Froth flotation . Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic. This is used in mineral processing, paper recyclingand waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Bench scale flotation is used to determine how the reagents affect flotation performance when the scale of flotation and slurry density is increased. As such this paper is synopsis of a more in depth thesis research effort [9]. Methods and Materials The ore samples used in this flotation research were obtained from Mountain Pass Mine in California.

Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.

The theoretical grade-recovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process. The theoretical grade-recovery can be readily used to quickly identify potential recovery

Froth flotation will remain a key unit process for the treatment of iron ores for the decades to come with the overarching challenge best described as being the need to modify and improve existing procedures and processing conditions so as to maintain an acceptable iron grade-recovery response in the face of ores and feedstock that will be finer, more complex, lower in grade, more goethitic in

Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills) to make bubbles
