Repeat of mineral liberation analysis of cassiterite, chalcopyrite, pyrrhotite, arsenopyrite, siderite, wolframite, and tourmaline in 9 samples

Objectives: To determine the mineralogy of 9 samples in total: 1 mill feed sample with 1.5% Sn (SFD, 3 size fractions 5-38, 38-150, >150 μm), 2 tail samples with 0.2-0.4% Sn (CFT and FSC, 2 size fractions each, 5-38 and 38-150 μm), 1 concentrate sample with 55% Sn (RFC, 2 size fractions 5-38 and 38-150 μm). This included full mineral liberation analysis for cassiterite, chalcopyrite, pyrrhotite, arsenopyrite, siderite (siderite-ferberite series) and tourmaline, as well as XRD analysis to cross check the mineral identification and mineral abundance.
