Copper Extraction from Sulfide Ores Latest Contents

EXTRACTION OF COPPER FROM SULPHIDE ORES Copper is mostly extracted from the sulphide ore, copper pyrites, by means of the following two processes: i-Smelting process ii-Hydrometallurgical process SMELTING PROCESS Modern copper metallurgy is based on the smelting process. Following steps are involved: i. CONCENTRATION OF THE ORE The finely powdered ore is concentrated by froth

Copper Mining and Extraction Sulfide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag)

How is Copper Extracted from Its Sulphide Ore?

2021-3-16  Copper is a metal that is present low in the reactivity series. It mainly occurs in nature in the form of sulphide ore which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting. The obtained oxide is then reduced with carbon or any other suitable reducing agent to obtain the metal.

In the extraction of copper from its sulphide ore, the

A slag is an easily fusible material which is formed when gangue still present in the roasted or the calcined ore combines with the flux. For example, in the metallurgy of iron, CaO (flux) combines with silica gangue to form easily fusible calcium silicate (CaSiO 3) slag. CaO + SiO 2 → CaSiO 3 (slag)

Extraction of copper directly from sulphide ore is less

In the extraction of copper from its sulphide ore, the metal is finally obtained by the reduction of cuprous oxide with. asked Dec 23, 2018 in Chemistry by sonuk (44.4k points) processes of isolation of elements; neet; 0 votes. 1 answer.

extraction of metals from sulphide ores

the extraction of metals from sulphide ores Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores. More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s).

The extraction of metals from sulphide ore involves:

Only sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. Reduction with carbon or roasting is a process of heating of sulphide ore to a high temperature in the presence of air.
