The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis (electrowinning) for low grade ores, or by the carbon reduction method of smelting for higher grade ores. The process of extracting copper from higher grade sulfide ores involves:
You can obtain copper from malachite ore but not by precipitation. Basically, you can decompose a small amount of malachite by heating it,) to obtain copper oxide. You then reduce the copper (oxidized in malachite) by heating it to metallic copper...
Laboratory extraction of copper from malachite using sulphuric acid Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Laboratory extraction of copper from malachite using sulphuric acid, quarry, aggregate, and different kinds of minerals.
Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.
The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning). Advantages of these processes are: Much less energy is used than in traditional mining. No waste gases are given off. Low capital investment. Ability to be operated economically on a small scale.
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, liquid-to-solid ratio and agitation rate on the copper and iron percentage were investigated.
Jun 07, 2021· Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper…
Extracting Copper from Malachite Introduction This experiment involves producing copper from copper ore (malachite). The composition of malachite is mainly copper carbonate (CuCO 3). This experiment involves heating the copper carbonate with carbon. Safety Wear eye protection – crucible may emit sparks! Copper compounds are harmful to your ...
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, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
In the leaching step of the study, the effects of reaction temperature, particle size, and stirring speed on copper leaching from malachite ore were investigated. Maximum copper extraction (98%) from malachite ore was achieved at experimental conditions of …
