Statement

Quantitative x-ray diffraction (XRD) was performed on tailings samples to determine individual mineralogical and compositional phases. The finely-powdered (<70 μm) samples were scanned on a Bruker General Area Detector Diffraction System at the University of Southampton, using CuKα radiation and a scan range from 5 to 90° (2 Theta), a 0.03° (2 Theta) step size and a data collection time of 10 s per step. Major element analysis of all samples was determined by x-ray fluorescence (XRF) using a using the PANalytical AXIOS Max wavelength dispersive instrument at the University of Plymouth. Loss on ignition (LOI) was independently calculated as a quality control for the fusion method using an initial sample weight and heating to 1050 °C for 1 hour. LOI was calculated using equation: LoI (%) = (Ws - WA)/(Ws - Wc) x 100, where Ws = Crucible + sample dried at 105°C (g), WA = Crucible + ignited sample (g) and Wc = Preconditoned crucible (g). Total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC) and sulphur (S) contents of tailings and slags were measured using a LECO CS225 elemental analyser at the University of Aberdeen. The median grain size and grain size distribution (GSD) was measured using dry sieving techniques (for the coarser slag samples), and by laser grain-size analysis (for all fine tailings). Sieve pan sizes range from <63 µm to ≥4750 µm. Fine tailings samples were measured to a high precision using a Malvern Mastersizer 3000 laser diffraction particle size analyser at the University of Southampton.
