EXTRACTION OF SODIUM . On industrial scale sodium metal is extracted by "Down''s Process". PRINCIPLE. Down''s Process is based on the electrolysis of fused NaCl. CONSTRUCTION OF DOWN''S CELL Down''s cell consists of a rectangular container of steel. Inside of the tank is lined with firebricks.
The most significant problem, however, is the low extraction efficiency for the recovery of copper cyanide from solutions containing high copper and/or thiocyanate and the continuous decrease in the extraction efficiency due to the increase in CN:Cu ratio through each extraction stage (copper content decrease with essentially unchanged free
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important byproduct of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching
Extraction of Aluminium by Electrolysis. Edited by Jamie (ScienceAid Editor), Taylor (ScienceAid Editor), SmartyPants, Aluminum is extracted from aluminum oxide by a process called electrolysis. To visualize the process of electrolysis please refer to the diagram above.
From its original home buried underground in a mine to its use in a finished product such as wire or pipe, copper passes through a number of stages. On the periodic chart of elements it is identified by the symbol "Cu". 2. Mining Methods. Copper ore is extracted using two basic methods of mining open pit or underground mining. 3
4a. The extraction of copper from copper ores and its purifiion by electrolysis: How is copper extracted? how is copper purified? What is the state of copper ore reserves? Copper can be extracted from copper–rich ores by heating the ores in a furnace (smelting) and the copper can be purified by electrolysis. However, the supply of copper–rich (high grade) ores is limited.
Extraction and refining Extraction, concentration and refining of PGMs require complex, costly and energyintensive processes that may take up to six months to produce refined metal from the time the first PGMbearing ore is broken in a mine. 1 Chamber of Mines of South Africa, Annual Report 2012 figure does not include recycling.
Steps of Extraction of Metals. Concentration of ores: Removal of impurities, such as soil, sand, stone, silies, etc. from mined ore is known as Concentration of Ores. Ores which are mined often contain many impurities. These impurities are called gangue. First of all, concentration is done to remove impurities from ores.

Oct 03, 2016 · General Principles and Processes of Isolation of Elements is the most important chapter of CBSE Class 12th Chemistry. This chapter number 6th of NCERT Class 12th Chemistry book. Questions based on
Isolation of elements in Chemistry class 12 aims to teach the students about various processes of extraction of metals from ores. Very few metals such as the noble metals, i.e., Gold, Silver, and Platinum etc. are present in their original metallic forms in nature.
Electrolytic extraction of copper, molybdenum, and rhenium was conducted successfully at 1500 K using an electrolyte composed of alkalineearth, rareearth, and copper sulfides. The addition of a rareearth metal sulfide component to the electrolyte increased the faradaic efficiency and the recovery/isolation of sulfur as the anodic product.
