Keywords: flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the ore is exploited (Kabuda et. al., 2011).

The process is repeated several times and the heater is moved in the same direction. At one end impurities get con-centrated. This end is cut off. In this way, the impu-rities are swept from one end of the bar to the other. By repeating the process, ultra pure metal of silicon, germanium etc are obtained. Fig. Zone Refining Process

Answer. (A) Froth floatation process used for the concentration of sulphide ore is based on the difference in wettability of different minerals. The metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water. N a as collector. Other examples of collector include ethyl xanthate and potassium ethyl xanthate.

Froth Flotation Method: This method is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in water. To this are added, Collectors and Froth Stabilizers. Collectors (pine oils, fatty acids etc) increase the non-wettability of the metal part of the ore and allows it to form a froth.

The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide minerals water-repellant (hydrophobic) while leaving the other minerals wetted (hydrophilic).

The flotation process in seawater is highly complex and multifaceted, wherein the chemistry is very different to that of pure water. The high saline environment compresses the electrical double layers resulting in (i) enhancement of the floatability for surfaces that are already hydrophobic; (ii) mitigation of the slime coatings; (iii) increase of the entrainment; (iv) reduction of the bubbles ...
