EXTRACTION OF COPPER

EXTRACTION OF COPPER On industrial scale copper is extracted from its sulphide ore known as copper pyrite (CuFeS 2) by smelting method STEPS OF EXTRACTION For more , Roasted ore is then mixed with coke and sand and is fed into a blast furnace Hot air.

METALLURGY OF COPPER-EXTRACTION OF COPPER-BLISTER

Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting Ores containing 4% or more copper are treated by smelting process Very poor ores are treated by hydro-metallurgical process , The concentrated ore is then roasted in a furnace in the presence of a current of air Sulphur is oxidized to SO2 and impurities of.

Refiner

Abyss - Wiki notes: Added recipes for the refiner, including the ability to refine certain underwater materials (Cyto-Phosphate, Crystal Sulphide) Visions 176 - Fixed an issue that could cause Big Ball to become permanently stuck in a refiner output (this fix prevents any new occurrences, existing blocked refiners continue to be blocked).

Pyrite

The mineral pyrite (/ ˈ p aɪ r aɪ t /), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide) Pyrite is considered the most common of the sulfide minerals Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname.
