The first step is to heat the bauxite ore to temperatures of 200°c along with a sodium hydroxide solution. This will convert the aluminium oxide to a solution of sodium aluminate. The silica will dissolve itself in the process. The chemical equation is Al 2 O 3 + 2 NaOH → 2 NaAlO 2 + H 2 O

Froth flotation is mainly operated under two common techniques : 1. Direct floatation technique - In this method, the mineral sticks to the air bubble and the remaining gangue settles down at the bottom. 2. Reverse floatation technique - In this method, the gangue sticks to the air bubble and ore particles settle down in the bottom.

Hence, after flotation, a magnetic separation operation was introduced to improve once again the available alumina grade in the concentrate. The pilot plant concentrate reached 42.3% of available alumina, increased to 54.0% after removal of the magnetic minerals. The available alumina content required by the alumina refinery, in this case, was 42%.

For treating such a new ore, bulk Cu-Pb flotation followed by Zn flotation has been recommended (Sehlotho et al., 2018). An example of a sequential Cu-Pb-Zn flowsheet is given in Fig. 14 . A first flotation stage is carried out at low pH (pH 6), in which the copper sulphide is floated while both galena and sphalerite are depressed.

During the flotation process of some ores, these substances are added which activate or depress the flotation property of the minerals and thus help in the separation of minerals present in the ore. For instance, galena (PbS) is usually associated with sphalerite (ZnS) and pyrites,NaCN. Hence all options are correct.
