Abstract

Scaling prevention in the wet processing of calcitic and dolomitic phosphate rock

Author(s): S.Chouai, P.A.Young

The aim of the present study is to investigate the possibility of scale prevention in the wet processing of calcitic and dolomitic phosphate rock. The mechanism of scaling is known in many field of engineering by the name fouling. The term fouling, originally a descriptive expression used in the oil industry, became established in the literature tomean any undesirable deposit on heat exchange surfaces which increases resistance to heat transmission. Such deposit is the set down of matter originally present in the fluid on the wall of flow channels. The work described in this study is confined to calcium carbonate scaling and the prevention of scaling from a suspension of phosphate rock.
