The Extraction of Copper
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
Acid-Base Extraction
Acidity; Contributors; An acid-base extraction is a type of liquid-liquid extraction.It typically involves different solubility levels in water and an organic solvent. The organic solvent may be any carbon-based liqiuid that does not dissolve very well in water; common ones are ether, ethyl acetate, or dichloromethane.

FIGURE 2 Flow chart for the two-base extraction of benzoic acid, 4-nitroaniline, and N-(4-nitrophenyl)benzamide. Balmer 8 11) The sequence of bases for the two-base extraction is critical to separating the benzoic acid from the 2-naphthol. Benzoic acid has a pKa of 4.17, while 2-naphthol has a pKa of 9.5.
3: Extraction of Caffeine (Experiment)
Extract with 35 mL of methylene chloride. In a departure from normal procedure, it will be necessary to vigorously shake the separatory funnel in order to extract the caffeine. First, relieve the pressure buildup as soon as you mix the two liquids. Then shake vigorously for 10 seconds and relieve pressure, repeat the shaking two more times.
