extraction: Oxide Ores. After solvent extraction using organic solvents, the copper ions are stripped from the solution with a strong acid and leave a blue solution with a high copper content.This is called the rich electrolyte. 4. The electrowinning plant uses electrolysis to collect copper onto steel cathodes.
Control of an industrial copper solvent extraction …
A two level control strategy that stabilizes and optimizes the production of an industrial copper solvent extraction process is presented. The stabilizing layer consists of a multi-input–multi-output controller or two single-input–single-output controllers with additional four feedforward compensators that regulate the flow rates in the copper solvent extraction process.
