Sulfamic acid (SA), which possesses a zwitterionic structure, was applied as a leaching reagent for the first time for extracting copper from copper oxide ore. The effects of reaction time, temperature, particle size, reagent concentration, and stirring speed on this leaching were studied. The dissolution kinetics of malachite was illustrated with a three-dimensional diffusion model.

Jan 17, 2015· Y. M. Zhao et al. 12 However, when 1% Na 2SO 3 was added, the copper extraction wasn't down until 650 ˚C. This indicated that Na 2SO 3 can improve the degree of sulfating at high temperature. One possible reason is that the addition of Na 2SO 3 could prevent the decomposition of copper sulfate. Another possible reason is the exist of some com-

This paper deals with the investigation of column leaching of low-grade ores from the copper mine Cerovo, Serbia (the approximate Cu content in the ore ranges from 0.2 - 0.3 % with >10 % copper in the form of oxide minerals). The leaching experiments were performed using sulphuric acid solutions, whereby the kinetics of copper

Jun 28, 2017· Separate experiments also proved the ability to selectively reduce rhenium or molybdenum without reducing copper, based on their differing decomposition energies. Industrial potential Important strategic and commodity metals including, copper, zinc, lead, rhenium, and molybdenum are typically found in sulfide ores and less commonly in oxide ...

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.

May 16, 2021· After successfully extracting copper from an intact sulfidic porphyry Cu ore drill core sample, the group is confident the idea will also work in the field, not only for …

A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper. The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching of ...

Three different stages are involved when extracting copper from non-sulphide ores. 1. Over a very long time and on a vast scale, the reaction of the ore with a dilute acid (such as dilute sulphuric acid) produces an extremely dilute copper sulphate by solvent extraction. 2. a. By solvent extraction, the copper sulphate is concentrated.

Jan 01, 2018· The dissolved copper was reduced to copper metal and obtained by filtration. It was confirmed by XRFS analysis that, the metal purity was found to range between 60 and 80% depending on the ore used. In another experiment, chicken waste solution was used to extract copper from the ore.

Mar 16, 2017· In a crucible, we added copper carbonate and the total weight of both is 37.04g. After, we heated the crucible with the copper carbonate. It was easy to judge when the reaction had taken place as the colour of the substance had changed from the light green of copper carbonate to the black of copper oxide.After we observed this, we weighed the copper oxide and we notified the result …
