Copper Flotation - 911 Metallurgist

16/05/2016  Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter. Lime is nearly always used for maintaining the alkalinity of the circuit and depressing any pyrite present. The reagent

after two minutes of flotation. A faster floating copper porphyry flotation test, however, may finish in five minutes and a first concentrate may need to be collected after 20 seconds. Depending on one’s circumstances, some deviation may be required from the recommended test conditions (eg use of high

SOME ASPECTS OF LABORATORY FLOTATION OF Co-Cu

laboratory flotation on an individual basis in order to arrive at an acceptable flotation technique Laboratory flotation testwork was carried out on three different samples from the DRC in attempts to isolate some of the more important variables affecting the flotation of copper and cobalt oxide minerals from these weathered deposits. This paper describes some

1 Froth Flotation – Fundamental Principles

This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from 100%: % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper

27/06/2015  Using as a basis the three sizes of “Sub-A” Laboratory Flotation Machines available, namely the Nos. 5, 7 and 8, these plants can be furnished to fit each particular requirement. The No. 5 has a capacity of 50 to 150 pounds an hour, the No. 7 of 200 to 500 pounds an hour, while the No. 8 will handle 1,500 to 2,500 pounds an hour.

Flotation Reagents - 911 Metallurgist

08/06/2016  Flotation Activators What are Flotation Activators used for? The function of activators is to render floatable those minerals which normally do not respond to the action of promoters. Activators also serve to render floatable again minerals which have been temporarily depressed in selective flotation. Sphalerite depressed with cyanide and zinc sulphate can be activated with copper sulphate and it will

Effects of particle size on flotation performance in the ...

15/02/2019  In this investigation, the effects of particle size on flotation parameters of copper-gold and lead were studied by flotation kinetic analysis using the determinate reagent dosages. Flotation conditional tests were carried out to find out the optimum dosage for flotation kinetic study with various size fractions. Six flotation kinetic models were adopted for fitting the test data of copper, lead and

The Importance of pH in Flotation - 911 Metallurgist

10/08/2015  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 able to
