Abstract
The requirements of the orthop(l!dic plaster specified by the ·Indian Standard
specification can be satisfied only with high purity mineral gypsum or selenite. These
quality minerals are not available in abundance. To meet the demands for the product,
beneficiation studies were carried out with a substandard gypsum mineral from Jammu.
The method developed has shown the possibility of upgrading the mineral, otherwise
unsuitable for the purpose, to the desired degree so as to conform to the specification.
The plaster so prepared was found to have a better strength.
