Empirical model forbioextraction of copper

Abstract: The copper extraction in shaking bioreactors was modeled and optimized using response surface methodology (RSM). Influential parameters in the mesophilic bioleaching process of a lowgrade copper ore including pH value, pulp density, and initial concentration of ferrous ions were comprehensively studied.

This is not really one equation but two as the zinc ore is first converted to ZnO before being reduced. Reaction when Zinc Blende is heated in the air: 2 ZnS + 3 O2 → 2 ZnO + 2 SO2.

SX Solvent Extraction of Metals: A Design Manual

2020512&ensp·&enspCopper Recovery by Solvent Extraction. A common method of copper recovery from oxide ores is dump leaching in which the excavated ore is crushed and dumped on an impervious surface in "lifts" of anything from 10 to 100 ft deep. Sulphuric acid is sprayed onto the levelled off dump via a network of pipes designed to give even distribution.

Copper mining. Chemical reactions.

2014613&ensp·&enspAt this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite CuFeS 2.From the formula, it is clear that iron and sulphur have to be removed in order to produce copper.
