Due to the fact it truly is incredibly difficult to quantify Fe sulfide species with QemSCAN, petrography evaluation was performed working with a transmitted and reflective light microscope on both ore types. In line with the analysis of thin sections of Ore B, 1.5 of Tetradecyltrimethylammonium References pyrite particles had been defined as framboidal with a size selection of 0.01 mm. The marcasite particles had been observed as alteration and weathering minerals in an quantity of two , using a size variety as much as 0.three mm. In some fragments, the pyrite crystals have been immersed within a second generation of pyrite. In other fragments, the pyrite was intergrown with sphalerite (Figure 3a), along with the two minerals formed crus-Minerals 2021, 11, x FOR PEER Review Minerals 2021, 11, 1218 Minerals 2021, 11, x FOR PEER REVIEW6 6 of 13 of 12 6 ofOre A/-20 + 10 Ore A/-20 + 10 Ore B/+38 Ore B/+38 Ore B/-38 + 20 Ore B/-38 + 20 Ore B/-20 + ten Ore B/-20 + 1081.74 81.74 77.01 77.01 51.09 51.09 44.39 44.tiform intergrowths.
