SOLVEX - The Solvent Extraction Database has been
established at Warren Spring Laboratory, in association with a
consortium of member companies of the Mineral Industry
Research Organisation (MIRO), since 1974. The project was
originally initiated to fulfil the need for a comprehensive
source of quantitative information, on Solvent Extraction,
compiled into a standard format.
Originally the data were presented in an indexed loose
leaf form. Computerisation offered considerably enhancement
of both the value of the database and the facilities that
could be offered. However, many commercial databases
available today fail to provide a method for simple data
retrieval; they rely substantially on users familarising
themselves with, sometimes quite complex, query languages and
the precise structure of the database. Therefore to overcome
this problem the computerisation process for SOLVEX included
the development of a menu-driven user interface to allow
rapid, selective data retrieval and reporting.
At the start of the project the bulk of the data
concentrated upon distribution and kinetic data for the base
metals. Since the computerisation procedure has been
completed and to support the increasing industrial interest,
the range of data covered has been expanded to cover nearly all metals particularly the exotics.
The database is not restricted to performance data alone,
a significant proportion of the data is concerned with the
physical properties of reagents, and on physicochemical data
such as viscosity, interfacial tension, solubility, specific
gravity and toxicity. In addition there are comprehensive
sections on commercial information and references.
The database provides a qualitative guide towards the
development of Solvent Extraction processes. It can be used
to eliminate unsuitable reagents and to help the process
designer define the optimum experimental conditions.
This paper details the structure and development of the
database. The benefits such a system offers to both the
process designer and reagent manufacturer are discussed.
Future plans for database development are outlined.
