The simplified flotation flowsheet is given in Fig. 1. In this process, after desliming and sizing, the ore is conditioned with fatty acids and fuel oil at a pH of 9.0–9.5. Then, the apatite is first floated from silica and carbonates in the rougher stage at which 0.8–2.0 lb/ton of fatty acid and 1.0–4.0 lb/ton fuel oil are consumed.

Silica Minerals represent the group of minerals being composed of silicon and oxygen forming the chemical formula SiO 2. Silica can occur in macrocrystalline, crytocrystaline and amorphous form. Industry predominantly uses the crystalline form of silica, i.e. quartz. Silica is used as granular products containing the particle size range >63 µm.
