Introduction

Reverse flotation of coal can be explained as a process where valuable minerals are depressed, while undesired and unhealthy minerals are floated with the help of some reagents. ... On the other hand, like undesired minerals, valuable ones like vanadium, germanium, etc.

Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent. Leaching can occur naturally seen from plant substances (inorganic and organic), solute leaching in soil, and in the decomposition of organic materials.

An object floats when the weight force on the object is balanced by the upward push of the water on the object. If the weight force down is larger than the upward push of the water on the object then the object will sink. If the reverse is true then the object will rise rising is the opposite of sinking.

Solution Pine oil is added in the froth flotation method to create froth or bubble so that metal can be purify easily because pine oil prevents the ore from gangue for further mixing. Pine oil also acts as best substance for forming froth for the minerals. It also increases the non-wettability of mineral particles. Only supplied ores are concentrated by froth flotation process because pine oil selectively wets the supplied ore and hence brings it to the froth The supplied ores preferably wetted by the oil and the gangue with the water. Pine and olive oil are used as frothing agents in the process. The copper minerals and waste rock are separated at the mill using froth flotation. Air is blown into the tanks and agitated like a giant blender, producing a foamy froth. The chalcopyrite grains become coated with xanthine molecules with their hydrophobic ends waving around trying desperately to get out of the water. The basic factors, principles and variables affecting froth flotation are enumerated in condensed form be the Ore. Those variable results to be watched for and recorded are: Recovery, Grade of concentrate, Rate of flotation.

Hydraulic washing is a type of gravity separation, which is based on gravity differences between the ore and the gangue particles. In this process, the lighter gangue particles are washed away by a stream of water, leaving behind the heavier oreFroth flotation method is used for the concentration of sulphide ores. The method is based on the preferential wetting properties with the frothing agent and water. In the given options, Galena (PbS) being a sulphide ore is concentrated by froth floatation process. Galena is best concentrated by froth floatation method. Froth floatation method is used to concentrate sulphide ores. Magnetite (Fe3O4) is an ore of iron. Malachite (CuCO(OH)) is an ore of copper and cassiterite (SnO).sulphide ores are concentrated by "Froth floatation" and apart from pyrolusite (MnO2), all are sulphide ores. So, pyrolusite is not concentrated by froth floatation process.
