SAHRA - Home Water Testing

If the water is classified as very hard (10.5 or more grains per gallon or 180 or more mg/L of calcium carbonate), a house point-of-entry (POE) treatment may be needed. Otherwise, only the hot water supply should be treated to reduce formation of calcium deposits (scale) in the water heater and pipes.

Types of Extraction | S-cool, the revision website

Methods of extraction Many metals are found in the Earth''s crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the

Leblanc process - Wikipedia

The Leblanc process was an early industrial process for the production of soda ash (sodium carbonate) used throughout the 19th century, named after its inventor, Nicolas Leblanc.It involved two stages: production of sodium sulfate from sodium chloride, followed by reaction of the sodium sulfate with coal and calcium carbonate to produce sodium carbonate.
