The carboxylmethyl starch modified with nano-CaCO3 has been identified as an alternative binder in iron ore pelletization. This study aims to further clarify effects of nano-CaCO3 on the adsorption of carboxymethyl starch (CMS) onto magnetite particles. Variables influencing the adsorption capacity of CMS, such as solution pH, initial concentration, the ratio of nano-CaCO3 to CMS and adsorption time,...
This study aimed to identify the carboxymethyl starch modified with nano-CaCO3 (CCMS) as an alternative binder in iron ore pelletization. Pelletization results showed that all wet, dry, preheated and fired pellets produced with CCMS met with the required values of strengths. The total Fe content of pellets also had a 1.04% increase by replacing 2% bentonite with 1% CCMS. FTIR and zeta potential tests...
