Hard Rock Lithium Processing
8.03%. Due to its high lithium content, spodumene is considered the most important lithium ore mineral. A typical run of mine ore can contain 1-2% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li 2 O (75% - 87% spodumene). Higher grade concentrates with 7.6% Li 2 O and low iron content are
Solvometallurgical process for extraction of copper from …
Abstract. Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and …
The Extraction of Copper
The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: [2CuFeS_2 + 2SiO_2 +4O_2 rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 label{1} ]

Iron- and Steel-Making Process
Blast furnace iron making is the most popular process for extraction of iron from its ores. Other well-known processes are EAF and Direct Reduction Iron (DRI) processes. However, blast furnace will continue to be the most efficient route to produce pig iron for its high productivity and cost optimization, for many years to come [1, 2].
Iron (Fe) Ore | Minerals, Occurrence » Geology Science
Mining and processing: Iron ore is typically mined through open-pit or underground mining methods, depending on the depth and location of the deposit. After extraction, iron ore is processed to remove impurities and obtain the desired iron content through crushing, grinding, magnetic separation, and other beneficiation techniques.

Iron Ore Processing: From Extraction to Manufacturing
The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
