The Bayer process is a chemical process that is used to extract alumina from bauxite, which is the primary source of aluminum. This process was developed by Karl Bayer in 1888 and has since become the most widely used method for producing alumina.
Definitions
The Bayer process is a chemical process that involves the extraction of alumina from bauxite. The process involves the use of caustic soda, which dissolves the alumina from the bauxite and leaves behind the impurities. The alumina is then precipitated out of the solution and washed to remove any remaining impurities.
Origin
The Bayer process was developed by Karl Bayer in 1888. Bayer was a chemist from Austria who was working at the time for the Austrian chemical company, the Austrian Chemische Fabrik. The process was initially developed as a way to extract alumina from bauxite, which was a waste product of the aluminum industry at the time.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, the Bayer process is defined as “a process for producing alumina from bauxite by digesting it with sodium hydroxide solution at elevated temperatures and pressures and then precipitating the alumina from the solution.”
The Oxford English dictionary defines the Bayer process as “a method of extracting alumina from bauxite by treating it with caustic soda at high temperatures and pressures, followed by precipitation of the alumina from the solution.”
Associations
The Bayer process is closely associated with the aluminum industry, as it is the primary method used to extract alumina from bauxite, which is then used to produce aluminum.
Synonyms
Some synonyms for the Bayer process include the Bayer method, the Bayer extraction process, and the Bayer alumina process.
Antonyms
There are no antonyms for the Bayer process, as it is a specific chemical process with no direct opposite.
The same root words
The Bayer process is named after its inventor, Karl Bayer. The root word “Bayer” is derived from his last name.
