what ph is commonly used in copper ore flotation

Improve Copper Production by Controlling PH in Flotation

Rich copper concentrate is produced from crude copper sulfide ore by means of a flotation procedure that takes benefit from the physical and chemical properties of small copper ore allergens To optimize the production rate of copper, pH control is essential inside the flotation tanks.

Processing copper-porphyritic ore

Pyrite occurs commonly with copper sulfides, while pyrrhotite occurs less often Nonmetallic minerals encountered most often are quartz, silicates, sericite and barite All copper sulfides are processed through flotation using xanthates at 6-12 pH When pH values are lower, it is better to use aeroflot-type reagents instead of xanthogenat.

A Copper Oxide Ore Treatment by Flotation

Abstract: Depressants used in flotation can inhibit floatable gangue minerals to improve concentrate grade In this paper, four different commonly used depressants were adopted in order to investigate the effect of depressants on chalcopyrite index and to investigate their inhibition effects on chalcopyrite flotationThe experimental results indicate that, in the flotation system of natural pH.

The Importance of pH in Flotation

In flotation, pH control is a vital method to control selective mineral separation A standard depressant that is used is an Alkali An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE This is very important The ore may be either alkaline or Acidic To have a positive control over flotation, it is necessary to be.

Copper-Molybdenum ores

Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability Further, because optimum moly flotation pH is at 7-8 while optimum copper selectivity is typically in the 9.
