— The global shift towards renewable energy sources and the accelerating adoption of electric vehicles EVs have brought into sharp focus the indispensable role of lithium ion batteries in contemporary energy storage solutions Fan et al 2023; Stamp et al 2012 Within the heart of these high performance batteries lies lithium an extraordinary
In China there is less copper resource suitable for hydrometallurgical process and therefore the output from this process accounts for only 5% Leaching Leaching of low grade copper ore can be done in dump leaching or in situ leaching process but dump leaching is used more often The leaching agent is diluted sulfuric acid solution
WhatsApp
— Later attempts for in situ recovery of base metals have been undertaken In the in situ leaching process a leaching solution is injected into a subsurface ore body where valuable metals such as uranium or copper are dissolved from the ore The pregnant leach solution PLS is pumped to the surface where metal extraction takes place

— Likewise the benefits of the carbon in leach CIL process compared with leaching and carbon in pulp CIP have been clearly demonstrated both experimentally and in practice even without the presence of interfering preg robbing constituents in the ore The CIL process results in improved conditions for gold dissolution as a result of the
WhatsApp
— In the second century BC people discovered how to replace the copper in copper sulfate solution by using iron For example in graphite ore processing the intent of mineral processing is not to make the ore finer and instead graphite should be made in large sheets as far as possible provided that adequate graphite concentrate grade is
WhatsApp
— Bauxite is a rock type that is used to produce metallurgical grade alumina and chemical grade alumina/aluminum hydroxide using the Bayer process During this process the finely ground bauxite ore is digested under pressure in a strong caustic sodium hydroxide solution at temperatures ranging from 100 to 260 °C
— Under a certain E pH condition nickel and cobalt in mineralogical phase can enter into the solution by forming ammine complexes in ammonia—ammonium solution while other impurity metals remained in the residue which overshoots the metal gross from ore processing and matte refining sources combined Nickel production from the

Copper can be extracted from non sulfide ores by a different process involving three separate stages Reaction of the ore over quite a long time and on a huge scale with a dilute acid such as dilute sulfuric acid to produce a very dilute copper II sulfate solution Concentration of the copper II sulfate solution by solvent extraction
WhatsApp
— Iron ore is essential in steel making; however high grade ores have diminished making low grade ores inevitable These low grade iron ores need further beneficiation to upgrade the iron content Currently traditional physical and chemical methods are utilized and are not environmentally friendly Bio beneficiation techniques
