Our iron ore operations provide customers with niche, consistent quality ore, ideal for sintering due to its high Loss on Ignition (LOI). VIEW SITE. EXPLORING NEW. POSSIBILITIES IN MINING. Build, pilot and scale. frontier technologies. In partnership with New Lab, this …A typical iron ore analysis should include a loss-on-ignition (LOI) determination at 1000 C, normally undertaken by Thermogravimetric Analyser (TGA). The LOI is due to the loss of water from hydrated minerals (goethite, gibbsite and kaolinite), decomposition of carbonates (calcite, siderite and dolomite) and the volatilisation of organic compounds.

High LOI in iron ore fines has an adverse affect during pellet induration process.3000 E. Both samples were also characterized by Loss-on-ignition(LOI), XRF and XRD. The loss on ignition (LOI) was determined by placing 4 grams of sample in a 1000 C furnace for 60 minutes and reporting the LOI on an as received basis. The chemical composition analysis was completed using a wavelength dispersive X-ray Fluorescence (WD-XRF)
