Concentration of Ores: Hydraulic Washing, Froth Flotation
Sol: Gold and silver ores are concentrated by leaching. In this method, we treat the ore with a suitable reagent in which ore is soluble but impurities do not. Thus, impurities are removed by filtration. Among galena, copper pyrites, cinnabar and Argentine, Argentite being silver ore is concentrated by chemical leaching method.

Acid Leaching - Copper Ore Treatment Method
PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.

Hydrocyclone Working Principle
The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE. Unlike the rake and spiral classifiers, the overflow

Process of concentrating copper ore
Process of concentrating copper ore. The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

Ore of copper is not concentrated by hydraulic washing
Aside from cuprite (Cu2O) and tenorite (CuO), most of the other minerals of copper are sulfides and Cu(I) salts. These salts, just like pyrite (FeS) are susceptible to oxidation by oxygen. In addition, the sulfides of minerals are prone to react with water in acid-base reactions to form cuprite or tenorite.
