Froth Flotation (Sulphide & Oxide) ... Pyrite is depressed in flotation process to improve the concentrate grades of pb, zn and cu or bulk , in order to reduce onward smelting process cost. ... First a concentrated bulk of Lead and Copper and Zinc floats pyrite depresses a Ph of 7.5 to 8.0; Copper Lead separation. Then fleet zinc and pyrite ...
This process is called concentration of ore. The principle of froth flotation process is that sulphide ores are preferentially wetted by the pine oil, whereas the gangue particles are wetted by the water. In this process, a suspension of a powdered ore is made with water. In this process, a suspension of a powdered ore is made with water.

Extraction of copper from copper pyrites (CuFeS2) Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. Live Chat.
Can you list the factors affects the floatability of pyrite from refractory low grade ore. I used a Wemco lab flotation cell and aimed on analysing factors like collector dosages (PAX), Activator (Copper sulphate),MIBC , pH and others like pulp density and particle size (70 and 150 microns) .However how these factors affect the floatability of the pyrites from low grade refractory ore.
Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains.
CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION TO CONCENTRATION OF LOW GRADE IRON ORES A. Vidyadhar and R. Singh INTRODUCTION Froth flotation is a process used to separate minerals, suspended in liquids, by
Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. 1. The volatiles like sulphur and arsenic escape as gases S + O 2-----> SO 2 4AS + 3O 2----
Froth Flotation Process Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores.
