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.

Native gold is an element and a mineral. It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties - some of which are unique to gold. No other element has more uses than gold. All of these factors help support a price of gold that is higher than all but a few other metals.

In a mining field miners found an ore called fools gold whose chemical formula is FeS2 Which method has to be carried out to convert concentrated ore to its. ... Roasting is done for converting sulphide metal ore to its oxide. The given ore contains sulphide. Hence, roasting is done.
Apr 24, 2017· Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
The more active (or reactive) a metal is, the more stable the compound it forms and the greater the energy required to produce the metal from its ore. Very active metals ( Group 1, Group 2 and aluminium) require electrolysis to extract the metal while very inactive metals like gold and silver can occur in nature as the element so require no ...
Gold has been treasured since ancient times for its beauty and permanence. Most of the gold that is fabricated today goes into the manufacture of jewelry. However, because of its superior electrical conductivity and resistance to corrosion and other desirable combinations of physical and chemical properties, gold also emerged in the late 20th century as an essential industrial metal.
This is a complex gold ore with oxide gold in a quartz vein with sulfide gold. The sulfide gold is too fine to see, it was probably hydrothermally deposited as a replacement for the iron and pyrites (dark holes) that reduced and oxidized to iron (staining the ore), leaving cavities for gold …
