Extraction and recovery of lithium | Condorchem Envitech
The extraction of lithium brines is carried out by pumping and its concentration by means of adsorption using a selective adsorbent, or by evaporation in shallow pools built for this purpose. The evaporation, in addition to raising the concentration of the salts, causes some of these to be precipitated when saturated.

Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel concentration greater than 99%. Electrorefining A second common form of further refining involves the leaching of the metal matte into a nickel salt solution, followed by the electro-winning of the nickel from solution by plating it onto a cathode as electrolytic nickel.

Extraction of Tin/ Stannum-Tin- - Metalcess
Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.8-7g/cm 3, density larger than most of gangue.Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.

Gold Extraction & Recovery Processes
In generals, the concentration of gold includes three stages: roughing, cleaning and scavenging. The reason of concentration is to separate the raw material into two products, concentrate and tails. Ideally, in free gold recovery, all the gold will be in the concentrate and the other part will be in the tails.

Extraction of Metals. Now we already saw how the ore of a metal is concentrated to remove impurities known as gangue. After concentration of ores, we must now extract metal from in it. This step will give us metal in its pure form i.e. the native form of metal. First, we must convert the ore to a suitable form.
