EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper pyrite CuFeS2 by smelting. Ores containing 4 or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process. EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper.

The workflow begins with cell lysis, and the steps involved in sample preparation are designed to move the protein containing fraction from the initial biological source into a homogeneous solution, while preserving the in vivo state of the protein. Obtaining high quality lysates is critical for the successful outcome of downstream applications.
Order the steps involved in fractional crystallization 1. , after entering through the bottom of the magma chamber, reaches the top of the chamber where temperatures are lower. 2. Magnesium-and iron-rich minerals begin to crystallize 3. Mineral crystals, having a higher density than liquid magma, sink to the bottom of the magma chamber 4.
The three steps involved in extraction are1 Concentration of the ore to remove impurities.2 Reduction of the ore to get the metal.3 Purification of the ore.
The extraction of rubidium from gold waste from the Mouteh processing plant in Iran by a three-step process acid washing, followed by salt roasting and water leaching was optimized. The acid washing step for removal of impurities was found to be optimal at 85 C and 5 h, using 5 M nitric acid.

Can Gold be Extracted from Seawater with pictures Dec 12 2019 Despite a number of hoaxes and scams serious interest in the subject continues as reserves of gold on the Earth s surface diminish. Extraction. Due to the extreme dilution of gold in seawater there is currently no economically viable method of obtaining the metal from this source.
The various steps involved in the extraction of gold are 1. The concentrated ore is roasted to remove all the oxidisable impurities. 2. Treatment with KCN . The roasted ore is then treated with a solution of sodium cyanide or potassium cyanide for some days. In the presence of atmospheric oxygen, gold dissolves in the form of a complex.
The additional steps taken simply set the stage so the tooth can then be removed using the same basic principles explained above. Despite the fact that the added steps are surgical in nature, using them may actually serve to decrease the overall level of trauma created by the extraction process.
