Wendell Dunn A family of chlorine beneficiation processes based on selective chlorination of ores in a fluidized bed. Developed by W. E. Dunn of Chlorine Technology in Australia in the 1970s, primarily for beneficiating ilmenite. The first such commercial ilmenite beneficiation plant, completed in 1991, was that of Bene-Chlor Chemicals Private, Madras.

Not all diaphragm plants would consider conversion. In the case of plants where the diaphragm caustic soda from the cells is fed to a downstream plant there is no economic driver to convert. Indeed, ICI Chlor-Chemicals has a diaphragm plant where the sole requirement is the use of the diaphragm cell caustic as a reagent for treating raw brine for multiple chlor-alkali plants, ammonia soda plants and evaporated salt plants. 

ICI Chlor-Chemicals Electrochemical Technology Business can provide the knowhow, experience and membrane technology for any of the chosen options. 

ICI Chlor-Chemicals has four chlorine production sites Lostock and Runcorn in the north-west of England, Wilton in the north-east and Wilhelmshaven in Germany. These sites operate a range of cell technologies including mercury, diaphragm and membranes. 

This work is part of an overall instrumentation and control improvement strategy which is being pursued by ICI Chlor-Chemicals with the aim of reducing the amount of manual control required and improving energy efficiency. 

The completed model has been a vital part of a programme of instrumentation and control improvement projects at the ICI Chlor-Chemicals Runcorn plant. It has been of assistance in all stages of the project including ... 

Another possible method of increasing the TiOz content of ilmenite is by partial chlorination of the iron in the presence of carbon. This is operated on a large scale by several companies [2.24], [2.25], The most important companies which are producing synthetic rutile are located in Australia (Renison Goldfields Consolidated, Tiwest, Westralian Sands), United States (Kerr-McGee Synthetic Rutile), India (Ke-vala Minerals and Metals Ltd., DCW Ltd., Bene-Chlor Chemicals Ltd.), and Malaysia (Hitox). In 1994 production of synthetic rutile was about 0.6 x 106 t of contained TiOz.
