2. Hydrometallurgy - Wikipedia

   en.wikipedia.org/wiki/Hydrometallurgy

   Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. [1] [2] Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy. Hydrometallurgy is typically divided into three general areas: Leaching

3. Non-ferrous extractive metallurgy - Wikipedia

   en.wikipedia.org/wiki/Non-ferrous_extractive...

   Unit processes are usually broken down into three categories: pyrometallurgy, hydrometallurgy, and electrometallurgy. In pyrometallurgy, the metal ore is first oxidized through roasting or smelting. The target metal is further refined at high temperatures and reduced to its pure form.

4. Extractive metallurgy - Wikipedia

   en.wikipedia.org/wiki/Extractive_metallurgy

   Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...

5. Solvent extraction and electrowinning - Wikipedia

   en.wikipedia.org/wiki/Solvent_extraction_and...

   Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent.

7. Leaching (metallurgy) - Wikipedia

   en.wikipedia.org/wiki/Leaching_(metallurgy)

   In the 1950s, pressure hydrometallurgy was developed for the leaching of multiple different metals, such as sulfide concentrates and laterites. [4] Particularly at the Mines Branch in Ottawa (now known as CANMET ), it was demonstrated that pyrrhotite - penthandite concentrate could be treated in autoclaves , with the resulting nickel in a ...

8. Tank leaching - Wikipedia

   en.wikipedia.org/wiki/Tank_leaching

   Tank and vat leaching involves placing ore, usually after size reduction and classification, into large tanks or vats at ambient operating conditions containing a leaching solution and allowing the valuable material to leach from the ore into solution.
