The optical microscopy images of the raw ore (Fig. 1) show the dissemination characteristics of the main sulphide minerals. Galena associates closely with sphalerite and pyrite (FeS 2) and has a grain size of approximately tens of micrometres (Fig. 1 b and 1c). Flotation exhibits more obvious advantages in the recovery of fine-grained minerals.

Besides bioleaching using Acidithiobacillus bacteria and bioremediation using SRB, many mining organisms which inhabit ore deposits find applications in mineral beneficiation such as microbially induced flotation and flocculation.Acidithiobacillus spp can be used also to bring about microbially induced flotation and flocculation of minerals. . Heterotrophic …

Pyrite does not have as strong and deep a yellow color as gold, and pyrite will form as crystals where gold does not. Pyrite Worth. Pyrite worth is not very substantial due to its abundance around the world. The price per carat of pyrite typically averages below $1 per carat. Larger pyrite crystals are still relatively cheap and can be ...

By enhancing the quality of lower-grade raw materials through beneficiation, downstream processes also become more viable. Various production routes are available to transform iron ore into liquid steel, as shown in Figure 1. The selected route depends to a large extent on the quality of the iron ore, energy source and related costs.
