Abstract (en)
[origin: WO2017068445A1] A method for determining adhesion characteristics of coatings disposed on the surfaces of iron ore pellets for use direct reduction processes is presented. A coating index is determined by measuring the percent reduction in the thickness of a coating layer after agitation forcibly contacting the coated iron ore pellets with each other. Coated iron ore pellets having optimized adhesion characteristics and reduced agglomeration tendencies for use in direct reduction processes are also provided.
