EnvironOxide-modifying natural processes to produce high-quality iron oxide pigments

摘要

For centuries mankind has utilised naturally occurring iron oxides as colouring agents. It is only in the last century that people have developed ways to chemically synthesise these natural reactions. More recently, the Hoover Color Division of Cathay Industries has worked in conjunction with Iron Oxide Recovery to modify a naturally occurring process to produce a series of unique iron oxide pigments. Not only is this EnvironOxide? range a good source of colour, it is also a by-product of a successful reclamation project.
