removing of sulphur and iron from copper ore

removing iron ore from copper concentrate

Removal of sulfur in the reduction of iron-ore In lean coal and lignite, sulfur is predominantly present as organic compounds. According to experiments with a QMC-230 mass spectrometer and an IR absorption analyzer, the removal of sulfur in the reduction of iron-ore concentrates is hindered by the adsorption of sulfur-bearing gases and its

Copper Mining and Extraction Sulfide Ores

From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air.

Methods of Metal Recovery by Microorganisms (2 Methods)

For instance, chalcopyrite mainly contains 26% copper, 26% iron, 33% sulfur and 2.5% zinc. Bioleaching of copper ore (chalcopyrite) is widely used in many countries. This is carried out by the microorganism Thiobacillus ferrooxidans which oxidizes insoluble chalcopyrite (CuFeS 2 ) and converts it into soluble copper sulfate (CuSO 4 ).

Copper Sulfide an overview ScienceDirect Topics

The leaching of copper sulfide and copper oxide ores entails partial dissolution to cupric sulfate with sulfuric acid and iron sulfate. The presence of pyrites in many ore deposits, and its reaction with water and oxygen to form iron sulfate and sulfuric acid, creates an important source of acid.

Environmental Guidelines for Copper Smelting

The matte (copper-iron sulfide) from the furnace is charged to converters where the molten material is oxidized in the presence of air to remove the iron and sulfur impurities (as converter slag) and to form blister copper. Blister copper is further refined as either fire-refined copper or anode copper

Innovations: Introduction to Copper: Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Slag Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of

Sulfide Ore an overview ScienceDirect Topics

A basic principle of many processes for extracting copper and nickel from sulfide ores is to overlay the molten ore or matte with a lime–silica–iron oxide slag and blow with air or oxygen. Some of the iron present in the ore oxidizes and as a result, partitions to the slag phase, while some of the sulfur is carried off as sulfur dioxide.
