AN EXAMPLE OF THE USE OF AN INDUSTRIAL BY-PRODUCT: THE APPLICATION TO ROAD-MAKING TECHNIQUES OF THE REJECTS FROM THE ENRICHMENT OF CALCAEROUS IRON ORE AT METZANGE IN LORRAINE

LORRAINE IRON ORE HAS AN IRON CONTENT OF AROUND 30 PER CENT. THE OPERATION OF ENRICHING BY MAGNETIC SEPARATION GIVES REJECTS OF GRANULARITY 0/2 MM., WHOSE WATER CONTENT IS NEGLIGIBLE. WORK HAS BEEN CARRIED OUT IN DIFFERENT LABORATORIES WITH A VIEW TO MAKING USE OF THESE REJECTS, AND THIS WORK HAS MADE IT POSSIBLE TO DETERMINE THE AVERAGE CHARACTERISTICS OF THIS MATERIAL. ITS USE FOR ROADMAKING PURPOSES SEEMS TO BE ESPECIALLY INDICATED, IN PARTICULAR IN THE FORM OF MIXTURES WITH GRANULATED SLAG (RECOMMENDED CATALYST : LIME). A SMALL EXPERIMENTAL WORKING SITE SET UP IN 1965 IN A STEEL WORKS AND IS THE SUBJECT OF A DETAILED REPORT. MEASUREMENTS OF DEFLECTIONS, AND CORE SAMPLINGS, WERE FAVORABLE. /AUTHOR/
