Mar 01 2014 · The present work describes an investigation of a chemical process for the recovery of copper and iron from malachite ore For the dissolution of copper and iron H 2 SO 4 was employed as well as H 2 O 2 as an oxidizing agent The effects of reaction temperature and time acid concentration liquidtosolid ratio and agitation rate on the copper and iron percentage were investigated

Extracting copper from Malachite ?Oxidation and reduction both occur together If one substance is oxidized another is reduced A process where oxidation and reduction are taking place

Chemistry Extracting Copper from Malachite We extracted Copper from Malachite using a displacement reaction Although electrolysis can also be used We used 5g of malachite and dissolved it in sulphuric acid this was to separate the sand and the copper because the copper dissolves into the solution but the sand remains separate View More Details

In order to extract copper from malachite the malachite must be heated to a high temperature This produces a fine black powder copper Oxide The copper oxide is heated again to a more extreme

The first mention of the systematic extraction of copper ore comes from about 3800 BC Malachite or green copper ore CuOH 2 •CuCO 3 is an important carbonate ore This produces an open pit that may grow to be a mile or more across The tanks are filled with an acidic copper sulfate solution which acts as anget price

extracting copper from malachite Extracting a metal from its ore134 Кб Copper can be extracted from its ores by reduction One of the common copper ores malachite which is composed of mainly copper carbonate CuCO3xCuOH2 is heated to produce copper oxide with the release of carbon dioxide

Copper Extruction From Malachite Ore This lab extracts the copper from an ore with the mineral malachite basically copper carbonate hydroxide Cu 2CO 3 OH 2 as people may have done it more primitively at the beginning of the copper age about 4000 BCE We are using malachite jewelry beads
