Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), th

In addition to its high concentration of lithium, lithium extraction from spodumene also typically offers lower capital costs and a shorter time from discovery to production in comparison to brine operations. Extracting Lithium from Spodumene. The extraction of lithium from spodumene ore requires a number of steps outlined below.
Dec 01, 2014· Lithium extraction from primary resources such as ores/minerals (spodumene, petalite and lepidolite) by acid, alkaline and chlorination processes and from brines by adsorption, precipitation and ion exchange processes, is critically examined. Problems associated with the exploitation of other resources such as bitterns and seawater are highlighted.

This process was so efficient and easy to implement that it has been considered the one and only method of extracting lithium from spodumene in the lithium industry. From there, two major steps can be pointed out. The first one is the lithium extraction from β-spodumene and the second is the decrepitation of α-spodumene.
From this plot, it can be seen that the final lithium extraction was much higher for the leaching of β-spodumene than for that of the α-spodumene. These results indicate the relative inertness of α-spodumene or its high resistivity to biodegradation and/or to chemical attack. As a consequence, in the further studies only β-spodumene was used.
Place these products in the extraction process in ascending order of copper content. Use the flow chart as a guide: Matte Ore Cathode copper Blister Anode copper Copper concentrate Fire refined copper; Use a periodic table to find the atomic masses of the elements in cuprite and chalcocite. Then work out the percentage of copper in each mineral.
