Test results are presented for two dry processing methods of high tension/electrostatic separation and pneumatic tabling as well as two wet methods of gravity tabling and froth flotation Each wet mineral separation method yielded two clean products following a limited number of cleaning and scavenging operations one product graded 95 to 98 Flotation in mineral processing method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is the surfaces are either repelled or attracted by water The flotation process was developed on a commercial scale early in the 20th century to mineral processing Flotation separation

The sulphidized lead minerals are subjected to flotation using xanthates or mercaptans and pine oil to produce a flotation concentrate which is cleaned two times to produce a high grade marketable lead concentrate The flotation tailing from the lead section passes to a wet cyclone to make a primary sand slime separationFloatation Separation Floatation is a main method to separate the ores by the different natures of wetting by water The hydrophobic mineral will be gathered on the bubbles and floats on the surface However the hydrophilic minerals will stay in the water Applies for the following ores

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation classification magnetic separation and leaching Gravity separation dates back to at least BC when Egyptians used the technique for separation The common mineral separation processes such as classification heavy media separation and froth flotation can be utilized in the separation of plastics this has been intensively reviewed in a recent publication by Buchan and Yarar

Froth flotation is a method of mineral separation in fluid which relies on the difference between the chemical composition of minerals compared to gangue Mineral Flotation International Mining Flotation has been at the heart of the mineral processing industry for over 100 years addressing the ‘sulphide’ problem of the early s and In such a case the conventional separation methods based on the bulk properties would not be appropriate To separate a mineral mixture the difference in the surface properties of the minerals must be utilized and the separation methods based on the interfacial properties such as flotation
