Abstract
A micro-agglomerate of fines of a material that is predominantly titanium dioxide in which the fines are bound in the micro-agglomerate by a polysaccharide gum or cellulose derivative and in which the micro-agglomerate has been heated in the temperature range 250-600° C. so that the polysaccharide gum or cellulose derivative is an effective primary binder of the fines when the micro-agglomerate is subjected to high temperature gas flow conditions equivalent to those in the Chloride Process. Also disclosed is a method of agglomerating fines of a material that is predominantly titanium dioxide.

A method of agglomerating fines of a material that is predominantly titanium dioxide, comprising:
- forming the fines into micro-agglomerates in which the fines are bound in the micro-agglomerates by a polysaccharide gum or cellulose derivative, and
- heating the micro-agglomerates in the temperature range 250-600° C. so that the polysaccharide gum or cellulose derivative is an effective primary binder of the fines when the micro-agglomerate is subjected to high temperature gas flow conditions equivalent to those in the Chloride Process.

A micro-agglomerate of fines of a material that is predominantly titanium dioxide in which the fines are bound in the micro-agglomerate by webs that comprise a polysaccharide gum or a cellulose derivative, the webs having a respective longitudinally central region of a minimum thickness substantially smaller than the size of the respective bound fines particles.
