Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.
For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral's color. This is because the froth is becoming purer as the unwanted …
To start with I will give you a simplified description of how selective froth flotation works, lets start over again with a description of the equipment and why it works.. When the grinding circuit is finished with the ore it will be ground very fine and the density of the slurry will be between 30% to 45% solids.
Flotation machines constitute the basic equipment for useful minerals recovery from non-ferrous ores and other raw materials by flotation. They can operate also as individual flotation cells. Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies. The Flotation Cell is aerated to produce bubbles and agitated to …
Froth floatation process is used for the sulphide ores. In this method, wetting of the ore by an oil takes place. A strong current of air is blown through the suspension, producing a heavy froth or on the surface. The metal sulphide is wetted by the oil but the gangues is not and the sulphide-oil mixture is carried to the surface by films ...

In the first cell of each machine, sometimes in the first two cells, a finished concentrate is made. The froth from the remaining cells, which contains a good deal of gangue slime, is sent to a ten-cell M.S. Machine (24-in. impellers) and cleaned with no further reagents except a small quantity of sodium silicate to depress the gangue.
Offering higher selectivity than traditional sulfide ore flotation chemicals, our broad portfolio of flotation reagents includes collectors tailored for base metals, precious metals and …

Q. One of the processes used for concentration of ores is Froth floatation process. This process is generally used for concentration of sulphide ores. Sometimes in this process we add NaCN as a depressant. NaCN is generally added in case of ZnS and PbS minerals. What is the purpose of addition of NaCN during the process of Froth floatation ?
Process Optimisation. Analytics. ... Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
Spodumene theoretically contains 8.03% Li2O and therefore the production of this mineral is greatly increasing because of the expanded use of lithium in the manufacture of high temperature insoluble lubricants, ceramics, pyrotechnics, non-ferrous welding fluxes, air purifying agents, and hydrogen isotopes.

The process of froth floatation starts with the step known as comminution process in which the surface area of the ore is increased. In this step, the ores are crushed into very fine powder sized particles and mixed with water. The mixture obtained is called Slurry. This pulp is added in the container filled with water and then air jets are ...
N a C N is sometimes added in the froth floatation process as a depressant when Z n S and P b S minerals are expected because: N a C N is never added in froth floatation process; Z n S forms soluble complex N a 2 [Z n (C N) 4] while P b S form froth; P b (C N) 2 is precipitated while no effect on Z n S form froth; P b S forms soluble complex N ...
