The process was not froth flotation but used oil to agglomerate (make balls of) pulverised sulphides and buoy them to the surface, and was patented in 1898 with a description of the.

Froth Flotation - Department of Chemical EngineeringFroth flotation can be adapted to a broad range of mineral separations, as it is possible to use chemical treatments to selectively alter mineral surfaces so that they have the necessary properties for . definition of the ratio of concentration: . Table 1: Grade/recovery performance of a hypothetical copper ore flotation process.copper flotation description,Copper Flotation - ChemistryElmhurst - Elmhurst CollegeRemember 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 line) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills).

pH / ORP measurement Copper floatation process

Application Description AD/ANAINST/001–EN. pH / ORP measurement. Copper floatation process. Mining. Separating minerals by floatation. The flotation process can separate a required mineral such as copper, nickel, molybdenum or zinc from ore. Flotation can separate this mineral from waste materials or from another.

Copper Mining and Processing: Processing of Copper Ores .

This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis. Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is further processed.
