Extraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides.


Gold mines produce rough gold, called a dore bar. These bars are typically about 80 percent pure gold. The gold is then sent to a refinery, where it is refined into gold of different forms and purity.

PBS (phosphate buffered saline) is a common buffer solution used in the laboratory. It is an isotonic and non-toxic buffer that is meant to mimic the osmolarity and ion concentrations of the human body. PBS is used for immunoassays, for sample dilution, for protein purification, and as a wash buffer in cell cultures.

Lead | Pb (Element) - PubChem

Lead has been known since ancient times. It is sometimes found free in nature, but is usually obtained from the ores galena (PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4).Although lead makes up only about 0.0013% of the earth's crust, it is not considered to be a rare element since it is easily mined and refined.
